Automotive Lighting & Smart Cockpit
Control and drive for dynamic ambient lighting, smart surfaces, interior and exterior lamps and reading lights, with color calibration, temperature compensation and vehicle-wide light-effect synchronization.
Automotive Lighting & Smart Cockpit
Automotive ambient lighting has moved from single-colour illumination to dynamic effects and smart surfaces. By integrating an MCU, a LIN transceiver and three 60 mA RGB drivers into one chip, RJL9123x solves three engineering problems: LED bin-to-bin colour variation, temperature drift, and loss of synchronization between lighting nodes.
Systems and scenarios covered
Typical scenarios
- Smart cockpit domain controllers powered from the primary supply
- dynamic ambient lighting and smart surfaces
- interior and exterior lamps, reading lights
- charging port ambient lighting
