NAME
DESCRIPTION
LDO1 Output. Capable of delivering up to 300mA of output current. Output has high impedance
when disabled.
22
OUT1
LDO7 Output. Capable of delivering up to 250mA of output current. Output has high impedance
when disabled.
23
24
OUT7
OUT5
LDO5 Output. Capable of delivering up to 150mA of output current. Output is discharged to
ground with 1kꢀ when disabled.
LDO3 Output. Capable of delivering up to 100mA of output current. Output has high impedance
when disabled.

OUT3
IN1
Input Supply to LDO1, LDO3, LDO5, and LDO7. Connect to BAT and IN2.
Push Button Active Low Open Drain Output. When PWR_ON is low, nON is open drain. When
PWR_ON is high or when in shutdown, nON is asserted low. This output is internally connected
to OUT1 via a 15kꢀ pull-up resistor.

G
Ground. Connect G and GP together at a single point place as close to the IC as possible.
Hands Free Input. A high level indicates availability of hands free input. This pin is internally
HF_PWR pulled down to G via a 200kꢀ resistor. Connect to a 0.1µF capacitor to G to achieve TBDkV
(typ) ESD protection.
Output Feedback Sense for REG. Connect this pin directly to the output node to connect the
internal feedback network to the output voltage.

No Connect. Not internally connected.
Power Input for REG. Connect to BAT, IN1, and IN2. Bypass to GP with a high quality ceramic
capacitor placed as close as possible to the IC.

NC
Switching Node Output for REG. Connect this pin to the switching end of the inductor.
Power Ground for REG. Connect G and GP together at a single point place as close to the IC
as possible.

37
No Connect. Not internally connected.
nACOK CHG_IN Active Low Status Output. nACOK is asserted low when VCHG_IN > 4.0V.
Charge Enable Active Low Input. Drive low or leave floating to enable the charger. Drive high to
nENCHG

disable the charger. This pin has an internal 200kꢀ pull-down resistor.
Battery ID pin to detect the presence of the battery. When the battery is present, the voltage at
this pin is lower than 2V, otherwise, it is higher than 2V.
BATID
Charge Current Monitor. The voltage at this pin is proportional to the charger current, with a
gain of 2.47mV/mA. This output becomes high impedance in shutdown.
