Stepper Motor Drivers

Deliver Quiet, Efficient, Smooth Motion

Minimize noise and vibration in your stepper motor designs with our QuietStepTM adaptive stepper motor drivers. We offer a complete lineup of stepper motor drivers for office automation, industrial, and automotive applications. Our advanced QuietStepTM solutions use proprietary algorithms to reduce torque ripple and current distortion. To minimize ripple current for the various operating conditions, QuietStepTM adaptive stepper motor drivers perform on-the-fly adjustments to the amount of fast decay during a pulse-width modulation (PWM) cycle. This adaptive feature improves system performance, reduces audible motor noise and vibration, and increases step accuracy.
