IC enable input. Drive this pin to logic LO to enable the charger. Drive this pin to logic HI to disable
the charger. Do not leave this pin floating.
Analog ground.
Charge current programing pin. Connect a resistor between this pin and the GND pin to set the
charge current.
End-of-charge current programing pin. Connect a resistor between this pin and the GND pin to set
the end-of-charge current.

capacitor is needed at this pin.
Input current sense positive connection pin. Connector a sense resistor from this pin the CISN.
Input current sense negative connection pin. Connector a sense resistor from this pin the CISP.
High side NMOS FET gate drive supply pin. Connect a Schottky diode from VBIAS to this pin, and a
0.1mF capacitor to AGND, as shown in the Typical Application Circuits.
Internal 5V regulator output. Connect a 1μF ceramic capacitor from this pin to AGND.
Input for an external NTC thermistor for battery temperature monitoring.
The TIME pin sets the oscillation period by connecting a timing capacitor between this pin and GND.
The oscillator also provides a time reference for the charger. The timer function can be disabled by
connecting the TIME pin to GND. If the timer is disabled, there will be no timeout function for any
operation mode including trickle charge and fast charge modes.

Exposed pad. Connect to GND electrically. Thermally, connect as much as possible copper to this pad
either on the component layer or other layers through thermal vias to enhance the thermal
performance.
Open-drain indication pin. In conjunction with STAT1 this pin provides a unique indication for each
