High-voltage microstepping motor driver IC with built-in translator and overcurrent protection

High-voltage microstepping motor driver IC with built-in translator and overcurrent protection
The new A3987 from Allegro MicroSystems Europe is a microstepping motor driver IC which combines an output drive capability of 50 V and ±1.5 A with built-in translator circuitry and overcurrent protection. The new device is designed to operate bipolar stepper motors in full, half, quarter and sixteenth step modes, and includes a fixed off-time current regulator which has the ability to operate in slow or mixed decay modes. Typical applications are in office equipment, medical and scientific instrumentation and industrial systems.
