PIN CONFIGURATION

PIN DESCRIPTION

PIN NO.

PIN NAME

DESCRIPTION

CHRG

Open-Drain Charge Status Output. When the battery is charging, the CHRG pin is

pulled low by an internal N-channel MOSFET. When the charge cycle is completed, a

weak pull-down of approximately 20uA is connected to the CHRG pin, indicating an “AC

present” condition.

GND

Ground.

BAT

Charge Current Output. Provides charge current to the battery and regulates the final

float voltage to 4.2V.

VCC

Positive Input Supply Voltage. Provides power to the charger. VCC can range from

4.25V to 6.5V and should be bypassed with at least a 1μF capacitor.

PROG

Charge Current Program, Charge Current Monitor and Shutdown Pin.
