Car Ambient Lighting Solutions

The ambient automotive lighting Solution is designed based on the BAT32A237 chip of Arm Cortex ® M0+ core. LIN bus is used to communicate with the host, supporting sleep and wake-up, reducing the power consumption of the system.Through the pull-up and constant current switch control, combined with the current sampling circuit, the LIN auto-addressing function is implementation.

Performance characteristics

Automotive ambient lighting Solution:
◈ The main chip of BAT32A237 Conforms to AEC-Q100 Grade1 standard
◈ The function of auto-addressing is realized by sampling circuit and software, and the structure is simple
◈ RGB three-color lights are directly controlled by high-precision PWM
◈ Ambient mode is available, precise color and brightness adjustment
◈ it can automatically assign the address according to the node location
◈ Simplify storage and installation process, improve the Universality
