TIDA-00111, Stepper Motor System Reference Design with Medium Torque Drive

TIDA-00111, Stepper Motor System Reference Design implements an MSP430, 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 32V and max current is 2.5A. A multitude of configuration options allow fine tuning of the current waveform, including the regulated current level, the Micro-Stepping 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
