Melexis has launched the MLX81117, its latest multichannel RGB LED driver. This new device supports the MeLiBu high-speed communication licence-free IP, which facilitates intelligent animated automotive lighting concepts.
The technology is already being employed by leading global car manufacturers to improve the safety features of their latest Models. The device increases the MeLiBu product family with even better colour-mixing accuracy of delta UV of <0.01.
The device integrates the MeLiBu high-speed communication interface IP. MeLiBu controls individual LEDs to achieve the lighting effects determined by the vehicle’s systems. The intelligent RGB-LED controller also gives real-time compensation of any colour drift caused by environmental changes and colour-mixing accuracy with a delta UV of <0.01% to remove any distinguishable differences between LEDs.
The LED driver IC’s extra features include brightness control over a wide dimming range, which provides adjustments for natural light levels. The device complies with ISO 26262 functional safety requirements up to safety integrity level B (ASIL B), and the design also provides low EMI and high levels of immunity to assist designers in meeting EMC regulations.
“The MLX81117 is the second product offering from Melexis to integrate its MeLiBu technology, which enables a scalability approach of the lighting system as well as new application functions,” said Michael Bender, product line manager Embedded Lighting, Melexis. “It extends our support for advanced light functionality, and we are excited to see leading automotive manufacturers already include it in their new models to deliver a safer driving experience.”
