Current Limited Load Switch in SOT-23 Package

™

SmartSwitch

General Description

Features

The AAT4608 SmartSwitch™ is a member of

AnalogicTech's Application Specific Power

MOSFET™ (ASPM™) product family. It is a Current

Limited P-channel MOSFET power switch designed

for high-side load-switching applications. This switch

operates with inputs ranging from 2.7V to 5.5V, mak-

ing it ideal for both 3V and 5V systems. An inte-

grated current-limiting circuit protects the input sup-

ply against large currents which may cause the sup-

ply to fall out of regulation. The AAT4608 is also pro-

tected from thermal overload which limits power dis-

sipation and junction temperatures. It can be used

to control loads that require up to 1 A. Current limit

threshold is programmed with a resistor from SET to

ground. The quiescent supply current is typically a

low 15µA max.
