Along with respective step/direction and phase/enable control interfaces, DRV8880 and DRV8881 have 2.0 A FS capacity and feature AutoTune™ on-chip intelligence. Latter monitors motor performance under varied conditions over lifetime and adjusts decay settings appropriately. Featuring step/direction interface, DRV8885 (1.5 A FS) and DRV8884 (1 A FS) bipolar stepper motor drivers integrate current sensing to promote accurate regulation, and conserve board space, and simplify routing.
