Application Note

How to Reduce Power Consumption in Stepper Motor Drivers Using Holding Torque

Abstract

This application note describes methods to reduce power consumption and improve system thermal performance using Texas Instruments' stepper motor drivers. This process is achieved by reducing the current consumption of a stepper motor during the holding mode. A manual method is proposed using the VREF reduction technique with DRV8818 as an example. This is followed by an explanation of the Standstill Power Saving Mode in advanced stepper motor drivers like the DRV8452 and DRV8462.
