1 / 8 page  SmartSwitch™ AAT4625 USB Single-Channel Power Switch 4625.2002.1.0.93 1 General Description The AAT4625 SmartSwitch™ is part of AnalogicTech's 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 over- load 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 8 pin SOP or TSSOP and is specified over a -40 to 85°C temperature range. The AAT4600 Series is a family of adjustable and fixed SmartSwitch™ products with a range of cur- rent handling capabilities. Single versions with adjustable current limit (AAT4601) or fixed current limit (AAT4625) as well as dual versions with fixed current limit (AAT4626) are available.
