The AAT4285 SmartSwitch is a P-channel MOSFET power switch designed for high-side load switching applications. The MOSFET operates from a 3.0V to 13.2V input range making it ideal for applications in single or dual cell Lithium-Ion battery systems. The device has a typical
RDS(ON) of 240mΩ at 12V, allowing a low forward voltagedrop and high current handling capability. The device is aslew rate limited turn-on load switch and is functionallycompatible with the AAT4250 and AAT4280 products,while offering a high operating voltage. The AAT4285features fast load switch turn-on capability of 100μs andoffers a shutdown load discharge circuit to rapidly turn offa load circuit when the switch is disabled. The quiescent
supply current is very low, typically 25μA.
