This bipolar stepper motor system implements an MSP430, a DRV8818, and a NEMA 23 motor. It's suitable for applications requiring up to 140 oz-in of torque, and up to 800 RPM. Motor voltage support is 8V to 35V, and max current is 2.5A. A multitude of configuration options allow fine tuning of the current waveform, including the regulated current level, the microstepping applied, H-bridge FET states during current decay, the time interval of current decay, and current deglitch time. The motor drive stage has integrated protection from short-circuit, shoot-through, under-voltage, and over-temperature.

The DRV8818 evaluation module (EVM) demonstrates the capabilities and performance of the DRV8818 integrated micro-stepping motor driver from Texas Instruments. This EVM comes with an on-board MSP430 microprocessor which has been pre-programmed for standalone operation. The regulated voltage for the (...)
