AAT4280A

AAT4280A Slew Rate Controlled Load Switch General Description Features SmartSwitch™ The AAT4280A SmartSwitch is a member of 1.5V to 5.5V Input Voltage Range AnalogicTech's Application Specific Power MOS Very Low RDS(ON), Typically 80mΩ (5V) FET™ (ASPM™) product family. The AAT4280A is Slew Rate Limited Turn-On Time Options a P-channel MOSFET power switch designed for — 1ms high-side load switching applications. The device — 0.5µs has a typical RDS(ON) of 80mΩ, allowing increased — 100µs load switch power handling capacity. The device is Fast Shutdown Load Discharge Option available in three different versions with flexible Low Quiescent Current turn-on and turn-off characteristics — from very — 25nA (typ) fast to slew rate limited. The standard AAT4280A TTL/CMOS Input Logic Level (-1) version has a slew rate limited turn-on load Temperature Range: -40ºC to +85°C switch and is functionally compatible with the 4kV ESD Rating AAT4250 device, while offering superior RDS(ON) 8-Pin SC70JW Package characteristics. The AAT4280A (-2) version features fast load switch turn-on capabilities, typically less than 500ns turn-on and 3µs turn-off times. The AAT4280A (-3) variation offers a shutdown Applications load discharge circuit to rapidly turn off a load circuit when the switch is disabled. All AAT4280A Cellular Telephones load switch versions operate with an input voltage Digital Still Cameras ranging from 1.5V to 5.5V, making them ideal for Hot Swap Supplies b...
