Power MOSFET Transistor
  
The AAT4280 SmartSwitch is a P-channel MOSFET power switch designed for high-side load switching applica­tions. The P-channel MOSFET device has a typical RDS(ON) of 80mW, allowing increased load switch power handling capacity. This device is available in three different ver­sions with flexible turn on and off characteristics from very fast to slew rate limited. The standard AAT4280 (-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 AAT4280 (-2) version features fast load switch turn on capabili­ties, typically less than 500ns turn on and 3?s turn off times. The AAT4280 (-3) variation offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. All AAT4280 load switch ver­sions operate with an input voltage ranging from 1.8V to 5.5V, making them ideal for both 3V and 5V systems. The AAT4280 also features an under-voltage lockout which turns the switch off when an input under-voltage condition exists. Input logic levels are TTL and 2.5V to 5V CMOS compatible. The quiescent supply current is very low, typically 2.5?A. In shutdown mode, the supply current decreases to less than 1?A.
