General Description

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.

Integrated current sensing eliminates the need for two external resistors, saving board space and cost.
