AAT4280A

Slew Rate Controlled Load Switch

Skyworks Solutions 

General Description

The AAT4280A SmartSwitch is a member of Skyworks'

Application Specific Power MOSFET (ASPM™) product

family. The AAT4280A is a P-channel MOSFET power

switch designed for high-side load switching applications.

The device has a typical RDS(ON) of 80mW, allowing

increased load switch power handling capacity. The device

is available in three different versions with flexible turn-on

and turn-off characteristics - from very fast to slew rate

limited. The standard AAT4280A (-1) version has a slew

rate limited turn-on load switch and is functionally com-

patible with the AAT4250 device, while offering superior

RDS(ON) characteristics. The AAT4280A (-2) version fea-

tures fast load switch turn-on capabilities, typically less

than 500ns turn-on and 3µs turn-off times. The AAT4280A

(-3) variation offers a shutdown load discharge circuit to

rapidly turn off a load circuit when the switch is disabled.

The AAT4280A (-4) version features the slowest load

switch turn-on capability, typically greater than 4.0ms

turn-on time. All AAT4280A load switch versions operate

with an input voltage ranging from 1.5V to 5.5V, making

them ideal for both 3V and 5V systems. Input logic levels

are TTL and 2.5V to 5V CMOS compatible. The quiescent

supply current is very low, typically 25nA.

The AAT4280A is available in the Pb-free 8-pin SC70JW,

6-pin SOT23, and WLCSP-5 packages and is specified

over the -40°C to +85°C temperature range.
