The AAT4626 SmartSwitch is part of AnalogicTech’s ApplicaTIon Specific Power MOSFET™ (ASPM™) product family. It is a dual-channel 500mA 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 changes in loadcurrent which may cause the supply to fall out of regulaTIon. The AAT4626 is also protected from thermal overload which limits power dissipation and junction temperatures.The current limit threshold is factory programmed at 1.0A, with a maximum of 1.5A. The quiescent supply current is typically a low 20μA. In shutdown mode, the supply current decreases to less than 1μA.
