General Description

The AAT4625 SmartSwitch is part of AnalogicTech's

Application Specific Power MOSFET™ (ASPM™)

product family. It is a 1.0A current limited P-chan-

nel 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.

AAT4625 is also protected from thermal overload

which limits power dissipation and junction temper-

atures. The current limit threshold is factory pro-

grammed 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 AAT4625 is available in Pb-free, 8-pin SOP,

TSSOP, or MSOP packages, and is specified over

the -40°C to +85°C temperature range.

The AAT4600 series is a family of adjustable and

fixed SmartSwitch products with a range of current

handling

adjustable current limit (AAT4601) or fixed current

limit (AAT4625) as well as dual versions with fixed

current limit (AAT4626) are available.
