1 / 10 page  SmartSwitch™ AAT4611 Current Limited Load Switch in SOT23 Package 4611.2006.09.1.4 1 General Description The AAT4611 SmartSwitch is a current limited P- channel MOSFET power switch designed for high- side load switching applications. This switch oper- ates 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 AAT4611 is also pro- tected 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 AAT4611 is available in a Pb-free 5-pin SOT23 package and is specified over the -40°C to +85°C temperature range.
