Texas Instruments DRV8889-Q1
The DRV8889-Q1 and DRV8889A-Q1 are fully integrated stepper motor drivers, supporting up to 1.5 A full scale current with an internal microstepping indexer, smart tune decay technology, advanced stall detection algorithm, and integrated current sensing. The device supports up to 1/256 levels of microstepping to enable a smooth motion profile. With advanced stall detection algorithm, designers can detect if the motor stopped and take action as needed which can improve efficiency and reduce noise.| Part No. | DRV8889-Q1 |
