Multichannel RGB-LED driver brightens interior lighting in automotive applications
MELEXIS MLX81116, a multichannel RGB-LED driver supports the MeLiBu high speed communication IP to enable intelligent animated automotive lighting concepts. An increasing number of car manufacturers are looking to introduce animated lighting into the cabin, as a way of conveying important driver-assistance prompts and vehicle-status information. Key engineering challenges include maintaining consistent color across all the LEDs in the lightbar, and ensuring they all change together, at the same time. Device addresses this through its high-speed communication interface IP, MeLiBu, which controls all individual LEDs separately in the lightbar to produce the lighting effects commanded by the vehicle. The intelligent RGB-LED controller also provides real-time compensation of any LED color drift caused by environmental changes.
