General Description

The OCP0502A is a P-channel MOSFET power

distribution switch which intended for high-side

load-switching applications. The device integrates

adjustable current limit function with an external

resistor from ISET pin to ground.

The OCP0502A also features fast short-circuit

response, under voltage lockout, over temperature

protection, reverse current protection, QOD and so

on.
