4. GERNERAL DESCRIPTION
The implemented Advanced Fusion Gauge algorithm calculates the remaining capacity by analyzing voltage,
current, temperature and other relevant data.
4.1 MEASUREMENT
4.1.1 Gas Gauging
The SH366002 implements Advanced Fusion Gauge algorithm combined with Coulomb Counting and Open
Circuit Cell Voltage Measurement, to achieve the smart battery gas gauging, according to currently measured cell
voltage, temperature, current, temperature and remaining capacity.
4
V0162
SH366002 SBS Solution User Guide
During charge or discharge period, the SH366002 updates the remaining capacity based on Coulomb Counting
every second. No matter in any mode(CHG, DSG or Relaxation mode), the SH366002 adjusts the capacity
according to the measured voltage, current, temperature and other relevant data as long as it meet some certain
conditions. SH366002 automatically compensates for aging, temperature, and discharge rate, providing accurate
State of Charge (SOC) over a wide range of operating conditions.
NominalAvailableCapacity( )(NAC) represents the uncompensated remaining capacity of the battery.
FullAvailableCapacity( )(FAC) represents the uncompensated full charge capacity of the battery.
RemainCapacity( )(RC) represents the compensated remaining capacity of the battery
FullChargeCapacity( )(FCC) represents the compensated full charge capacity of the battery
4.1.2 Gauge Related Registers
4.1.2.1 Dsg Current Threshold
This register is used as a threshold to determine if actual discharge current is flowing out of the cell. This threshold
should be set low enough to be below any normal application load current but high enough to prevent noise or drift
from affecting the measurement.
4.1.2.2 Chg Current Threshold
This register is used as a threshold to determine if actual charge current is flowing into the cell. This threshold
should be set low enough to be below any normal charge current but high enough to prevent noise or drift from
affecting the measurement.
4.1.2.3 Quit Current, Dsg Relax Time, Chg Relax Time, Quit Relax Time
When the current flowing in or out the battery remains above Quit Current for a period greater than Quit Relax
Time, the system quits relaxation mode. The default value of Quit Current should be greater than Standby
Current.
Either of the following criteria is met to enter Relaxation mode:
1. | AverageCurrent( ) | < | Quit Current | for Dsg Relax Time.
2. | AverageCurrent( ) | < | Quit Current | for Chg Relax Time.
After about 6 minutes in relaxation mode, SH366002 attempts to take accurate OCV readings with setting
[OCVTAKEN] in Flags() to 1. An additional requirement of dV/dt < 4 μV/sec is required for the SH66002 to
perform Qmax updates. These updates are used in the Fusion Gauge algorithms. It is critical that the battery
voltage be relaxed during OCV readings and that the current is not higher than C/20 when attempting to go into
relaxation mode.
5
V0162
SH366002 SBS Solution User Guide
4.1.2.4 Discharge Termination Voltage
The value of discharge terminate voltage is set by Terminate Voltage and the corresponding Remaining Capacity
is 0.
4.2 CHARGE CONTROL
4.2.1 Charge Termination
Charge termination voltage can be specified by users. It is Charging Voltage (default) when [JEITA] flag in
PackconfigC is set to 0, and is a corresponding JEITAChgVOL when [JEITA] flag in PackconfigC is set to 1.
SH366002 detects charge termination when all the below conditions are satisfied:
1. Pack Voltage >Selected Charging Voltage - Taper Voltage;
Charging Voltage,[JETIA] 0
JEITAChgVOL, [JEITA] 1
Selected Charging Voltage=
2. During two consecutive periods of Current Taper Window, the AverageCurrent< Taper Current;
3. During the same periods, the accumulated change in capacity ≥ Min Taper Capacity.
When this occurs, the [CHG] bit of Flags( ) is cleared.
If the [RMFCC] bit of PackConfiguration is set, NAC is set equal to FAC as well as RC is set equal to FCC.
If the TCA Set% is set as ‘-1’, the parameter is invalid; if as the other value, when the SOC is greater than the
threshold set in the TCA Set%, the [CHG] bit will be cleared.
If the TCA Clear% is set as ‘-1’, the parameter is invalid; if as the other value, when the SOC is lower than the
threshold set in the TCA Clear% , the [CHG] bit will be set.
If the FC Set% is set as ‘-1’, the parameter is invalid, the [FC] bit will be set only when Charge Termination occurs;
if as the other value, when the SOC is greater than the threshold set in the FC Set%, the [FC] bit will be set.
If the FC Clear% is set as ‘-1’, the parameter is invalid; if as the other value, when the SOC is lower than the
threshold set in the FC Clear% , the [FC] bit will be cleared.
4.2.2 JEITA Charging Profile
The fusion gauge provides full support for the JEITA charging algorithm, which employs separate constant-current
constant-voltage (CCCV) charging parameters depending on the measured Temperature(). The allowable
charging range is divided into four regions defined by T1 Temp, T2 Temp, T3 Temp, T4 Temp, and T5 Temp,
each with its own dedicated ChargingCurrent() and ChargingVoltage() values.
6
V0162
SH366002 SBS Solution User Guide
• If Temperature() < T1 Temp, ChargingCurrent() and ChargingVoltage() are set to 0.
• If T1 Temp ≤ Temperature() ≤ T2 Temp, T1-T2 Chg Current and T1-T2 Chg Voltage are reported.
• If T2 Temp T4 Temp without active charging, a charge inhibit condition is indicated by setting
the Flags()[CHG_INH] bit to 1 and clearing ChargingCurrent() and ChargingVoltage() to 0.
4.3 TEMPERATURE MEASUREMENT
The SH366002 measures battery temperature via two ways:
1. When the bit [TEMPS] of the PackConfig( ) is set, external Temperature measurement is enabled;
2. When the bit [TEMPS] of the PackConfig( ) is cleared, external Temperature measurement is disabled and the
temperature will be measured via the on-chip temperature sensor;
8
V0162
SH366002 SBS Solution User Guide
If the [TEMPS] =1, an external 10KΩ thermistor with negative temperature coefficients(for example: 103AT) is
necessary to be connected between the VCC and TEMP pins. Additional circuit information is shown in the
Reference Schematic.
4.3.1 Charge Over Temperature
If during charging, Temperature( ) reaches the threshold of OT Chg for a period of OT Chg Time and
AverageCurrent( ) > Chg Current Threshold , then the [OTC] bit of Flags( ) is set. When Temperature( ) falls to
OT Chg Recovery, the [OTC] of Flags( ) is cleared.
If OT Chg Time=0, the feature is disabled.
4.3.2 Discharge Over Temperature
If during discharging, Temperature( ) reaches the threshold of OT Dsg for a period of OT Dsg Time, and
AverageCurrent( ) ≤ - Dsg Current Threshold, then the [OTD] bit of Flags( ) is set. When Temperature( ) falls
to OT Dsg Recovery, the [OTD] bit of Flags( ) is cleared.
If OT Dsg Time = 0, the feature is disabled.
4.4 PROTECTION FLAGS
4.4.1 Tab Disconnect Detection
A tab disconnect condition is detected and the Flags()[TDD] flag is set when Qmaxcal < TDD Percent * Design
Capacity under the Fusion Gauge Qmax update conditions. And [TDD] flag is cleared when Qmaxcal > TDD
Percent * Design Capacity under the same conditions. The above Qmaxcal is the calculated Qmax duing the
current DSG-Relax-CHG-Relax cycle.
An interrupt can be configured to trigger on the (STE or SWI) pin when the tab disconnect condition is detected.
Enable/disable of the tab disconnect detection feature is controlled via the [TDDEN] bit in PackConfiguration B.
The [TDD] of Flags() can be configured to control interrupt pin (STE or SWI) by enabling interrupt mode. See
Section 6.2, Interrupt Mode, for details.
4.4.2 Internal Short Detection
The fusion gauge can indicate detection of an internal battery short by setting the [ISDEN] bit in
PackConfiguration B. If Cell Temperature ≥ 0 degC, the gauge compares the self-discharge current calculated
based on the RELAX mode(MinISDTime later in RELAX mode) to the AverageCurrent measured in the system.
The self-discharge rate is measured at 1 hour intervals. When battery SelfDischargeCurrent() is less than Design
Capacity / ISD Current threshold, the [ISD] of Flags() is set high.
The [ISD] of Flags() can be configured to control interrupt pin (STE or SWI) by enabling interrupt mode. See
Section 6.2, Interrupt Mode, for details.

4.4.3 STE_fuse Blow Function
Fuse can be blown by STE_fuse Blow Function. This function is enabled and disabled by subcommands
0x0091and 0x0092 respectively in Control command (0x00).
When the function is enabled, the fusion gauge detects the cell voltage and triggers STE pin state (set the STE pin
low or high according to Table 4.2 ) when cell voltage >STE_fuse Volt Set for STE_fuse Set Time. The STE pin
keeps high for STE_fuse Blow Time to blow fuse (fuse blown process) when the ‘1’ state in Table 4.2 is triggered.
During this process, Fuseflag(can be read by sub-command 0x0090) in Dataflash is updated to the following value
to indicate the fuse state.
Table 4.1 Fuseflag indicated state
Fuseflag
Condition
Indicated state
0x55
When no obvious current (|current|STE_fuse Volt) is detected. And also STE pin is set to high to blow fuse when the fusion gauge
detected STE_fuse Blow Time=0 and Fuseflag=0x55.
4.4.4 BATLOW/BATHIGH flags
SH366002 detects the cell voltage for low or high voltage alarm. [BATLOW] flag in Flags() will be set when lower
than BATLOW Set Threshold voltage is detected for BATLOW Set Time and cleared when cell voltage > BATLOW
Clear Threshold, and [BATHI] flag in Flags() will be set when more than BATHI Set Threshold voltage is detected
for BATHI Set Time and cleared when cell voltage < BATHI Clear Threshold.
4.5 TWI /SWI Communication Mode
SH366002 supports TWI Communication mode only (default) or TWI Communication / SWI Communication
compatible mode for system communication. SH366002 can respond TWI or SWI signals in same mode (the
Communication compatible mode) but not communicate in the two ways at the same time. The compatible mode is
non-effective until SH366002 receive some certain commands.
11
V0162
SH366002 SBS Solution User Guide
It is important to note that only under the condition of Pack Configuration [INTSEL] bit =0 can the communication
compatible mode be switch on resulting from that the SWI pin is also used as the respond pin by the Interrupt,
SE_Fuse and BTP Function etc.
4.6 ACCESS MODES
The SH366002 provides three security modes: FULL ACCESS, UNSEALED, and SEALED.

The difference between FULL ACCESS mode and UNSEALED mode is only FULL ACCESS mode allows
SH366002 to read/write access-mode transition key. In order to avoid conflict, the key must be different from the
CNTL DATA shown in Table 7.2.
4.6.1 FULL ACCESS / UNSEALED to SEALED
When SEALED-KEY is received via the Control( ) command, the SH366002 enters SEALED mode, setting the
[SS] bit and [FAS] bit. When in SEALED mode, the UNSEAL keys can be correctly received, but the system will
reenter the SEALED mode once a reset occurs.
4.6.2 SEALED to UNSEALED and UNSEALED to FULL ACCESS
Both Unseal Key and Full-Access Key are stored in data flash in two words. The first word is Key 0 and the
second word is Key 1. The order of the keys sent to SH366002 is Key 1 followed by Key 0. For example, if the
Unseal Key is 0x56781234, key 1 is 0x1234 and key 0 is 0x5678. Then Control( ) should supply 0x1234 and then
0x5678, to unseal the part.
5. Lifetime Data Logging Parameters
The Lifetime Data logging function helps development and diagnosis with the fusion gauge. The 0x0021
subcommand needs to be enabled for lifetime data logging functions to be active. The fusion gauge logs the
lifetime data as specified in the Lifetime Data and Lifetime Temp Samples data flash subclasses. The data log
recordings are controlled by the Lifetime Resolution data flash subclass. The Lifetime Data Logging can be started
by setting the 0x0021 subcommand and setting the Update Time register to a non-zero value.
Once the Lifetime Data Logging function is enabled, the measured values are compared to what is already stored
in the data flash. If the measured value is higher than the maximum or lower than the minimum value stored in the
data flash by more than the Resolution set for at least one parameter, the entire Data Flash Lifetime Registers are
updated after at least LTUpdateTime.
12
V0162
SH366002 SBS Solution User Guide
LTUpdateTime sets the minimum update time between DF writes. When a new maximum or minimum is detected,
a LT Update window of [update time] seconds is enabled and the DF writes occur at the end of this window.
Internal to the fusion gauge, there exists a RAM maximum/minimum table in addition to the DF
maximum/minimum table. The RAM table is updated independent of the resolution parameters. The DF table is
updated only if at least one of the RAM parameters exceeds the DF value by more than resolution associated with
it. When DF is updated, the entire RAM table is written to DF. Consequently, it is possible to see a new
maximum/minimum value for a certain parameter even if the value of this parameter never exceeds the maximum
or minimum value stored in the data flash for this parameter value by the resolution amount.
Figure 5.1 Lifetime logging data record example
Take Figure 5.1 for example, when the Life Time Data Logging is enabled, ΔTemp, ΔVoltage, ΔCurrent are
detected every second. The above ΔTemp, ΔVoltage, ΔCurrent definition and their trigger conditions are listed
below.

Once any of the above trigger conditions is satisfied, the fusion gauge records all of the max/min Temperature(),
Voltage() and Current() during the following Lifetime Update Time and updates the max/min values which are
higher or lower than the former value to Dataflash at the end of the Lifetime Update Time.
As shown in Figure 5.1, Lifetime Logging Data triggered if ΔVoltage > LifeTime Delta Volt, and Lifetime Max
Temp, Lifetime Max Volt, Lifetime Min Volt and Lifetime Max CHG CUR were updated at the end of the Lifetime
Updete Time.
The Life Time Data Logging of one or more parameters can be reset or restarted by writing new default (or
starting) values to the corresponding data flash registers through SEALED or UNSEALED access as described
below. However, when using UNSEALED access, new values take effect only if the device is reset within LT
Update Time after the DF is loaded with new values.
The logged data in Lifetime Data subclass (subclass ID = 59) can be read and written in both SEALED and
UNSEALED modes. However, in SEALED mode, access to this subclass is using a process identical to accessing
Manufacturer Info Block B. The DataFlashBlock() command code is 4. More detail please refer to the 0x61
command.
The subclasses Lifetime Resolution (subclass ID = 66) and Lifetime Temp Samples (subclass ID = 59) that
contain settings for lifetime data logging can be configured only in UNSEALED mode using the regular DF access
method.
The Lifetime resolution registers contain the parameters which set the limits related to how much a data parameter
must exceed the previously logged maximum/minimum value to be updated in the lifetime log. For example, V
must exceed MaxV by more than Voltage Resolution to update MaxV in the data flash.
6. System Control Function
The fusion gauge provides system control functions which allows the fusion gauge to enter shutdown mode in
order to power-off with the assistance of external circuit or provides interrupt function to the system.
Table 6.1 shows the configurations for STE and SWI pins.

CONTROL_STATUS() function. The STE pin shutdown function is disabled.
(3) SWI pin is used for communication and SWI Host Interrupt Feature is available.
6.1 shutdown mode
By using STE pin, the fusion gauge can be made to power-off through an external circuit. This feature is useful to
shutdown the fusion gauge in a deeply discharged battery to protect the battery.
The following bits are used to configure and control STE pin:
1. Two Control Status bits signals the operation of the STE pin:
[STE]
- bit15
-- Status bit indicating the STE pin is active. Default is 0.
[SHUTDOWN]
- bit7
-- indicates the shutdown feature is enabled. Default is 1 (enabled)
2. Two control() sub-commands enable or disable shutdown functionality:
SET_SHUTDOWN (0x0013)
-- enables STE pin functionality (sets SHUTDOWN status bit)
CLEAR_SHUTDOWN (0x0014) -- disables STE pin functionality (clears SHUTDOWN status bit)
3. Two Data Flash bits in pack configuration register control the operation of the STE pin:
[STE_PU]
- bit3
-- Pull-up enable for STE pin when its state is 1.
[STE_POL]
- bit2
-- Polarity for STE pin when shutdown is enabled.
By default the STE pin is in normal state for all modes of operation. By sending SET_SHUTDOWN sub-command
or setting [STE_EN] bit in PackConfiguration Register, the [SHUTDOWN] bit is set and the shutdown feature is
enabled.
In the shutdown mode, the STE pin is used to signal external circuit to power-off the fusion gauge. This feature is
useful to shutdown the fusion gauge in a deeply discharged battery to protect the battery. By default, the
15
V0162
SH366002 SBS Solution User Guide
Shutdown Mode is in normal state. By sending the SET_SHUTDOWN subcommand or setting the [STE_EN] bit in
PackConfiguration register, the [SHUTDWN] bit is set and enables the shutdown feature. When this feature is
enabled and [INTSEL] is set, the STE pin can be in normal state or shutdown state. The shutdown state can be
entered in HIBERNATE mode (only if HIBERNATE mode is enabled due to low cell voltage), all other power
modes will default STE pin to normal state. Table 6.2 shows the STE pin state in normal or shutdown mode. The
CLEAR_SHUTDOWN subcommand or clearing [STE_EN] bit in the PackConfiguration register can be used to
disable shutdown mode.
The STE pin will be high impedance at power-on reset (POR), the [STE_POL] does not affect the state of STE pin
at POR. Also, [STE_PU] configuration changes will only take effect after POR. In addition, the [INTSEL] only
controls the behavior of the STE pin; it does not affect the function of [SE] and [SHUTDWN] bits.

6.2 Interrupt Mode
By utilizing the interrupt mode, the system can be interrupted based on detected fault conditions as specified in
Table 6.5 when the corresponding bit is set in Interrupt Config(see Table 7.11). The STE or SWI pin can be
selected as the interrupt pin by configuring the [INTSEL] bit. In addition, the pin polarity can be configured
according to the system needs as described in Table 6.3 or Table 6.4. More details please refer to Table 6.1.

registers.
6.3 Battery Trip Point interrupt Function
To provide increased flexibility for capacity-based interrupts to the host, the fusion gauge incorporates a Battery
Trip Point (BTP) function that allows the system to dynamically update the traditional SOC1 Set Threshold and
SOC1 Clear Threshold at runtime using the BTPSOC1Set() and BTPSOC1Clear() standard commands. These
thresholds are used to trigger an interrupt on the SWI pin whenever the set or clear thresholds are crossed
following update to the BTPSOC1Set() and BTPSOC1Clear() values.
Configuration of the interrupt polarity and enable/disable of the feature is provided via the PackConfiguration
[INTPOL] and PackConfiguration C [BTP_EN] bits, respectively, while initialization values for the interrupt set
and clear thresholds are programmed in SOC1 Set Threshold and SOC1 Clear Threshold as normal.
17
V0162
SH366002 SBS Solution User Guide
When BTP is enabled, the fusion gauge continuously compares RemainingCapacity() with the values
programmed in BTPSOC1Set() and BTPSOC1Clear() to determine whether or not it has crossed below the set or
above the clear threshold. Once a threshold is crossed, additional conditions are verified to guard against an
unintended interrupt trigger. For the BTP set threshold, the direction of current flow is checked to confirm that a
discharge event is occurring. If true, the Flags()[SOC1] bit is set to 1 and an interrupt asserts on the SWI pin. For
the BTP clear threshold, the device again checks the direction of current flow to ensure that a charge event is
occurring. Afterwards, an internal variable is examined to determine whether or not a change in the state of
Flags()[SOC1] has already occurred due to a prior clear threshold crossing. If true, no change is made and a new
interrupt will not fire, however, it is implied that a pre-existing interrupt will still be asserted. If false, the current state
of Flags()[SOC1] is flipped to its opposite value and an interrupt subsequently triggered on the SWI pin. In this
way, the correct behavior is guaranteed in cases where the host updates the BTP set and clear thresholds
diligently based on SWI interrupts but also when there is a failure to update the thresholds. If, at any time, new
values are written to either BTPSOC1Set() or BTPSOC1Clear() then the [SOC1] flag automatically reinitializes to
0 and the SWI pin de-asserts to its default state. The entire functional flow of the BTP feature is illustrated in
Figure 6.1, BTP Algorithm Flow.

SH366002 SBS Solution User Guide
Figure 6.1 BTP Algorithm Flow
In normal usage, the BTP thresholds are continuously updated by the host system at predetermined increments,
each time reinitializing the Flags()[SOC1] bit to 0 and waiting for the crossing of the next threshold to trigger a new
interrupt. If the thresholds are always updated after each interrupt, then it is implied that the crossing of a set or
clear threshold always triggers a new interrupt. This is highlighted below in Figure 6.2, BTP Configuration with
Multiple Thresholds.
19
V0162
SH366002 SBS Solution User Guide
Figure 6.2 BTP Configuration with Multiple Thresholds([INTPOL]=0)
However, it is possible that the host may fail to write new thresholds or experience a significant delay in attempting
to do so. In this case, there could be an occurrence where the clear threshold is crossed after an interrupt due to a
prior set threshold crossing. Thus, the [SOC1] bit would experience a change but a new interrupt would not be
triggered on SWI. Thus, continued crossings without updates to BTPSOC1Set() or BTPSOC1Clear() will only
result in changes to Flags()[SOC1].
If BTPSOC1 Set() is lower than(default) or equal to BTPSOC1 Clear() the SWI pin state and [SOC1] flag respond
according to the Figure 6.1 and Figure 6.2. If BTPSOC1 Set() is higher than BTPSOC1 Clear(), the SWI pin state
and [SOC1] flag respond according to the Figure 6.1 and Figure 6.2 in non-charging mode, but according to the
condition of RC()>BTPSOC1Set() in charging mode.
Note: 1) The interrupt pin is STE pin when [INTSEL] in Pack configuration is set, and SWI pin when cleared.
2) The interrupt pin is default to be pulled up for BTP function.

7.1.1.25 ENTER_CAL: 0x0081
This command instructs the SH366002 to enter calibration mode. The gas gauge will exit calibration mode
automatically if no other calibrate sub-command was sent in 5 minutes. This command is only available in
UNSEALED mode.
7.1.2 AtRate( ): 0x02/0x03
The AtRate( ) read-/write-word function is the first half of a two-function command call-set used to set the AtRate
value used in calculations made by the AtRateTimeToEmpty( ) function. The AtRate( ) units are in mA.
The AtRate( ) value is a signed integer, with negative values interpreted as a discharge current value. The
AtRateTimeToEmpty( ) function returns the predicted operating time at the AtRate value of discharge. The
default value for AtRate( ) is zero and will force AtRateTimeToEmpty( ) to return 65,535.
7.1.3 AtRateTimeToEmpty( ): 0x04/0x05
This read-only function returns an unsigned integer value of the predicted remaining operating time if the battery is
discharged at the AtRate( ) value in minutes with a range of 0 to 65,534. A value of 65,535 indicates AtRate( ) ≥ 0.
The fusion gauge updates AtRateTimeToEmpty( ) within 1 s after the system sets the AtRate( ) value. The fusion
gauge automatically updates AtRateTimeToEmpty( ) based on the AtRate( ) value every 1s.
7.1.4 Temperature( ): 0x06/0x07
This read-only function returns an unsigned integer value of the battery temperature in units of 0.1K.
7.1.5 Voltage( ): 0x08/0x09
This read-only function returns an unsigned integer value of the measured cell-pack voltage in mV with a range of
0 to 6000 mV.
7.1.6 Flags( ): 0x0a/0x0b

7.3 DATA FLASH DESCRIPTION
7.3.1 Accessing the Data Flash
The SH366002 data flash is a non-volatile memory that contains SH366002 initialization, default, cell
status,calibration, configuration, and user information. These information can be accessed by the host. But only
Manufacture information can be accessed in SEALED mode.
These information data should be optimized and/or fixed during the development and manufacture processes.
They will be made into a file and can then be written to multiple battery packs.
Access data flash locations:
1. Send 0x00 to BlockDataControl( ) (0x61) as a set-up signal;
2. Send the data block No. to DataFlashClass( ) (0x3e);
34
V0162
SH366002 SBS Solution User Guide
3. Send the data block offset to DataFlashBlock( ) (0x3f) where 0 represents 0~31, 1 represents 32~63, and so
on.
4. The correct command address is then given by 0x40 + offset modulo 32. For example, to access Terminate
Voltage in the Gas Gauging class. Because the offset is 48, it must reside in the second 32-byte block.
Hence, DataFlashBlock( ) is issued 0x01 to set the block offset, and the offset used to index into the
BlockData( ) memory area is 0x40 + 48 modulo 32 = 0x40 + 16 = 0x40 + 0x10 = 0x50.
5. If a new value is written in flash, the new checksum must be sent to BlockDataCheckSum( ) (0x60) and the
next command should not be sent within 120ms.
6. If the block length is over 32 bytes, the whole class can be written or read by repeating step 4 and 5.
Note: Class 224~227 cannot be written separately. All the 4 classes must be written together. Recommend steps
are listed below:
1. Send Command 0x0094 to Control(0x00)
2. Wait 200 ms, then send command 0x0095 to Control(0x00), and read Control. If LSB 4 is set, wait 200ms and
re-excute step 2. If LSB 5 is set, that means these classed in this chip cannot be written. If LSB 4 is clear,
goto step 3
3. Send 0x00 to BlockDataControl( ) (0x61) as a set-up signal
4. Send 224 to DataFlashClass( ) (0x3e);
5. Send the data block offset to DataFlashBlock( ) (0x3f) where 0 represents 0~31, 1 represents 32~63, and so
on.
6. Send data buffer to 0x40~0x5F
7. If a new value is written in flash, the new checksum must be sent to BlockDataCheckSum( ) (0x60) and the
next command should not be sent within 250ms.
8. If the block length is over 32 bytes, the whole class can be written or read by repeating step 4 and 5.
9. Write class 225~227
10. Send Command 0x0095 to Control(0x00). Wait 250ms then reset SH366002
7.3.2 Manufacture Information Blocks
The SH366002 contains 96 bytes of user programmable data flash storage: Manufacturer Info Block A,
Manufacturer Info Block B, Manufacturer Info Block C. The method for accessing these memory locations is
slightly different, depending on whether the device is in UNSEALED or SEALED mode.
In UNSEALED mode, when 0x00 has been written to BlockDataControl( ), accessing the Manufacturer Info
Blocks is identical to accessing general data flash locations.
35
V0162
SH366002 SBS Solution User Guide
Example: for Block B, DataFlashClass( ) is issued 58(0x3A) to set the class, the offset is 32~63, it must reside in
the second 32-byte block. Hence, DataFlashBlock( ) is issued 0x01 to set the block offset, and the BlockData( )
return the value of Manufacturer Info Block B.
When in SEALED mode, BlockDataControl( ) and DataFlashClass( ) commands are not available. Issuing a
0x01, 0x02, or 0x03 with the DataFlashBlock( ) command causes the corresponding information block (A, B, or C,
respectively) to be transferred to the command space 0x40…0x5f for editing or reading by the system. Upon
successful writing of checksum information to BlockDataChecksum( ), the modified block is returned to data
flash.
Note: Manufacturer Info Block A is read-only when in SEALED mode.

Min. voltage for Flash Update. Dataflash could not be modified when cell
voltage 0) or immediately (Full Sleep Wait Time ≤0).
During FULLSLEEP mode, the SH366002 periodically takes data measurements and updates its data set.
However, a majority of its time is spent in an idle condition. In this mode, the high frequency oscillator is turned off.
The power consumption is further reduced in this mode compared to the SLEEP mode.
The gauge exits the FULLSLEEP mode when there is any communication activity. While in FULLSLEEP mode,
the fusion gauge can suspend serial communications as much as 4ms by holding the communication line(s) low.
This delay is necessary to correctly process host communication, since the fusion gauge processor is mostly
halted in SLEEP mode.
8.4 HIBERNATE MODE
HIBERNATE mode should be used when the host system needs to enter a low-power state, and minimal gauge
power consumption is required.
1.
HIBERNATE due to the load current.
2.
The [HIBERNATE] bit of the CONTROL_STATUS register must be set.
3.
The gauge has taken a valid OCV measurement.
4.
The magnitude of the average cell current has fallen below Hibernate Current.
5.
No communication.
6.
The gauge is already in SLEEP or FULLSLEEP mode
7.
HIBERNATE due to the cell voltage.
8.
Cell voltage drops below the Hibernate Voltage.
9.
A valid OCV measurement has been taken.
10. No communication.
11. The gauge is already in SLEEP or FULLSLEEP
If the [SHUTDOWN] bit of CONTROL _STATUS is also set, the STE pin will be released in the state shown by
Table 7.2; thereby, allowing an optional external circuit to remove power from the gauge LDO.
Upon exiting HIBERNATE mode, the [HIBERNATE] bit of CONTROL_STATUS is cleared. Since any
communication activity wakes up the gauge from HIBERNATE mode, the host is required to set the
[HIBERNATE] bit of the CONTROL_STATUS register to allow gauge to re-enter HIBERNATE mode.
To disable the HIBERNATE mode, the Control( ) sub-command SET_HIBERNATE should not be used and
Hibernate Voltage and Current must be set to 0 in data flash.
