The AAT4614 SmartSwitch is a current limited P-channel MOSFET power switch designed for high side load switching
applications. This switch operates with inputs ranging from 2.4V to 5.5V, making it ideal for both 3V and 5V systems. An
integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of
regulation. Reverse current blocking is provided to protect the load switch from reverse current potentials while the device is
shutdown. The AAT4614 is also protected from thermal overload which is limited by power dissipation and junction tempera-
tures. Current limit threshold is programmed with a resistor from SET to ground and has been adjusted for levels up to 1.1A.
