AAT4625 USB Single-Channel Power Switch
The AAT4625 SmartSwitch is a member of Skyworks' Application Specific Power MOSFET™ (ASPM™) product family. It is a current limited P-channel MOSFET power switch designed for high-side load switching applications operating with inputs ranging from 2.4V to 5.5V, making it ideal for 2.5V, 3V, and 5V systems. An integrated current-limiting circuit protects the input supply from large currents which may cause the supply to fall out of regulation. In addition, the AAT4625 thermal overload protection limits power dissipation and junction temperatures associated with prolonged periods of operation in current limit. Due to its low RDS(ON), the AAT4625 can be used to control loads that require up to factory preset 400mA, 500mA, or 1A. The ultra-fast current limit response to a sudden short circuit is a mere 400ns which reduces the requirements of local supply bypassing. An open drain FAULT flag signals an over-current or overtemperature condition after a 4ms timeout. Quiescent current is a low 10μA and the supply current decreases to less than 1μA in shutdown mode. The AAT4625 is available in a Pb-free 5-pin SOT-23 or a 8-pin SC70JW package and is specified over the -40°C to +85°C temperature range. The AAT4600 series is a family of adjustable and fixed voltage SmartSwitch products with a range of current handling capabilities. Single versions with adjustable current limit (AAT4610, AAT4601) or fixed current limit (AAT4625) are available, as well as dual versions with fixed current limit (AAT4626, AAT4670).
