ETR25008-005
One Cell Li-ion/Li-polymer Linear Charger IC with Battery Temperature Detection
■GENERAL DESCRIPTION
The XC6804 is a Constant-Voltage (CV) and Constant-Current (CC) type charging IC for linear charging of single-cell Li-ion
batteries and Li-polymer batteries. The basic charging cycle consists of trickle charge mode followed by main charge mode.
This IC supports temperature control based on JEITA, making it possible to safely charge Li-ion batteries and Li-polymer
batteries by controlling the CV charge voltage and CC charge current according to the temperature. By connecting a resistor to
the charge status output pin, it is possible to check the charge condition via the charge status output (CSO) pin voltage. The IC
is housed in the small SOP-8FD or USP-6EL package with high heat dissipation, and a charge circuit can be configured using a
minimum of external components.

● Charging start
When a thermistor is connected to the THIN pin after a voltage is applied to the power input pin (①), or when a voltage is applied to the
power input pin after a thermistor is connected to the THIN pin (②), the power on reset function activates and initializes the internal counter.
After 200ms elapses in the case of ①, or 150ms in the case of ②, charging starts.
● Trickle charging: Less than 2 hours
Trickle charging determines if main charging of the Li-ion battery is possible. The Li-ion battery is charged at a trickle charge current that
is one-tenth the charge current set with the external resistor RISET. If the BAT pin voltage VBAT is above 2.9V in the charging start state,
trickle charging takes place for 1ms and then main charging begins. If VBAT is less than 2.9V, trickle charging takes place, and main charging
begins 50ms after 2.9V is detected. If the BAT pin voltage is less than 2.9V after 2 hours, the IC changes to the error state and stops
charging the Li-ion battery. In addition, the error in the trickle charge current increases if VBAT drops below about 1V.
● Main charging: Less than 10 hours
When the condition for transition from trickle charging is satisfied, it is determined that rapid charging of the Li-ion battery is possible and
the IC changes to the main charging state. In main charging, the IC charges a Li-ion battery at a CC charge current that is set with the
external resistor RISET. When the BAT pin voltage rises to the CV charge voltage in less than 10 hours and the charge current drops to the
charging completed current, and after 50ms elapses,the IC changes to the charging completed state and charging stops. If the charge
current is higher than the charging completed current after 10 hours, the IC changes to the error state and stops charging.
● Charging completed
When the charge current reaches the charge completion current, which is one-tenth the charge current set with the external resistor RISET,
and after 50 ms elapses, the IC changes to charging completed and stops charging the Li-ion battery. At this time, the charge status output
pin changes from ON to OFF. On the XC6804xxE, when the BAT pin voltage (VBAT) falls from the charge completion state to the recharge
voltage (VRCHG) or less, charging automatically restarts. When a voltage is reapplied to the power input pin or a Li-ion battery is reconnected
to the BAT pin in the charging completed state, the IC starts and charging begins.
● Error state
If it is determined that charging is abnormal in any state, the IC treats this as an error state and stops charging. When the power is turned
off and then on, or the battery is reinserted, the IC starts up gain and starts charging. An error state occurs if 2 hours elapses during trickle
charging, if 10 hours elapses during main charging, or if charging overvoltage or charging overcurrent is detected.
● Charging status output pin, CSO
The charge status output pin turns ON by Nch open drain output during trickle charging and main charging, and turns OFF after charging
is completed. An LED can be connected to enable confirmation of charging by illumination of the LED. If an abnormal condition is detected,
the charge status output pin repeats ON-OFF at 1kHz on the XC6804A, and turns off on the XC6804B. An error state indicates a state in
which 2 hours have elapsed during trickle charging, 10 hours have elapsed during main charging,or charging over-voltage or charging
over-current is detected.
● Charge current
The charge current ICHG of this IC can be set in the range 200mA to 800mA by means of the external resistance RISET. The relation
between RISET and ICHG is approximated by the equation below.
RISET (kΩ) = 15950 x ICHG -1.122 (mA)
(*1)
The XC6804xxD does not have the recharge function.

■ OPERATIONAL EXPLANATION (Continued)
● IC temperature monitoring function
In order to prevent destruction due to IC heat generation as well as abnormal charging due to thermal runaway, a thermal shutdown
circuit is incorporated into the IC. If the chip temperature rises to 115°C or higher and after 50ms elapses, this function turns off the output
driver and stops charging. When 50ms elapse with the chip temperature 105°C or less, this function returns the IC to the main charging
state and starts charging. Even when charging is stopped by this function, the tTRK and tCHG counts are continued.
● Dropout voltage monitoring function
To prevent reverse current from the Li-ion battery to the battery charger, this function monitors the dropout voltage between the BAT pin
voltage (VBAT) and power input pin voltage (VIN). When the VIN falls to VBAT + 40mV, the function turns off the output driver and switches the
backgating connection from the power pin to the BAT pin. When VIN rises higher than VBAT + 0.1V, this function is released, the output driver
turns ON, the driver backgate connects to the power pin and resumes charging, and the charge status output pin turns ON. Even when
charging is stopped by this function, the tCHG count is continued. When charging is completed, the charging status output pin maintains the
OFF state even if the function activates due to disconnection of the input power or otherwise.
● UVLO function
A UVLO function is incorporated. If the power input pin voltage, VIN falls to 3.8V or lower during charging, this function turns off the output
driver and stops charging. In addition, the charge status output pin changes to OFF. When the VIN rises to 4V or higher, the IC starts up and
charging begins. This function also detects voltage application to the power input pin.
● Charge over-voltage monitoring function
To prevent charging of a battery in the over-voltage state, this function stops charging if the BAT pin voltage rises to 4.45V or higher and
50ms elapses.
At this time, the charge status output pin repeats ON-OFF at 1kHz on the XC6804A, and turns off on the XC6804B. When voltage is
reapplied to the power input pin or the Li-ion battery is reconnected to the BAT pin, the IC starts up and charging begins.
● Charge over-current monitoring function
To prevent charging of a battery by excessive current, this function stops charging if the charge current rises to 1200 mA or higher.
At this time, the charge status output pin repeats ON-OFF at 1 kHz on the XC6804A, and turns off on the XC6804B. When voltage is
reapplied to the power input pin or the Li-ion battery is reconnected to the BAT pin, the IC starts up and charging begins.
● Recharge function
With the completion of charging, when the NTC thermistor temperature is 0°C or higher and less than 45°C, and the BAT pin voltage
(VBAT) falls to 3.9 V or less, charging resumes. (charging is resumed 150ms after the charge start state is entered.)
On the XC6804x4, if the NTC thermistor temperature is 45°C or higher and less than 60°C, charging automatically resumes when the
voltage falls to 3.75 V or less. This function is equiped only in the XC6804xxE, not in the XC6804xxD.

■OPERATIONAL EXPLANATION (Continued)
●Li-ion battery temperature monitoring function
The IC monitors the Li-ion battery temperature during charging by means of an NTC thermistor (“thermistor” below) connected to the
THIN pin. The charge voltage VBAC and the charge current IBAT are controlled based on the Li-ion battery temperature as shown below to
enable safe charging. The charge state changes 50 ms after the Li ion battery temperature reaches each of the change points.

Cold Operation
When 0°C < NTC Temperature ≤ 10°C, the charge current is limited to ICHG × 0.5. (*1)
When NTC Temperature ≤ 0°C, charging stops. (*2)
Normal Operation
When 10°C < NTC Temperature < 45°C, charging takes place with the charge current ICHG and the charge voltage at 4.2 V. (*1)
Hot Operation
When 45°C ≤ NTC Temperature < 60°C, the charge voltage changes to 4.05 V and charging continues. (*1)
When 60°C ≤ Thermistor Temperature, charging stops. (*2)
● XC6804x3 (3 temperatures monitoring)
Comparing to the XC6804x4, the XC6804x3 does not monitor at 60°C and charging stops at 45°C ≤ Thermistor Temperature. (*2)
● XC6804x2 (2 temperatures monitoring)
In contrast to the XC6804x4, the XC6804x2 does not have 10°C and 60°C monitoring, and stops charging when Thermistor Temperature
≤ 0°C and when Thermistor Temperature ≥ 45°C. (*2)
In addition, when 0°C< Thermistor Temperature ≤ 10°C, the charge current does not change from ICHG.(*1)
(*1)
During trickle charging, the charge current is limited to ICHG × 0.1.
(*2)
Even when charging is stopped, tTRK count and tCHG count are continued and the charge status output pin maintains the ON state.
The thermistor temperature detection of this IC conforms to the characteristics of the NCP15XH103F03RC of Murata Manufacturing Co., Ltd.

This IC uses an external thermistor to detect and control temperature with high accuracy. Please sufficiently test the position of the
external thermistor to ensure that it enables accurate temperature detection.
7.
8.
Reversing the polarity of the battery may cause destruction and is extremely dangerous. Never reverse the polarity of the battery.
Short-circuiting to neighboring pins may cause malfunctioning and destruction. Exercise sufficient caution when mounting and using
the IC.
9.
If a large ripple voltage occurs at the VIN pin, the IC may malfunction. Please test thoroughly.
10. Taking the temperature characteristics and the dispersion into consideration, please set the charge current not to exceed the range of
200mA to 800mA.
11. If the ISET pin is shorted to the GND, there is a possibility that the IC is destroyed before the over-current monitor function is activated.
12. When VBAT is 1V or less, the error range of the trickle charge current becomes big. When VIN – VBAT voltage is high in particular, please
pay attention when using as there are possibilities that a large trickle current flows.
13. In case that the impedance between BAT pin and Li-ion battery is high at the CV charging under the low temperature, there are
possibilities that VBAT oscillates and charge error takes place, so please place the Li-ion battery as close to the IC as possible.
