Input: Power switch and logic supply input.
Ground: Input and output return pin.
Enable (Input): Logic compatible, enable control input that allows switch turn-on/off.
Do not leave the EN pin floating.
Fault Status Flag (Output): Active-low, open-drain output. A logic low state
indicates an overcurrent or thermal shutdown condition. An overcurrent condition
must last longer than tFAULT/ to assert FAULT/. A pull-up resistor (10kΩ
recommended) to an external supply is required.
Current Limit Set: Current limit adjust setting. Connect a resistor from this pin to
GND to set the current limit, but do not leave the ILIMIT pin floating.
Switch Output: Power switch output.
Exposed Pad: Exposed pad on bottom of package. Connect to electrical ground for
optimum thermal dissipation.
