Code-free LED driver simplifies automotive LED design
As LED systems are increasingly used in automotive applications, Melexis develops a highly configurable, code-free LIN LED driver that simplifies the development of dynamic RGB-LED automotive ambient lighting applications. In addition to reducing development time, the MLX80124 also eliminates the need for embedded software development expertise, Melexis said.
“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, Melexis, in a statement. “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 smart LIN RGB ambient light controller features an intuitive graphical user interface that engineers use to access configurable parameters without writing or compiling code. It features high-voltage output drivers, each offering configurable current sources up to 60 mA to support RGB ambient lighting configurations. It is fully qualified to AEC-Q100 and compliant with ISO 26262 up to ASIL B for automotive-grade ambient lighting systems, providing full lighting functionality.
The LIN LED driver delivers precise, LED-agnostic RGB color mixing with temperature compensation. Engineers only need to input the correct optical data for their selected LED.
Other features include a suite of diagnostic features, including open/short detection and supply monitoring. The operating temperature range is -40°C to 125°C.
The MLX80124 LIN LED driver, developed using advanced bipolar-CMOS-DMOS technology, is housed in a compact SOIC-8 package and features pin-to-pin compatibility with other Melexis drivers such as the MLX81124 or MLX81123. It is available now.
