Function

Battery voltage level sense input.

Current sense input.

Not connected.

2X battery trickle charge control input. Connect this pin to VSS to

double the battery trickle charge current. Leave this pin floating for

normal trickle charge current (10% of full charge current). To enter

microcontroller fast-read status, pull this pin high during power-up.

Battery charge control output.

Common ground connection.

Battery charge status output. Connect an LED in series with 2.2kΩ

from STAT to VP to monitor battery charge state.

Power supply input pin.

Battery temperature sense input.
