Melexis Rewrites the Rules of Automotive LED Design with a Code-Free LIN LED Driver

­Melexis unveils the MLX80124, a highly configurable, code-free LIN LED driver. With its pre-defined, proven functionality and an intuitive graphical user interface, it is designed to radically simplify the development of dynamic RGB-LED automotive ambient lighting applications for engineers of all backgrounds.  

In automotive design, where ambient LED lighting is increasingly central, minimizing complexity and accelerating development is essential – especially as a greater number of LED systems are integrated. Recognizing this, Melexis has launched a code-free MLX80124 variant that simplifies the development process while delivering the full lighting functionality expected by tier 1 suppliers and OEMs.

The MLX80124’s unique innovation enables engineers to configure behavior without writing or compiling a single line of code. Instead, a GUI provides access to configurable parameters. The result is a streamlined, efficient workflow that reduces development time and removes the need for embedded software development expertise.

As a smart LIN RGB ambient light controller, the MLX80124 features high-voltage output drivers, each offering freely configurable current sources up to 60 mA – supporting RGB ambient lighting configurations. Developed using advanced BCD (Bipolar-CMOS-DMOS) technology, it is housed in a compact SOIC-8 package and features pin-to-pin compatibility with other Melexis drivers such as the MLX81124 or MLX81123. The device integrates a full suite of diagnostic features, including open/short detection and supply monitoring. It delivers precise, LED-agnostic RGB color mixing with temperature compensation – engineers simply input the correct optical data for their chosen LED.

With a working temperature range from -40 °C to +125 °C, fully qualified to AEC-Q100, and compliant with ISO 26262 up to ASIL B, the MLX80124 ensures robust performance for automotive-grade ambient lighting systems, all without requiring software development.

“This is a new level of product for Melexis. With its built-in functionality and full configurability, this IC offers engineers a radically simpler way to create automotive ambient lighting systems—without writing any code,” said [Michael Bender, Product Line Director] at Melexis. “As the world’s first code-free LIN RGB LED driver, the MLX80124 represents a major shift in how automotive lighting electronics are developed. It dramatically shortens design cycles while maintaining all the robustness and functionality expected by OEMs and tier 1s.”

The MLX80124 is available now, marking a pivotal step in Melexis's "code-free" strategy, a family of products aimed at simplifying design and freeing engineering resources for greater innovation. To discover more or to request samples, please go here.
