The LED power driver section of automotive headlights utilizes high-performance, multi-channel BOOST and BUCK mode LED driver chips with SPI communication interfaces, compliant with automotive AEC-Q100 certification. These chips are suitable for adaptive high beam lighting (ADB), advanced front lighting (AFL), and laser lighting systems. The solution employs high brightness (HB) and smart LED technology to upgrade traditional automotive lighting solutions.

 Advantages of the N32G435 Chip:

• The solution uses a high-performance Arm® Cortex®-M4 core MCU, offering fast processing speeds and strong computational capabilities.

• Operating temperature range of -40°C to 105°C and 4kV ESD protection, ensuring high reliability.

• Communication with the BCM (Body Control Module) is achieved through a CAN interface. The BCM parses commands based on data collected from cameras or sensors, enabling the switching and adaptive control of functions such as high beam, low beam, fog lights, turn signals, and daytime running lights.

• The high-speed SPI interface supports up to 27Msps, enabling rapid transmission of LED control signals and refreshing LED displays.

• The 12-bit ADC features a maximum sampling rate of 5.14Msps, providing overcurrent and overvoltage protection for the product solution.
