MIKROE has released Stepper 28 Click, an add-on development board for controlling 2-phase bipolar stepper motors. The board ...

This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

Two-chip designs combining a microcontroller or DSP with a highly integrated driver IC simplify the design of a stepper-motor controller, while also enabling sophisticated control features that would ...

Allegro MicroSystems, Inc. announces a new programmable stepper motor driver IC with improved programmability and diagnostics. The A4979 is a flexible microstepping motor driver with built-in ...

The DSC4020 bipolar chopper drive is designed for development projects — just connect a single power supply and motor and the drive is ready to run. The DSC4020 bipolar chopper drive is designed for ...

Higher-than-normal operating voltages give steppers better torque at high speeds — but watch that current! • The inductance in a stepper-motor phase winding limits how fast current rises when power is ...
