Input power, connect to external DC supply. Connect external 1µF (minimum) to GND
Ground terminal
These pins may have internal circuits used for test purposes. Do not make any external
connections at these pins for normal operation.
Open-drain output, device status. FAULTB = LO indicates that the input FET has been turned
off due to input over-voltage or input over-current conditions, or because the battery voltage is
outside safe limits.
Chip enable input. Active low. When ENB = HI, the input FET is off. Internally pulled down.
Battery voltage sense input. Connect to pack positive terminal through a resistor.
Input over-current threshold programming. Connect a resistor to GND to set the over-current
threshold.
Output terminal to the charging system. Connect external 1µF capacitor (minimum) to GND
There is an internal electrical connection between the exposed thermal pad and the GND pin
of the device. The thermal pad must be connected to the same potential as the GND pin on
the printed circuit board. Do not use the thermal pad as the primary ground input for the
device. GND pin must be connected to ground at all times.
