Overview
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 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 AnalogicTech’s Simple Serial Control™ (S2Cwire™)...
