AAT4280 - Slew Rate Controlled Load Switch

Download the AAT4280 datasheet PDF. This datasheet also covers the AAT variant, as both devices belong to the same slew rate controlled load switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The AAT4280 SmartSwitch is a P-channel MOSFET power switch designed for high-side load switching applications.

The P-channel MOSFET device has a typical RDS(ON) of 80mΩ, allowing increased load switch power handling capacity.

Key Features

  • fast load switch turn on capabilities, typically less than 500ns turn on and 3µs turn off times. The AAT4280 (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. All AAT4280 load switch versions operate with an input voltage ranging from 1.8V to 5.5V, making them ideal for both 3V and 5V systems. The AAT4280 also features an under-voltage lockout which turns the switch off when an input under-voltage condition exists. Input logic.

General Description The AAT4280 SmartSwitch is a P-channel MOSFET power switch designed for high-side load switching applications. The P-channel MOSFET device has a typical RDS(ON) of 80mΩ, allowing increased load switch power handling capacity. This device is available in three different versions with flexible turn on and off characteristics from very fast to slew rate limited. The standard AAT4280 (-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 AAT4280 (-2) version features fast load switch turn on capabilities, typically less than 500ns turn on and 3µs turn off times.
