AAT4291 Datasheet | AAT

AAT4290/91 I/O Expander Load Switches with Serial Control General Description The AAT4290 and AAT4291 SmartSwitch products are members of AnalogicTech’s 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 mon 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 AnalogicTech’s Simple Serial Control™...
