GND

Power Supply Ground Pin.

5

STB

Short-to-Battery Indicator Output Pin. A logic low indicates an overvoltage condition (short-to-battery), whereas a

logic high indicates normal operation. An open-drain configuration requires external pull-up resistor.

Positive Power Supply Pin. Bypass this pin with a 0.1 µF capacitor to ground.

EPAD

Exposed Pad. The exposed pad is located on the bottom side of the package. The pad is not connected electrically

but should be soldered to a metalized area on the printed circuit board (PCB) to minimize thermal resistance.
