The AAT4280A SmartSwitch is a member of AnalogicTech’s 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 80mΩ, 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. 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 4.0msturn-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 levelsare TTL and 2.5V to 5V CMOS compatible. The quiescent
supply current is very low, typically 25nA.
