Pin Descriptions

Pin #

Name

Type

Function

Output of over-voltage protection (OVP) stage and input to battery charger. Decouple to GND

with 2.2μF capacitor.

INCHR

I/O

Input from USB port or AC adapter.

4.9V/30mA LDO output through OVP device. Bypass to GND with 2.2μF capacitor.

Over-voltage fault ﬂag, open drain, active low.

LDOOUT

OVPFLG

STAT

Charge status indicator pin, open drain, active low.

MODE selection pin (internal connect with a 200kꢀ pull-up resistor to INCHR). Factory default

at 10% termination current if MODE is open or connect to INCHR. Continues to charge if

MODE is connect to GND.

I/O

Power ground.

Active low enable pin (internal connect with a 200kꢀ pull-down resistor).

Connect R_SETresistor here to set adaptor or USB charging current.

Internally connected through 100kꢀ resistor to GND. Leave this pin open.

Battery voltage remote sense input.

Connect to Li-Ion battery.

Exposed paddle (bottom); The exposed thermal pad (EP) should be connected to board

ground plane and pin 7. The ground plane should include a large exposed copper pad under

the package for thermal dissipation (see package outline).
