General Description
The AAT4252A SmartSwitch™ is a dual P-channel MOSFET power switch designed for high-side loadswitching applications. Each MOSFET has a typical RDS(ON) of 105mΩ, 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.
