The MLX81112 LIN RGB slave provides a single chip IC solution for driving up to four LEDs (RGB+1) via constant current sources in automotive ambient lighting applications. Every output can be programmed to a maximum current of 48 mA through the built-in Flash memory.

All necessary components like physical layer LIN transceiver, LIN controller, voltage regulator and 16-bit RISC-based microcontroller, as well as supporting functions like ADC, 16-bit current modulation, constant current high voltage capable outputs and LED color temperature compensation are integrated into the chip.

It also includes the possibility for LIN auto-configuration and can thus be used for other applications requiring a low pin count fully integrated LIN slave. The LIN protocol handler meets all LIN standards including LIN2.x, as well as SAE J2602.

To support a high thermal performance by keeping the low cost target, our MLX81112 is offered in a thermally enhanced SOIC8 package.
