Single Channel LIN RGB Slave Ambient Light Controller - MLX81113

Product description

The MLX81113 IC is a fully integrated low-end LIN slave for ambient light applications in automotive environments to drive via LIN bus RGB LEDs.

It is suitable for bus systems according to LIN 2.x as well as SAE J2602. The combination of a physical layer LIN transceiver and a LIN protocol controller together with current-controlled outputs make it possible to develop in a short time frame simple, but powerful and cost-efficient ambient light modules connected to LIN bus systems.

For more information and documentation, please don’t hesitate to get in touch with your sales representative.
