AAT4608 Current Limited Load Switch in a SOT23 Package

The AAT4608 SmartSwitch is a member of Skyworks' Application Specific Power MOSFET™ (ASPM™) product family. It is a current limited P-channel MOSFET power switch designed for high-side load switching applications. This switch operates with inputs ranging from 2.7V 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. The AAT4608 is also protected from thermal overload which limits power dissipation and junction temperatures. It can be used to control loads that require up to 1A. Current limit threshold is programmed with a resistor from SET to ground. The quiescent supply current is typically a low 15μA max. The AAT4608 is available in a Pb-free, 5-pin SOT23 package, and is specified over the -40°C to +85°C temperature range.
