NAME

DESCRIPTION

OUT5

LDO5 Output. Capable of delivering up to 150mA of output current. Output is discharged to

ground with 1kΩ when disabled.

OUT3

LDO3 Output. Capable of delivering up to 100mA of output current. Output is discharged to

ground with 1kΩ when disabled.

IN1

Input Supply to LDO1, LDO3, LDO5, and LDO7. Connect to BAT and IN2.

nON

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 15kΩ pull-up resistor.

Ground. Connect G and GP together at a single point place as close to the IC as possible.

HF_PWR

Hands Free Input. A high level indicates availability of hands free input. This pin is internally

pulled down to G via a 200kΩ resistor. Connect to a 0.1µF capacitor to G to achieve TBDkV

(typ) ESD protection.

VBUCK

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.

33, 34

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.

No Connect. Not internally connected.

nACOK

CHG_IN Active Low Status Output. nACOK is asserted low when VCHG_IN > 4.0V.

nENCHG

Charge Enable Active Low Input. Drive low or leave floating to enable the charger. Drive high to

disable the charger. This pin has an internal 200kΩ pull-down resistor.

BATID

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.

VICHG

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.

Exposed Pad. Must be soldered to ground on the PCB.
