The AAT4252A SmartSwitch™ is a dual P-channel MOSFETpower switch designed for high-side load-switching applicaTIons.Each MOSFET has a typical RDS(ON) of 105mΩ,allowing increased load switch current handling capacitywith a low forward voltage drop. The device is availablein three different versions with flexible turn-on and turnoffcharacterisTIcs–from very fast to slew-rate limited.The standard 4252A (-1) version has a slew-rate limitedturn-on load switch. The AAT4252A (-2) version featuresa fast turn-on capabiliTIes, typically less than 500ns turnonand 3μs turn-off TImes. The AAT4252A (-3) variationoffers a shutdown load discharge circuit to rapidly turnoffa load circuit when the switch is disabled. An additionalfeature is a slew-rate selector pin which can switchbetween fast and slow slew rate.
