Overview
EV-101 AAT4291 RGB EVAL Triple I/O Expander Load Switch with Serial Control Introduction This document discusses the AAT4291 RGB EVAL evaluation board and the application of the AAT4291 as an RGB LED driver.
Advanced RGB LED control is realized without having to use multiple discrete MOSFET switches controlled by multiple I/O pins from the system processor.
Only one digital I/O pin is needed for complete, independent brightness control of each of the R, G, and B LEDs.
The AAT4291 SmartSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family.
The AAT4291 has three P-channel MOSFETs configured for use as a microprocessor I/O expander.
Having independent d...
