AAT4618

Current Limited Load Switch

™

SmartSwitch

General Description

Features

The AAT4618 SmartSwitch™ is a member of

AnalogicTech's Application Specific Power MOS-

FET™ (ASPM™) product family. It is a Current

Limited P-channel MOSFET power switch designed

for high-side load-switching applications operating

with inputs ranging from 2.4V to 5.5V which makes it

ideal for 2.5V, 3V and 5V systems. An integrated cur-

rent-limiting circuit protects the input supply from large

currents which potentially cause the supply to fall out

of regulation. In addition, the AAT4618 thermal over-

load protection limits power dissipation and junction

temperatures associated with prolonged periods of

operation in current limit. Due to its low R_DS(ON), the

AAT4618 can be used to control loads that require up

to 500mA even while operating at high ambient tem-

peratures. The ultra fast current-limit response to a

sudden short circuit is a mere 400ns which reduces

the requirements of local supply bypassing. An open

drain FAULT flag signals an over current or over tem-

perature condition after a 4ms timeout. Quiescent

current is a low 10µA and in shutdown mode, the sup-

ply current decreases to less than 1µA.

The AAT4618 is available in a 5 pin SOT-23, and an

8 pin SC70JW specified over a -40 to 85°C temper-

ature range.

The AAT4600 Series is a family of adjustable and

fixed SmartSwitch™ products with a range of current

handling capabilities. Available are single versions

with adjustable current limit (AAT4610, AAT4601) as

well as fixed current limit (AAT4625), and dual ver-

sions with fixed current limit (AAT4626, AAT4670).
