AAT4280A  
Slew Rate Controlled Load Switch  
SmartSwitch  
General Description  
Features  
The AAT4280A SmartSwitch is a member of  
AnalogicTech's Application Specific Power MOS-  
FET™ (ASPM™) product family. The AAT4280A is  
a P-channel MOSFET power switch designed for  
high-side load switching applications. The device  
has a typical RDS(ON) of 80m, allowing increased  
load switch power handling capacity. 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 AAT4280A  
(-1) version has a slew rate limited turn-on load  
switch and is functionally compatible with the  
AAT4250 device, while offering superior RDS(ON)  
characteristics. The AAT4280A (-2) version fea-  
tures fast load switch turn-on capabilities, typically  
less than 500ns turn-on and 3µs turn-off times.  
The AAT4280A (-3) variation offers a shutdown  
load discharge circuit to rapidly turn off a load cir-  
cuit when the switch is disabled. All AAT4280A  
load switch versions operate with an input voltage  
ranging from 1.5V to 5.5V, making them ideal for  
both 3V and 5V systems. Input logic levels are  
TTL and 2.5V to 5V CMOS compatible. The qui-  
escent supply current is very low, typically 25nA.
