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 0.01F 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.
EN
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.
