PIN FUNCTIONS
Pin # Name Description
1 IN Input Supply Pin. IN receives the AC adapter or USB supply voltage.
2
CHG
Open-Drain Charge Status Indicator. This pin is low during charging.
3
ACOK
Open-Drain Input ACOK Indicator. This pin is low if the voltage at the IN pin is between
2.5V and 6.5V.
4
EN
Charger IC Enable. An input “Low” signal at this pin or if the pin is floating will enable the
IC.
5 NC No connection pin
6
Exposed Pad
GND
Ground. Connect exposed pad to the GND pin
7 SS
Soft-Start Timer. Connect this pin to an external capacitor to program the soft-start
startup time using the equation:

8 IBF
Charge Status Threshold Program. Connect this pin to an external resistor to program
the charge termination current or battery full charge current.
9 ISET
Constant Charge Current Program. Connect this pin to an external resistor to program
the charging current in CC Mode.
