Smart multi-channel RGB-LED controller with 21 drivers - MLX81143
Product description
The MLX81143 is a fully integrated smart automotive LED driver with high-speed robust communication (MeLiBu®) between multiple LED drivers to enable applications with high RGB-LED counts for highly dynamic light animations within cars.
All necessary components needed for LED driving as well as communication are integrated and allow to develop powerful and cost-optimized animated light systems. The embedded intelligence allows a very high accuracy of the RGB color mixing as well as the support of ASIL B grade applications thanks to the MeLiBu® communication system. The MLX81143 extends the MeLiBu product family with a higher number of integrated LED drivers.
Key applications
- Highly animated light modules
- Interior driver communication by light
- Voice command signal confirmation
- Safety warning applications
- Advanced navigation support
- Blindspot warning
- Animated Rear Light and DRL
Evaluation kit and Software are available on request. Please contact Melexis for additional information.
