VDD

Supply Voltage Input

TS

Temperature Sense Input. Input from battery temperature monitoring circuit.

STAT1

In charge status, this pin is pulled to high; when charge completed, it’s pulled to

low; and if temperature fault or disable, it’s in high impedance status.

STAT2

In charge status, this pin is pulled to low; when charge completed, it’s pulled to

high; and if temperature fault or disable, it’s in high impedance status.

GND

Gound

CC

Charge Control Output. Current output to drive on external PNP transistor or

P-Channel MOSFET for current and voltage regulation

CS

Current Sense Input. Charge current is sensed according to the voltage drop

from supply voltage to this pin

BATT

Battery voltage input. Input directly from battery voltage.
