SMART MULTI-CHANNEL (RGB)-LED DRIVER
ENABLES HIGH-SPEED LIGHT ANIMATIONS
The MLX81116 is a fully integrated smart automotive LED driver with high-speed robust communication
(MeLiBuTM) between multiple LED drivers to enable applications with high LED counts for highly animated
light applications. All necessary components needed for LED driving as well as communication are
integrated and allow to develop powerful and cost-optimized animated light systems. For applications
requiring RGB-LEDs, the embedded intelligence allows a very high accuracy of the needed color mixing.
ASIL-B grade applications are supported as well thanks to the MeLiBuTM communication system. KEY FEATURES
