Anti-theft Enabled MLX81114 RGB LED Controller with Memory Access Protection for Automotive Ambient lighting

MLX81114 LIN RGB Controller

Melexis has introduced the MLX81114, a new addition to the IC family for supporting the future growth of RGB LED-based automotive ambient lighting, also known as LIN RGB. As an advanced variant of the MLX81113, the MLX81114 LIN RGB controller comes with a memory access protection for enabling anti-theft applications in SOIC packaging.


The MLX81114 has been designed with on-chip memory, high output current, and EMC robustness next to the ISO 26262 functional-safety compliance to support its use in ASIL-A classified systems. The new device combines a physical layer LIN transceiver and a LIN protocol controller with current-controlled outputs. This makes it possible to develop in a short timeframe simple, but powerful and cost-efficient ambient light modules connected to LIN bus systems.


The MLX8114 can deliver automotive lightings with personalization and differentiation within the driver’s cabin for vehicles from entry-level to mid-range and luxury models.
