How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These ...

Advanced internal current sensing provides better current regulation in bipolar stepper motor drivers, which improves the quality of motion.
