AAT4610IGV-1-T1

Current Limited Load Switch General Description The AAT4610 SmartSwitch is a current limited Pchannel MOSFET power switch designed for highside 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 AAT4610 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. In shutdown mode, the supply current decreases to less than 1µA. The AAT4610 is available in a Pb-free 5-pin SOT23 package and is specified over the -40°C to +85°C temperature range.
