The AAT4282A SmartSwitchTM is a member of AnalogicTech's Application Specific Power MOSFETTM (ASPMTM) product family. The AAT4282A is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 60m, allowing increased load switch current handling capacity with a low forward voltage drop. 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 4282A (-1) version has a slew-rate limited turn-on load switch. The AAT4282A (-2) version features fast turn-on capability, typically less than 500ns turn-on and 3s turn-off times. The AAT4282A (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. An additional feature is a slew-rate selector pin which can switch between fast and slow slew rate.
