USB Dual-Channel Power Switch

™

SmartSwitch

General Description

Features

The AAT4626 SmartSwitch is part of AnalogicTech's

Application Specific Power MOSFET™ (ASPM™)

product family. It is a dual-channel 500mA 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, making it ideal for both 3V and 5V systems.

An integrated current-limiting circuit protects the

input supply against large changes in load current

which may cause the supply to fall out of regulation.

The AAT4626 is also protected from thermal over-

load which limits power dissipation and junction

temperatures. The current limit threshold is factory

programmed at 1.0A, with a maximum of 1.5A. The

quiescent supply current is typically a low 20µA. In

shutdown mode, the supply current decreases to

less than 1µA.

The AAT4600 series is a family of adjustable and

fixed SmartSwitch products with a range of current

handling capabilities. Single versions are available

with adjustable current limit (AAT4601) or fixed cur-

rent limit (AAT4625), as well as dual versions with

fixed current limit (AAT4626).
