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 of 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
