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.

EV-101 Features

* a fast 500ns turn- SmartSwitch™ on time. The switch states are controlled by the Simple Serial Control™ (S2Cwire™) serial digital interface. The quiescent supply current is very low, typically 5µA. In shutdown mode, the supply current is reduced to less than 1µA. Using RGB LEDs to generate various
