Parameter
Input Supply Pin. Provides power to the charger, V
bypassed with at least a 4.7 F capacitor.
Charge Status Output Pin 1. This pin is an active-high, open-drain output pin.
Charging Current Setting Pin. Connecting a resistor from this pin to GND set the fast-charge
current when the VIN is powering the charger.
Ground.
Charging Enable/Disable Control Pin. Drive EN high to begin charging, and EN low to stop
charging.
External Thermistor Connection Pin. THRM pauses charging when an externally connected
thermistor (10k
disables this function.
3V Reference Voltage Output Pin. Sources up to 500 A to bias the external thermistor. Bypass
with 0.1 F to GND. REF loading does not affect BATT regulation accuracy.
Charge Status Output Pin 2. This pin is an active-high, open-drain output pin.
Bias Supply Pin for Internal Circuitry. Bypass with a 2.2 F capacitor to GND.
Charger Output Pin. Connect this pin to the positive terminal of a Li+ battery.
Exposed Pad. Connect a large ground plane for maximum package heat dissipation. Connect
directly to GND under the IC.
