Texas Instruments DRV8849EVM Stepper Motor Driver Evaluation Module (EVM) is designed to help evaluate the DRV8849. The DRV8849 is a dual-stepper motor driver for industrial and consumer applications. The device is fully integrated with four N-channel power MOSFET H-bridge drivers, one micro-stepping indexer for each stepper, and integrated current sensing. The DRV8849 can drive up to 1.5A (limited by board design). The DRV8849 uses STEP/DIR interface to control the direction and step rate of the stepper motor. The Texas Instruments DRV8849 protection features are provided for supply undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature.
