Pin Function
Enable (Input): Logic-compatible enable input.
Fault Flag (Output): Active-low, open-drain output. Indicates overcurrent, UVLO,
and thermal shutdown.
Ground
Not internally connected.
Supply Input: Input to the power switch and the supply voltage for the IC.
Switch Output: Output of the high side switch. Pins 6 and 8 must be tied together.
