The TPS65011 device is an integrated power and
battery management IC for applications powered by
one Li-Ion or Li-Polymer cell and which require
multiple power rails. The TPS65011 provides two
highly efficient, 1.25-MHz step-down converters
targeted at providing the core voltage and peripheral,
I/O rails in a processor-based system. Both stepdown converters enter a low-power mode at light load
for maximum efficiency across the widest possible
range of load currents.

The TPS65011 also integrates two 200-mA LDO
voltage regulators, which are enabled via the serial
interface. Each LDO operates with an input voltage
range between 1.8 V and 6.5 V, allowing them to be
supplied from one of the step-down converters or
directly from the battery.

7.3.6 System Reset and Control Signals
The RESPWRON signal is used as a global reset for the application. It is an open drain output. The
RESPWRON signal is generated according to the Power Good comparator linked to VMAIN and remains low for
tn(RESPWRON) seconds after VMAIN has stabilized. When RESPWRON is low, PWRFAIL, MPU_RESET and INT
are also held low.

www.ti.com
SLVS501B – FEBRUARY 2004 – REVISED SEPTEMBER 2015
If the output voltage of MAIN is less than 90% of its nominal value, as RESPWRON is generated, and if the
output voltage of MAIN is programmed to a higher value, which causes the output voltage to fall out of the 90%
window, then a RESPWRON signal is generated.
The PWRFAIL signal indicates when VCC < UVLO or when the TPS65011 junction temperature has exceeded a
reliable value or if BATT_COVER is taken low. This open drain output can be connected at a fast interrupt pin for
immediate attention by the application processor. All supplies are disabled t(uvlo), t(overtemp) or t(batt_cover) seconds
after PWRFAIL has gone low, giving time for the application processor to shut down cleanly.
BATT_COVER is used to detect whether the battery cover is in place or not. If the battery cover is removed, the
TPS65011 generates a warning to the processor that the battery is likely to be removed and that it may be
prudent to shut down the system. If not required, this feature may be disabled by connecting the BATT_COVER
pin to the VCC pin. BATT_COVER is de-bounced internally. Typical de-bounce time is 56 ms. BATT_COVER
has an internal 2-MΩ pulldown resistor.
The HOT_RESET input is used to generate an MPU_RESET signal for the application processor. The
HOT_RESET pin could be connected to a user-activated button in the application. It can also be used to exit lowpower mode. In this case, the TPS65011 waits until the VCORE voltage has stabilized before generating the
MPU_RESET pulse. The MPU_RESET pulse is active low for t(mpu_nreset) seconds. HOT_RESET has an internal
1-MΩ pullup resistor to VCC.
The PB_ONOFF input can be used to exit low-power MODE. It is typically driven by a user-activated push-button
in the application. Both HOT_RESET and PB_ONOFF are de-bounced internally by the TPS65011. Typical debounce time is 56 ms. PB_ONOFF has an internal 1-MΩ pulldown resistor.
PB_ONOFF, BATT_COVER and UVLO events also cause a normal, maskable interrupt to be generated and are
noted in the REGSTATUS register.
7.3.7 Vibrator Driver
The VIB open-drain output is provided to drive a vibrator motor, controlled via the serial interface register
VDCDC2. It has a maximum dropout of 0.5 V at 100-mA load. Typically, an external resistor is required to limit
the motor current, and a freewheel diode to limit the VIB overshoot voltage at turnoff.
7.4 Device Functional Modes
7.4.1 TPS65011 Power States Description
7.4.1.1 State 1: No Power
No batteries are connected to the TPS65011. When main power is applied, the bandgap reference, LDOs, and
UVLO comparator start up. The RESPWRON, PWRFAIL, INT and MPU_RESET signals are held low. When
BATT_COVER goes high (de-bounced internally by the TPS65011), indicating that the battery cover has been
put in place and if VCC > UVLO, the power supplies are ramped in the sequence defined by PS_SEQ.
RESPWRON, PWRFAIL, INT and MPU_RESET are released when the RESPWRON timer has timed out after
tn(RESPWRON) sec. If VCC remains valid and no OVERTEMP condition occurs, then the TPS65011 arrives in State
2: ON. If VCC < UVLO, the TPS65011 keeps the bandgap reference and UVLO comparator active such that
when VCC>UVLO (during battery charge) the supplies are automatically activated.
7.4.1.2
State 2: ON
In this state, TPS65011 is fired up and ready to go. The switching converters can have their output voltages
programmed. The LDOs can be disabled or programmed. TPS65011 can exit this state either due to an
overtemperature condition, by an undervoltage condition at VCC, by BATT_COVER going low, or by the
processor programming low-power mode. State 2 is left temporarily if the user activates the HOT_RESET pin.
7.4.1.3
State 3: Low-Power Mode
This state is entered via the processor setting the ENABLE_LP bit in the serial interface and then raising the
LOW_PWR pin. The TPS65011 actually uses the rising edge of the internal signal formed by a logical AND of
the LOW_PWR and ENABLE LP signals to enter low-power mode. The VMAIN switching converter remains
active, but the VCORE converter may be disabled in low-power mode via the serial interface by setting the
LP_COREOFF bit in the VDCDC2 register. If left enabled, the VCORE voltage is set to the value predefined by
the CORELP0/1 bits in the VDCDC2 register. The LDO1OFF/nSLP and LDO2OFF/nSLP bits in the VREGS1

Device Functional Modes (continued)
register determine whether the LDOs are turned off or put in a reduced power mode (transient speed-up circuitry
disabled in order to minimize quiescent current) in low-power mode. All TPS65011 features remain addressable
via the serial interface. TPS65011 can exit this state either due to an undervoltage condition at VCC, due to
BATT_COVER going low, due to an OVERTEMP condition, by the processor deasserting the LOW_POWER pin,
or by the user activating the HOT_RESET pin or the PB_ONOFF pin.
7.4.1.4
State 4: Shutdown
There are two scenarios for entering this state. The first is from State 1: No Power. As soon as main battery
power is applied, the device automatically enters the WAIT mode.
The second scenario occurs when the device is in ON mode and the processor initiates a shutdown by resetting
the ENABLE SUPPLY bit in the VDCDC1 register (ENABLE_LP must be high), and then raising the LOW_PWR
pin. When this happens, the power rails are ramped down in the predefined sequence, and all circuitry is then
disabled. In this state, the TPS65011 waits for the PB_ONOFF or HOT_RESET pin to be activated before
enabling any of the supply rails. When the PB_ONOFF or HOT_RESET pin is activated, the TPS65011 powers
up the supplies according to the same constraints as at the initial application of power. Complete shutdown is
only achieved by setting the LDO1OFF/nSLP and LDO2OFF/nSLP bits high in the VREGS1 register before
activating the shutdown.
In this case, the I2C interface is deactivated and the registers are reset to their default value after leaving the
WAIT mode.
To enter the WAIT mode when USB or AC is present, the AUA bit (CHCONFIG) must be set. The WAIT
mode is automatically left if Bit 7 in register CHCONFIG is set to 0 (default), and a voltage is present at either the
AC pin or the USB pin in the appropriate range for charging, and the voltage at VCC is above the UVLO
threshold. This feature allows the converters to start up automatically if the device is plugged in for charging.
If all supplies are turned off in WAIT mode, the internal bandgap is switched off, and the internal registers are
reset to their default state when the device returns to ON mode.

The LED2 output can be programmed in the same way as the PG output to blink or to be permanently on or off.
The LED2_ON and LED2_PER registers are used to control the blink rate. For both PG and LED2, the minimum
blink-on time is 10 ms and this can be increased in 127 10-ms steps to 1280 ms. For both PG and LED2, the
minimum blink period is 100 ms and this can be increased in 127 100-ms steps to 12800 ms.

Programming (continued)
7.5.2 Interrupt Management
The open-drain INT pin is used to combine and report all possible conditions via a single pin. Battery and chip
temperature faults, precharge timeout, charge timeout, taper timeout, and termination current are each capable
of setting INT low, i.e., active. INT can also be activated if any of the regulators are below the regulation
threshold. Interrupts can also be generated by any of the GPIO pins programmed to be inputs. These inputs can
be programmed to generate an interrupt either at the rising or falling edge of the input signal. It is possible to
mask an interrupt from any of these conditions individually by setting the appropriate bits in the MASK1, MASK2,
or MASK3 registers. By default, all interrupts are masked. Interrupts are stored in the CHGSTATUS,
REGSTATUS, and DEFGPIO registers in the serial interface. CHGSTATUS and REGSTATUS interrupts are
acknowledged by reading these registers. If a 1 is present in any location, then the TPS65011 automatically sets
the corresponding bit in the ACKINT1 or ACKINT2 registers and releases the INT pin. The ACKINT register
contents are self-clearing when the condition, which caused the interrupt, is removed. The applications processor
should not normally need to access the ACKINT1 or ACKINT2 registers.
Interrupt events are always captured; thus when an interrupt source is unmasked, INT may immediately go active
due to a previous interrupt condition. This can be prevented by first reading the relevant STATUS register before
unmasking the interrupt source.
If an interrupt condition occurs, then the INT pin is set low. The CHGSTATUS, REGSTATUS, and DEFGPIO
registers should be read. Bit positions containing a 1 (or possibly a 0 in DEFGPIO) are noted by the CPU and the
corresponding situation resolved. The reading of the CHGSTATUS and REGSTATUS registers automatically
acknowledges any interrupt condition in those registers and blocks the path to the INT pin from the relevant
bit(s). No interrupt should be missed during the read process since this process starts by latching the contents of
the register before shifting them out at SDAT. Once the contents have been latched (takes a couple of
nanoseconds), the register is free to capture new interrupt conditions. Hence, the probability of missing anything
is, for practical purposes, zero.
The following describes how registers 0x01 (CHGSTATUS) and 0x02 (REGSTATUS) are handled:
• CHGSTATUS(5,0) are positive edge set. Read of set CHGSTATUS(5,0) bits sets ACKINT1(5,0) bits.
• CHGSTATUS(7-6,4-1) are level set. Read of set CHGSTATUS(7-6,4-1) bits sets ACKINT1(7-6,4-1) bits.
• CHGSTATUS(5,0) clear when input signal low, and ACKINT1(5,0) bits are already set.
• CHGSTATUS(7-6,4-1) clear when input signal is low.
• ACKINT1(7-0) clear when CHGSTATUS(7-0) is clear.
• REGSTATUS(7-5) are positive edge set. Read of set REGSTATUS(7-5) bits sets ACKINT2(7-5) bits.
• REGSTATUS(3-0) are level set. Read of set REGSTATUS(3-0) bits sets ACKINT2(3-0) bits.
• REGSTATUS(7-5) clear when input signal low, and ACKINT1(7-5) bit are already set.
• REGSTATUS(3-0) clear when input signal is low.
• ACKINT2(7-0) clear when REGSTATUS(7-0) is clear.
The following describes the function of the 0x05 (ACKINT1) and 0x06 (ACKINT2) registers. These are not
usually written to by the CPU since the TPS65011 internally sets/clears these registers:
• ACKINT1(7:0) - Bit is set when the corresponding CHGSTATUS set bit is read via I2C.
• ACKINT1(7:0) - Bit is cleared when the corresponding CHGSTATUS set bit clears.
• ACKINT2(7:0) - Bit is set when the corresponding REGSTATUS set bit is read via I2C.
• ACKINT2(7:0) - Bit is cleared when the corresponding REGSTATUS set bit clears.
• ACKINT1(7:0) - a bit set masks the corresponding CHGSTATUS bit from INT.
• ACKINT2(7:0) - a bit set masks the corresponding REGSTATUS bit from INT.
The following describes the function of the 0x03 (MASK1), 0x04 (MASK2) and 0x0F (MASK3) registers:
• MASK1(7:0) - a bit set in this register masks CHGSTATUS from INT.
• MASK2(7:0) - a bit set in this register masks REGSTATUS from INT.
• MASK3(7:4) - a bit set in this register detects a rising edge on GPIO.
• MASK3(7:4) - a bit cleared in this register detects a falling edge on GPIO.
• MASK3(3:0) - a bit set in this register clears GPIO Detect signal from INT.

Programming (continued)
GPIO interrupts are located by reading the 0x10 (DEFGPIO) register. The application CPU stores, or can read
from DEFGPIO, which GPIO is set to input or output. This information together with the information on
which edge the interrupt was generated (the CPU either knows this or can read it from MASK3) determines
whether the CPU is looking for a 0 or a 1 in DEFGPIO. A GPIO interrupt is blocked from the INT pin by
setting the relevant MASK3 bit; this must be done by the CPU, there is no auto-acknowledge for the GPIO
interrupts.
7.5.3 Serial Interface
The serial interface is compatible with the standard and fast mode I2C specifications, allowing transfers at up to
400 kHz. The interface adds flexibility to the power supply solution, enabling most functions to be programmed to
new values depending on the instantaneous application requirements and charger status to be monitored.
Register contents remain intact as long as VCC remains above 2 V. The TPS65011 has a 7-bit address with the
LSB set by the IFLSB pin, this allows the connection of two devices with the same address to the same bus. The
6 MSBs are 100100. Attempting to read data from register addresses not listed in this section results in FFh
being read out.
For normal data transfer, DATA is allowed to change only when CLK is low. Changes when CLK is high are
reserved for indicating the start and stop conditions. During data transfer, the data line must remain stable
whenever the clock line is high. There is one clock pulse per bit of data. Each data transfer is initiated with a start
condition and terminated with a stop condition. When addressed, the TPS65011 device generates an
acknowledge bit after the reception of each byte. The master device (microprocessor) must generate an extra
clock pulse that is associated with the acknowledge bit. The TPS65011 device must pull down the DATA line
during the acknowledge clock pulse so that the DATA line is a stable low during the high period of the
acknowledge clock pulse. The DATA line is a stable low during the high period of the acknowledge-related clock
pulse. Setup and hold times must be taken into account. During read operations, a master must signal the end of
data to the slave by not generating an acknowledge bit on the last byte that was clocked out of the slave. In this
case, the slave TPS65011 device must leave the data line high to enable the master to generate the stop
condition.
The I2C interface accepts data as soon as the voltage at VCC is higher than the undervoltage lockout threshold
and one power rail of the converter (main, core, or one of the LDOs) is operating. Therefore, the I2C interface is
not operating after applying the battery voltage as the device automatically enters the WAIT mode with all rails
off.
When the device is in WAIT mode, the I2C registers are reset to their default values if all voltage rails are off. If
the device is in WAIT mode and one power rail is left on, the I2C interface is operating and the registers are not
reset after leaving the WAIT mode.

The ACKINT1 register is internally used to acknowledge any of the interrupts in the corresponding
CHGSTATUS positions. When this is done, the acknowledged interrupt is no longer fed through to the INT
pin and so the INT pin becomes free to indicate the next pending interrupt. If none exists, then the INT pin goes
high, else it will remain low. A 1 at any position in ACKINT1 is automatically cleared when the corresponding
interrupt condition in CHGSTATUS is removed. The application processor should not normally need to access
the ACKINT1 register.

The DEFGPIO register is used to define the GPIO pins to be either input or output.
Bit 7-Bit 4 - IO:
• 0 = sets the corresponding GPIO to be an input.
• 1 = sets the corresponding GPIO to be an output.
Bit 3-Bit 0 - Value GPIO: If a GPIO is programmed to be an output, then the signal output is determined by
the corresponding bit. The output circuit for each GPIO is an open drain NMOS requiring an external pullup
resistor.
• 1 = activates the relevant NMOS, hence forcing a logic low signal at the GPIO pin.
• 0 = turns the open drain transistor OFF, hence the voltage at the GPIO pin is determined by the voltage to
which the pullup resistor is connected.
If a particular GPIO is programmed to be an input, then the contents of the relevant bit in B3-0 is defined by the
logic level at the GPIO pin. A logic low forces a 0 and a logic high forces a 1. If a GPIO is programmed to be an
input, then any attempt to write to the relevant bit in B3-0 is ignored.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The VCORE and VMAIN converter are always enabled in a typical application. The VCORE output voltage can
be disabled or reduced from 1.5 V to a lower, preset voltage under processor control. When the processor enters
the sleep mode, a high signal on the LOW_PWR pin initiates the change.
VCORE typically supplies the digital part of the audio codec. When the processor is in sleep or low-power mode,
the audio codec is powered off, so the VCORE voltage can be programmed to lower voltages without a problem.
A typical audio codec (e.g., TI AIC23) consumes about 20-mA to 30-mA current from the VCORE power supply.
Supply LDO1 from VMAIN as shown in Figure 43. If this is not done, then subsequent to a UVLO, OVERTEMP,
or BATT_COVER = 0 condition, the RESPWRON signal goes high before the VCORE rail has ramped and
stabilized. Therefore, the processor core does not receive a power-on-reset signal.

8.2.1 Design Requirements
Each DC-DC converter requires an external inductor and filter capacitor, capable of sustain the intended current
with an acceptable voltage ripple. LDOs must have external filter capacitors, and LDO1 requires an external
feedback network for regulation. Every input supply rail requires a decoupling capacitor close to the pin, and to
avoid unintended states, logic inputs without internal resistors must not be left floating.

Typical Applications (continued)
8.2.2 Detailed Design Procedure
8.2.2.1 Inductor Selection for the Main and the Core Converter
The main and the core converters in the TPS65011 typically use a 6.2-µH and a 10-µH output inductor,
respectively. Larger or smaller inductor values can be used to optimize the performance of the device for specific
operation conditions. The selected inductor has to be rated for its dc resistance and saturation current. The dc
resistance of the inductance influences directly the efficiency of the converter. Therefore, an inductor with lowest
dc resistance is selected for highest efficiency.
Equation 3 calculates the maximum inductor current under static load conditions. The saturation current of the
inductor must be rated higher than the maximum inductor current as calculated with Equation 3. This is needed
because during heavy load transient, the inductor current rises above the value calculated under Equation 3.

f = Switching frequency (1.25 MHz typical)
L = Inductor value
ΔIL= Peak-to-peak inductor ripple current
ILmax = Maximum inductor current
(4)
The highest inductor current occurs at maximum VI.
Open core inductors have a soft saturation characteristic, and they can usually handle higher inductor currents
versus a comparable shielded inductor.
A more conservative approach is to select the inductor current rating just for the maximum switch current of the
TPS65011 (2 A for the main converter and 0.8 A for the core converter). Keep in mind that the core material from
inductor to inductor differs and has an impact on the efficiency especially at high switching frequencies.

8.2.2.2 Output Capacitor Selection
The advanced fast response voltage mode control scheme of the inductive converters implemented in the
TPS65011 allow the use of small ceramic capacitors with a typical value of 22 µF for the main converter and 10
µF for the core converter without having large output voltage under and overshoots during heavy load transients.
Ceramic capacitors having low ESR values have the lowest output voltage ripple and are recommended. If
required tantalum capacitors with an ESR < 100 ΩR may be used as well.
Refer to Table 6 for recommended components.

If ceramic output capacitors are used, the capacitor RMS ripple current rating always meet the application
requirements. Just for completeness the RMS ripple current is calculated as:

IRMSC(out) = VO ´

At nominal load current, the inductive converters operate in PWM mode and the overall output voltage ripple is
the sum of the voltage spike caused by the output capacitor ESR plus the voltage ripple caused by charging and
discharging the output capacitor:

Where the highest output voltage ripple occurs at the highest input voltage VI.
At light load currents, the converters operate in power save mode and the output voltage ripple is independent of
the output capacitor value. The output voltage ripple is set by the internal comparator thresholds. The typical
output voltage ripple is 1% of the nominal output voltage. If the output voltage for the core converter is
programmed to its lowest voltage of 0.85 V, the output capacitor must be increased to 22 µF for low output
voltage ripple. This is because the current in the inductor decreases slowly during the off-time and further
increases the output voltage even when the PMOS is off. This effect increases with low output voltages.
8.2.2.3 Input Capacitor Selection
A pulsating input current is the nature of the buck converter. Therefore, a low ESR input capacitor is required for
best input voltage filtering. It also minimizes the interference with other circuits caused by high input voltage
spikes. The main converter needs a 22-µF ceramic input capacitor and the core converter a 10-µF ceramic
capacitor. The input capacitor for the main and the core converter can be combined and one 22-µF capacitor can
be used instead, because the two converters operate with a phase shift of 270 degrees. The input capacitor can
be increased without any limit for better input voltage filtering. The VCC pin must be separated from the input for
the main and the core converter. A filter resistor of up to 100 Ω and a 1-µF capacitor is used for decoupling the
VCC pin from switching noise.

9 Power Supply Recommendations
9.1 LDO1 Output Voltage Adjustment
The output voltage of LDO1 is set with a resistor divider at the feedback pin. The sum of the two resistors must
not exceed 1 MΩ to minimize voltage changes due to leakage current into the feedback pin. The output voltage
for LDO1 after start up is the voltage set by the external resistor divider. It can be reprogrammed with the I2C
interface to the three other values defined in the register VREGS1.
10 Layout
10.1 Layout Guidelines
The input capacitors for the DC-DC converters should be placed as close as possible to the VINMAIN,
VINCORE, and VCC pins.
• The inductor of the output filter should be placed as close as possible to the device to provide the shortest
switch node possible, reducing the noise emitted into the system and increasing the efficiency.
• Sense the feedback voltage from the output at the output capacitors to ensure the best DC accuracy.
Feedback must be routed away from noisy sources such as the inductor. If possible route on the opposite
side from the switch node and inductor and place a GND plane between the feedback and the noisy sources
or keep-out underneath them entirely.
• Place the output capacitors as close as possible to the inductor to reduce the feedback loop. This will ensure
best regulation at the feedback point.
• Place the device as close as possible to the most demanding or sensitive load. The output capacitors should
be placed close to the input of the load. This will ensure the best AC performance possible.
• The input and output capacitors for the LDOs should be placed close to the device for best regulation
performance.
• Use vias to connect thermal pad to ground plane.
• TI recommends using the common ground plane for the layout of this device. The AGND can be separated
from the PGND but, a large low parasitic PGND is required to connect the PGNDx pins to the CIN and
external PGND connections. If the AGND and PGND planes are separated, have one connection point to
reference the grounds together. Place this connection point close to the device.
