DESCRIPTION
VIN is the input power source.
FAULT is an open-drain output indicating fault status. This pin is pulled to LOW under any fault
conditions.
STATUS is an open-drain output indicating charging and inhibit states. The STATUS pin is pulled LOW
when the charger is charging a battery.
The TIME pin determines the oscillation period by connecting a timing capacitor between this pin and
GND. The oscillator also provides a time reference for the charger.
GND is the connection to system ground.
EN is the enable logic input. Connect the EN pin to LOW to disable the charger or leave it floating to
enable the charger.
The V2P8 is a 2.8V reference voltage output. The 2.8V is present when VIN is above 3.4V typical. If VIN
falls below 2.4V typical the V2P8 output will be at 0V.
This is the programming input for the constant charging current.
TEMP is the input for an external NTC thermistor. The TEMP pin is also used for battery removal
detection.
VBAT is the connection to the battery.
The metal slug on the bottom surface of the package is floating. Tie to system GND.
