The AAT4610A SmartSwitch is a member of AnalogicTech 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 2.4V 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. The AAT4610A 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 9A. In shutdown mode, the supply current decreases to less than 1A. The AAT4610A is available in a 5-pin SOT23 or an 8-pin SC70JW package specified over the -40 to +85C temperature range.
