描述 Description

The AAT4282A SmartSwitch? is a member of AnalogicTech’s Application Specific Power MOSFET? (ASPM?) product family. The AAT4282A is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 60mΩ, allowing increased load switch current handling capacity with a low forward voltage drop. The device is available in three different versions with flexible turn-on and turn-off characteristics – from very fast to slew-rate limited. The standard 4282A (-1) version has a slew-rate limited turn-on load switch. The AAT4282A (-2) version features fast turn-on capability, typically less than 500ns turn-on and 3μs turn-off times. The AAT4282A (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. An additional feature is a slew-rate selector pin which can switch between fast and slow slew rate.
All the AAT4282A load switch versions are designed to operate from 1.5V up to 6.5V, making them 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 1μA.
The AAT4282A is available in the Pb-free, low profile 2.0x2.0mm FTDFN22-8 package and the SC70JW-8 package and is specified over the -40°C to 85°C temperature range.
