Pin Description

Pin

Name

Description

1

STAT1

Open-Drain Charge Status Output. When the battery is charging, the STAT pin is pulled low by an

internal N-channel MOSFET. When the charge cycle is completed, the pin is pulled High.

2

GND

Ground.

3

BAT

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

to 4.2V. An internal precision resistor divider from this pin sets the float voltage which is

disconnected in shutdown mode.

4

VCC

Positive Input Supply Voltage. It provides power to the charger. VCC can range from 4.35V to

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

5

STAT2

Open-Drain Charge Status Output. When the battery is charging, the STAT pin is pulled High by

an internal N-channel MOSFET. When the charge cycle is completed, the pin is pulled Low.

6

PROG

Charge Current Program, Charge Current Monitor and Shutdown Pin. The charge current is

programmed by connecting a 1% resistor to ground(RPROG).
