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

Description

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.
