TERMINAL

I/O DESCRIPTION

NAME NO.

CHARGER SECTION

Open-drain output. Active low when UVLO comparator indicates low VBAT condition or

PWRFAIL 34 O when shutdown is about to occur due to an overtemperature condition or when the battery

cover is removed (BATT_COVER has gone low).

Indicates a charge fault or termination, or if any of the regulator outputs are below the lower

INT 35 O
