The AAT4626 SmartSwitch™ is part of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. It is a dualchannel 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 3Vand 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 AAT4626 is also protected from thermal overload which limits powerdissipation 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 20A. In shutdown mode, the supply current decreases to less than 1A.
The AAT4626 is available in 8 pin SOP or TSSOP specified over a -40 to 85 temperature range.
The AAT4600 Series is a family of adjustable and fixed SmartSwitch™ products with a range of current 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 also available.
