Function
Battery charging and sensing.
Adapter input.
Ground connection.
Enable pin. Logic high enables the IC..
Adapter present indicator. This pin is open drain until ADP pin reaches
threshold.
Battery temperature sense input.
Status report to microcontroller via serial interface: open drain.
Battery charge status indicator pin to drive an LED: active low, open drain.
Battery charge status indicator pin to drive an LED: active low, open drain.
Timing capacitor to adjust internal watchdog timer. Set maximum charge
time for adapter powered trickle, CC, and CV charge modes. If timing
function is not needed, terminate this pin to ground.
No connection.
Use resistor at this pin to set adapter charging current.
Exposed paddle (bottom); connect to GND directly beneath package.
