Key Document


This TIDA-00146 reference design provides an integrated motor driver solution intended to drive a bipolar stepper motor in an automotive adaptive front light positioning application. This design features off battery capabilities with 45V maximum operating supply voltage. Along with, internal shutdown functions provided for overcurrent protection, short circuit protection, undervoltage lockout and overtemperature. This design incorporates the DRV8824EVM board to create the solution.

  •  Wide Vin (42V Load dump capable)
  •  1/32 Microstepping built in indexer (smooth quiet motion)
  •  DRV8824 On-chip protection enables higher system reliability
  •  VM sleep mode minimizes power consumption (battery drain)
  •  Step / Direction control interface (2x GPIO pins)
