描述 Description

The AAT4282B SmartSwitch™ is a member of Skyworks'Application Specific Power MOSFET™ (ASPM™) productfamily. The AAT4282B is a dual P-channel MOSFET powerswitch designed for high-side load-switching applications.Each MOSFET has a typical RDS(ON) of 67mΩ, allowingincreased load switch current handling capacity with a lowforward voltage drop. The AAT4282B offers a shutdownload discharge circuit to rapidly turn off a load circuitwhen the switch is disabled. A slew-rate selector pin canswitch between fast and slow slew rate.
The AAT4282B load switch operates from 1.5V up to6.5V, making it ideal for both 3V and 5V systems. Inputlogic levels are TTL and 2.5V to 5V CMOS compatible.The quiescent supply current is a very low, less than1μA.
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.
