Technology Platform for Modern Automotive Lighting Solution Development
The lighting systems in modern automobiles are largely controlled by the body electronics. We have developed a Body Control Module reference design capable of catering to the demands of new-age automotive lighting systems.
Our Body Control Module reference design is based on RH480 microcontroller- an automotive-grade MCU. Equipped with High-side and low-side drivers, the BCM can be used to control external lamp loads (headlamps, indicators) as well as the internal lighting systems (cabin lighting).
The highlight of the BCM reference design is also the LED drivers capable of controlling both external and interior lighting (cabin lighting) solutions.
These state-of-the-art features make our BCM reference design a complete package for managing the automotive lighting systems.
Modern lighting requirements of automobiles have evolved. Passengers as well as commercial vehicles require automotive lighting systems that are highly efficient, dynamic and exhibit highest level of safety and comfort.
From adaptive headlamps to smart lighting systems, modern automotive lighting solution make use of LED drivers, sensors and high side/low-side drivers to deliver state-of-the-art interior and exterior car lighting. Advanced diagnostics powered by DoIP and UDS adds another dimension of safety in the new-age automotive lighting systems.
