AAT4282A - Dual Slew Rate Controlled Load Switch

General 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.

Key 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 compati.

AAT4282A Dual Slew Rate Controlled Load Switch General 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 slewrate 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.
