Input: Power switch and logic supply input.
Ground: Input and output return pin.
Enable (Input): Logic compatible, enable control input that allows turn-on/-off of
the switch. Do not leave the EN pin floating.
Fault Status Flag (Output): Active-low, open-drain output. A logic LOW state
indicates an over current or thermal shutdown condition. An over current condition
must last longer than tFAULT/ in order to assert FAULT/. A pull-up resistor (10kΩ
recommended) to an external supply is required.
Slew Rate Control: Adjustable soft-start input. Adding a small value capacitor from
CSLEW to VIN slows the turn-on time of the power MOSFET.
Switch Output: Power switch output.
Exposed Pad: Exposed pad on bottom side of package. Connect to electrical
ground for optimum thermal dissipation.
