GENERAL DESCRIPTION
FEATURES
SmartSwitch™ 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 both 3V and 5V systems.
