AAT4610A

Current Limited Load Switch

™

SmartSwitch

General Description

Features

The AAT4610A SmartSwitch is a current limited P-

channel MOSFET power switch designed for high-

side load switching applications. This switch oper-

ates with inputs ranging from 2.4V to 5.5V, making it

ideal for both 3V and 5V systems. An integrated

current-limiting circuit protects the input supply

against large currents which may cause the supply

to fall out of regulation. The AAT4610A 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 1A. Current limit

threshold is programmed with a resistor from SET to

ground. The quiescent supply current is typically a

low 9µA. In shutdown mode, the supply current

decreases to less than 1µA.
