GENERAL DESCRIPTION
Highest integration, high energy efficiency, and a small form factor enable miniaturized, scalable, and cost-effective motor drive solutions perfectly suited for Nema 17, Nema 23, and even Nema 24 steppers. StealthChop+ ensures noiseless operation and maximum efficiency, optimal motor torque control, and dampening of mid-range motor resonances for a smoothly running motor with low mechanical vibrations. Combined with StallGuard+, CoolStep+, and µDcStep, this results in a highly efficient and versatile stepper motor driver. An unloaded Nema 17 motor automatically runs with as low as a few 10mA of supply current. ICS eliminates bulky external sense resistors, resulting in space and power savings. The integrated power MOSFETs' low impedance of ~40mΩ ensures high efficiency and low heat generation. Abundant diagnostics include an on-chip scope interface for tuning and checking (RT-OCSI), temperature and voltage ADC, and a full set of protection functions like short protection and thermal shutdown.
