Stepper-motor driver reference design for adaptive front lights and dynamic headlight leveling

TIDA-020026

Design files

Overview

This reference design details a solution to drive and control two stepper motors for dynamic headlight leveling and swiveling in automotive headlight applications such as an adaptive LED driving module or a high-resolution DLP module. It uses a local interconnect network (LIN) system basic chip with integrated linear voltage regulator, two stepper motor drivers with a serial peripheral interface (SPI) and a microcontroller LaunchPad™ development kit.

Features
  • Up to 1-A motor current
  • CISPR25 compliant
  • Fully integrated solution

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
