Stepper Motor Drivers

Deliver Quiet, Efficient, Smooth Motion

Minimize noise and vibration in your stepper motor designs with our QuietStep^TM adaptive stepper motor drivers. We offer a complete lineup of stepper motor drivers for office automation, industrial, and automotive applications. Our advanced QuietStep^TM solutions use proprietary algorithms to reduce torque ripple and current distortion. To minimize ripple current for the various operating conditions, QuietStep^TM 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.
