Spin your stepper automatically


Sometimes you just want to make your stepper motor spin without the hassle of configuring the driver. Open-loop motor control was supposed to be easy … right? Cue the endless complaints about decay-mode optimization and ideal stepper motor performance.

TI designed its new smart tune technology to simplify stepper motor tuning and eliminate the iterative process most of us have experienced. Smart tune can adapt to changes in system inputs or motor characteristics without you having to tune your motor again. No, this technology will not help your music career, but hopefully, it will prevent your stepper motor from “singing.”

Watch this video for a quick introduction to smart tune technology and how it can help you save weeks to months of design time. You’ll find this technology on the DRV8846 and DRV8880.
