This advancement streamlines vehicle interior and exterior lighting systems, lowering costs and complexity for manufacturers.
Melexis has introduced the MLX81119, a LIN-based 18-channel RGB LED controller with an on-chip DC/DC converter, designed to streamline automotive ambient lighting modules. By embedding power conversion directly into the controller, the Belgian semiconductor firm eliminates the need for an external DC/DC stage, significantly cutting component count, board space, and system cost. The integration also reduces thermal dissipation—a critical advantage in compact, enclosed lighting assemblies—without compromising LED drive precision or color consistency across all 18 channels.
The device communicates over a LIN bus, a lightweight, single-wire protocol already widespread in vehicle body electronics, allowing seamless connection to existing networks and simplified wiring harnesses. With 18 independent channels, it can drive multiple RGB LEDs for dynamic interior lighting effects (e.g., door panels, dashboard accents, and reading lights) while maintaining tight control over color and brightness. The on-board DC/DC converter adapts varying battery voltages to the LEDs' requirements, improving efficiency and thermal performance.
For automotive Tier-1s and OEMs, the MLX81119 reduces design complexity and validation effort. The lower component count shrinks module dimensions, freeing up valuable interior space and enabling sleeker lighting designs. Melexis positions the chip as a ready answer to the industry's push for more sophisticated, flicker-free LED ambient lighting that meets strict thermal and cost constraints.
