DATA SHEET AAT4625 USB Single-Channel Power Switch General Description Features The AAT4625 SmartSwitch is part of Skyworks Application Compliant with USB 1.1 and 2.0 Specifications Specific Power MOSFET (ASPM) product family. It is 2.7V to 5.5V Input Voltage Range a 1.0A current limited P-channel MOSFET power switch 1.0A Minimum Continuous Current designed for high-side load-switching applications. This 2.0A Maximum Current Limit switch operates with inputs ranging from 2.7V to 5.5V, 60m Typical R DS(ON) making it ideal for both 3V and 5V systems. An inte- Low Quiescent Current: grated current-limiting circuit protects the input supply Typically 16A against large changes in load current which may cause 1A Maximum with Switch Off the supply to fall out of regulation. The AAT4625 is also Thermal Shutdown protected from thermal overload which limits power dis- Slew Rate Limited Turn On sipation and junction temperatures. The current limit Fault Flag with 10ms Blanking threshold is factory programmed at 1.5A, with a maxi- Under-Voltage Lockout (UVLO) mum of 2.0A. The quiescent supply current is typically a Temperature Range: -40C to +85C low 16 A. In shutdown mode, the supply current UL ApprovedFile No. E217765 decreases to less than 1A. 8-Pin SOP or MSOP Package The AAT4625 is available in Pb-free, 8-pin SOP or MSOP packages, and is specified over the -40C to +85C tem- Applications perature range. General Purpose Power Switching The AAT4600 series is a family of adjustable and fixed Hot Swap Supplies SmartSwitch products with a range of current handling Notebook Computers capabilities. Single versions with adjustable current limit USB Ports and Peripherals (AAT4601) or fixed current limit (AAT4625) as well as dual versions with fixed current limit (AAT4626) are available.
