AAT4291AIJS1T1 Skyworks Solutions, Inc.
Power MOSFET Transistor
MFG Part Number: AAT4291AIJS-1-T1
The AAT4290 and AAT4291 SmartSwitch products are members of Skyworks' Application Specific Power MOSFET (ASPM™) product family. The AAT4290 and AAT4291 are five and three P-channel MOSFETs, respectively, config­ured for use as a microprocessor I/O expander. Having independent drain outputs and a common source input, they operate with an input voltage ranging from 1.8V to 5.5V, making them ideal for 2.5V, 3.3V, or 5V systems, as well as systems powered by lithium-ion/polymer batter­ies. Each switch features a 500ns turn-on time. The switch states are controlled by Skyworks' Simple Serial Control (S2Cwire™) interface which permits ease of con­trol and efficiency of size. The quiescent supply current is very low, typically 4.5?A. In shutdown mode, the supply current is reduced to less than 1?A.
