AAT4625

General Description The AAT4625 SmartSwitch is part of Skyworks' Application Specific Power MOSFET™ (ASPM™) product family. It is a 1.0A 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 load current which may cause the supply to fall out of regulation. The AAT4625 is also protected from thermal overload which limits power dissipation and junction temperatures. The current limit threshold is factory programmed at 1.5A, with a maximum of 2.0A. The quiescent supply current is typically a low 16μA. In shutdown mode, the supply current decreases to less than 1μA. The AAT4625 is available in Pb-free, 8-pin SOP or MSOP packages, and is specified over the -40°C to +85°C temperature range. The AAT4600 series is a family of adjustable and fixed Smar...
