MLX81116 Device Support by ProMik

Advanced LED Driver with MELibu® for Automotive Applications

With the MLX81116, Melexis introduces an intelligent multichannel LED driver with MELibu® communication, specifically developed for demanding automotive lighting applications. The device enables control of multiple RGB LEDs via a single differential line, meeting the high standards of modern ambient lighting in vehicle interiors. MELibu® (Melexis Light Bus) allows synchronous control and diagnostics of multiple devices – all with minimal wiring effort. Outstanding features such as the integrated LIN interface, high current regulation accuracy, and the ability to control complex lighting animations make the MLX81116 an ideal component for dynamic lighting solutions in automotive environments. The device supports 16-bit PWM resolution per color channel, on-chip memory for custom lighting sequences, and extensive diagnostic functions to ensure system reliability.

ProMik now offers complete support for integrating the MLX81116 into automotive electronics manufacturing. Programming the MLX81116 requires in-depth understanding of memory initialization, LIN address management, and the configuration of lighting sequences. ProMik provides not only high-performance flashing solutions but also implements highly customized test processes for parameter verification, communication testing, and production-specific adaptations – all integrated into a unified production setup.
