This design is an application of Texas Instruments’ DRV8880 stepper motor driver, an integrated motor driver solution for bipolar stepper motors. The device integrates two N-channel power MOSFET H-bridges, current regulation circuitry, and a microstepping indexer. The circuit design showcases how quickly Auto-Tune can adapt to changes in system inputs or motor characteristics without the need to apply any type of parameter tuning. Read more
