DATA SHEET AAT4282B Slew Rate Controlled Load Switch General Description Features The AAT4282B SmartSwitch is a member of Skyworks V Range: 1.5V to 6.5V IN Application Specific Power MOSFET (ASPM) product Low R DS(ON) family. The AAT4282B is a dual P-channel MOSFET power 67m Typical 5V switch designed for high-side load-switching applications. 125m Typical 1.8V Each MOSFET has a typical R of 67m, allowing Slew Rate Turn-On Time DS(ON) increased load switch current handling capacity with a low 750s - Slow (FAST = Low) forward voltage drop. The AAT4282B offers a shutdown 65s - Fast (FAST = High) load discharge circuit to rapidly turn off a load circuit Fast Shutdown Load Discharge Option when the switch is disabled. A slew-rate selector pin can Low Quiescent Current switch between fast and slow slew rate. 40nA Typical TTL/CMOS Input Logic Level The AAT4282B load switch operates from 1.5V up to Temperature Range -40C to 85C 6.5V, making it ideal for both 3V and 5V systems. Input TDFN22-8 Package logic levels are TTL and 2.5V to 5V CMOS compatible. The quiescent supply current is a very low, less than Applications 1A. Cellular Telephones The AAT4282B is available in a Pb-free, low profile 2.0 Digital Still Cameras 2.0mm TDFN22-8 package and is specified over the Hotswap Supplies -40C to 85C temperature range.
