With AnalogicTech's AAT4295 and AAT4297, designers can now support up to two RGB LEDs while eliminating the need for discrete MOSFETs and save the GPIO lines for other system functions.
To generate the three colours in an RGB LED, designers must typically sequence the diodes and control the current going to each separate red, blue, and green diode within the package They would typically need to use three separate MOSFETs, all the associated interface circuitry, and three GPIO pins on the system processor to drive the RGB LED
