AAT4282B Slew Rate Controlled Load Switch

The AAT4282B SmartSwitch™ is a member of Skyworks' Application Specific Power MOSFET™ (ASPM™) product family. The AAT4282B is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 67m, allowing increased load switch current handling capacity with a low forward voltage drop. The AAT4282B offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. A slew-rate selector pin can switch between fast and slow slew rate. The AAT4282B load switch operates from 1.5V up to 6.5V, making it ideal for both 3V and 5V systems. Input logic levels are TTL and 2.5V to 5V CMOS compatible. The quiescent supply current is a very low, less than 1μA. The AAT4282B is available in a Pb-free, low profile 2.0 × 2.0mm TDFN22-8 package and is specified over the -40°C to 85°C temperature range.
