AAT4626 T4626USB Dual-Channel Power Switch
The AAT4626 SmartSwitch is part of Skyworks' 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 load current which may cause the supply to fall out of regula- tion. The AAT4626 is also protected from thermal over- load which limits power dissipation and junction tem- peratures. The current limit threshold is factory pro- grammed at 1.0A, with a maximum of 1.5A. The quies- cent supply current is typically a low 20μA. In shutdown mode, the supply current decreases to less than 1μA. The AAT4626 is available in a Pb-free, 8-pin SOP pack- age and is specified over the -40°C to +85°C tempera- ture range. The AAT4600 series is a family of adjustable and fixed SmartSwitch products with a range of current handling capabilities. Single versions are available with adjustable current limit (AAT4601) or fixed current limit (AAT4626), as well as dual versions with fixed current limit (AAT4626).
