Stepper motor drivers – Featured products
Our portfolio of stepper motor drivers are suited for a wide range of industrial and automotive applications. Select the device best suited for your systems requirements based on key features, including smooth motion, small solution size and advanced diagnostics below or view the portfolio.
Smooth, silent, precise
Our newest stepper motor drivers features smart tuning and high microstepping functionality, enabling better and more precise current regulation, lower ripple efficiency and up to 10% lower audible noise. While traditional designs use a mix of fast, slow and mixed decay with lower microsteps, ours use smart tune ripple control, 1/256 microstep and tight current accuracy to minimize noise and maximize smoothness of motion.
To learn more about the smooth motion feature in stepper motor drivers, read the application reports How to Improve Motion Smoothness and Accuracy of Stepper Motors and How to Reduce Audible Noise in Stepper Motors.
Small solution size
Our new stepper motor drivers help reduce system size, complexity and BOM cost with innovative small packaging and integrated current sensing. Traditional designs use bulky shunt resistors and other components to accurately measure current, which uses a significant amount of board space. Integrated current sensing eliminates the need for that, reducing the board size, cost and routing efforts.

Protection & diagnostics
Without proper monitoring and control, damage, excessive current draw, stalling or overheating can occur in motor systems. Our standard and advanced protection features make sure that in the event that something goes wrong with the motor operation, the driver helps protect the system from harm.
Open loop systems like stepper motors lack the ability to detect end of line or mid way stall conditions causing over heating and audible noise. Our Stepper motor drivers with integrated stall detection can detect motor status while eliminating need of hall sensors. Other advanced protection features include offline fault detection, automated dead time control and stall and open
