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 2.2kâ¦
from STAT to VP to monitor battery charge state.
Power supply input pin.
Battery temperature sense input.
