APL3546A

Power -Distribution Switches with Soft Start

General Description

Features

The APL3546A is a power-distribution switch with some

78mW High Side MOSFET

protection functions. The device incorporates a 78mW N-

Soft Start Time Programmable by External

Capacitor

channel MOSFET power switch that is controlled by an

enable logic pin and has a SS pin dedicated to soft start

ramp-up rate control that can be used in application where

the inrush current is concerned.

Wide Supply Voltage Range: 4.5V to 24V

Current Limit Protections

Under Voltage Lockout Protection

Over-temperature Protection

Logic Level Enable Input

The device integrates some protection features, includ-

ing current limit protection, over-temperature protection,

UVLO and current limit setting. The current limit protec-

tion can protect down-stream devices from catastrophic

failure by limiting the output current at current limit thresh-

old during over-load or short circuit events. The over-tem-

perature protection function shuts down IC when the junc-

tion temperature rises beyond 150^oC. The UVLO function

keeps the power switch in off state until there is a valid

input voltage present. The current limit can be set by con-

necting resistor from the current limit adjustable pin ISET

to ground.
