AAT4625

USB Single-Channel Power Switch

™

SmartSwitch

General Description

Features

The AAT4625 SmartSwitch™ is part of

AnalogicTech's Application Specific Power

MOSFET™ (ASPM™) product family. It is a 1.0A

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 AAT4625 is also protected from thermal over-

load which limits power dissipation and junction

temperatures. The current limit threshold is factory

programmed at 1.5A, with a maximum of 2.0A. The

quiescent supply current is typically a low 16µA. 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 cur-

rent handling capabilities. Single versions with

adjustable current limit (AAT4601) or fixed current

limit (AAT4625) as well as dual versions with fixed

current limit (AAT4626) are available.
