The DRV8805EVM is an evaluation module for DRV8805, provides an integrated solution for driving unipolar stepper motors. It includes four low side drivers with overcurrent protection and provides built in diodes to clamp turn off transients generated by the motor windings. Indexer logic to control a unipolar stepper motor using a simple step/direction interface is also integrated. Three stepping modes are supported 2 phase (full step), 1-2 phase (half step), and 1-phase (wave drive). This evaluation module comes with an on board MSP430 microprocessor which has been pre programmed for standalone operation. The regulated voltage for the MSP430 is provided by TPS7A4001. This evaluation module operates on power supply voltages from 8.2V to 60V.
- 1.5A continuous current single channel output
