The AAT4282A SmartSwitch? is a member of AnalogicTech’sApplication Specific Power MOSFET? (ASPM?) productfamily. 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 60mΩ, allowingincreased load switch current handling capacity with a lowforward voltage drop. The device is available in three differentversions with flexible turn-on and turn-off characteristics– from very fast to slew-rate limited. The standard4282A (-1) version has a slew-rate limited turn-onload switch. The AAT4282A (-2) version features fastturn-on capability, typically less than 500ns turn-on and3μs turn-off times. The AAT4282A (-3) variation offers ashutdown load discharge circuit to rapidly turn off a loadcircuit when the switch is disabled. An additional featureis a slew-rate selector pin which can switch between fastand slow slew rate.
