FUNCTIONAL PIN DESCRIPTION

Name

Description

BAT

Charging Output - This pin is wired to the positive terminal of the battery. (The negative battery terminal is wired

to GND.)

CCP

Charge Current Programming Pin - A resistor (Rccp) is connected between this pin and GND. See application

section for programming information.

CMP

Compensation Pin – Apply a 0.01µF capacitor between CMP and VIN pins.

CTP

Charge Termination Programming Pin – A resistor (Rctp) is connected between this pin and GND See

application section for programming information.

Enable - Applying a TTL compatible Hi signal enables the charger, a Low signal disables the charger and puts it

in sleep mode.

GND

Common Ground.

STAT

Status - This pin is a logic low level when the battery is being charged. Pin can sink up to 5mA.

VIN

Voltage Input – Supply Voltage. Must be greater than VBAT to charge.
