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 ...

The SLA7070MPRT series are unipolar two-phase stepper motor driver integrated circuits (ICs). This device uses a clock input method as a control signal input method, enabling full control of the ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

One constant trend in the automotive world is the push to reduce the size of electronic components and electronic control units (ECUs). While this development has many benefits for car manufacturers ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

In this EDN Magazine article, Phill Leyva and Bill Quach of Maxim Integrated Products describe a stepper motor-driver circuit based on Maxim's MAX 9715, a tiny, surface-mount, 2.8W Class D audio ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.
