A4988 DMOS Microstepping Driver

Allegro MicroSystems A4988 DMOS Microstepping Driver features a built-in translator for easy operation and is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes. This driver has a fixed off-time current regulator that can operate in slow or mixed decay modes. Easy implementation is accomplished with the translator, and simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, complex interfaces, or high-frequency control lines to program, making this driver an ideal fit for applications where complex microprocessors are unavailable or overburdened. 

Motor Drivers

Allegro MicroSystems Motor Drivers offer robustness and safety, delivering superior performance in harsh, high voltage environments. These durable drivers enable motors to run more quietly, efficiently, and reliably. The embedded motion control algorithms simplify designs while improving motor performance and time-to-market. The Allegro MicroSystems Motor Driver portfolio includes brushless DC drivers, brush DC drivers, and stepper drivers for automotive, industrial, and consumer applications.

Stepper Motor Drivers

Allegro MicroSystems Stepper Motor Drivers deliver quiet, efficient, smooth motion to minimize noise and vibration in stepper motor designs. The QuietStep™ adaptive stepper motor drivers utilize proprietary algorithms to reduce torque ripple and current distortion. To minimize ripple current for various operating conditions, these adaptive devices perform on-the-fly adjustments to the amount of fast decay during a pulse-width modulation (PWM) cycle. This adaptive feature boosts system performance, increases step accuracy, and lowers audible motor noise and vibration. Allegro MicroSystems Stepper Motor Drivers are available in a variety of options for automotive, industrial, and office automation applications.
