AAT4601

1.5A Current Limited P-Channel Switch

™

SmartSwitch

General Description

Features

The AAT4601 SmartSwitch™ is part of

AnalogicTech's Application Specific Power

MOSFET™ (ASPM™) product family. It is a 1.5A

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 sys-

tems. An integrated current-limiting circuit protects

the input supply against large changes in load cur-

rent which could cause the supply to fall out of reg-

ulation. The AAT4601 has protection from thermal

overload which limits power dissipation and junc-

tion temperatures. The maximum current limit

level is 1.5A; the actual threshold is programmed

with a resistor from the SET pin to ground. The qui-

escent supply current is typically 12µA. In shut-

down mode, the supply current decreases to less

than 1µA.
