AAT4280A - Slew Rate Controlled Load Switch

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.

Key Features

  • 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, t.

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 compatible with the AAT4250 device, while offering superior RDS(ON) characteristics. The AAT4280A (-2) version features fast load switch turn-on capabilities, typically less than 500ns turn-on and 3µs turn-off times.
