LIN-to-LIN Master-Slave-Gateway RGB-Ambient Light Controller - MLX81120

Product description

The MLX81120 is a fully integrated LIN Slave IC for ambient light applications.

Thanks to four high voltage capable outputs it is possible to drive independently one RGB LED and additionally one white LED if necessary. It is suitable for bus systems according to LIN 2.x as well as SAE J2602. The MLX81120 also has an additional UART and LIN physical layer that allows the MLX81120 to act as Master to a private LIN Bus. The combination of two LIN physical layers, LIN protocol controller, microcontroller, and easy to use IO configurations make it possible to develop in a short timeframe small BOM, low cost, but very powerful and flexible LIN Slave nodes.
