Multi-channel LIN RGB controller with 24 drivers - MLX81118

Product description

The MLX81118 is an automotive LIN RGB controller with 24 LED drivers suitable for ambient lighting applications.

Its LIN interface is compliant with LIN2.x and SAE J2602 standards as well as ISO 18987 and supports auto-addressing.

The MLX81118 complements the MLX81115 and MLX81113 to address various applications where multiple RGB LEDs need to be controlled via one LIN node within one or several modules, for example, in door trim parts or dashboard applications. The multi-channel support means that the MLX81118 is also suitable for light animations controlled via LIN.

The MLX81118 has been developed according to ISO 26262 and supports safety related system implementations up to ASIL-B.

To accelerate application development, a complete toolchain including evaluation board, In-circuit-emulator, and C-Compiler package is available on request. Essential software including a LIN driver, color mixing, math library, and IC initialization routines are also available. Do not hesitate to get in touch with your sales representative.

For custom SW support for the application you can refer to Melexis recommended third parties.
