Other Parts Discussed in Thread: DRV8849
Tool/software:
The DRV8845 is fully pin-to-pin compatible and software compatible with the Allegro A3988, A5988, A5989, and Relmon MS3988 and MS3989. This means that you can directly replace these parts with DRV8845 without making any footprint or software changes to your system.
You can evaluate and compare the devices both on the TI evaluation board, the DRV8845EVM.
The applications team has shown that these devices can be evaluated on our EVM:
In addition to all the features of the A3988, the TI DRV8845 has Smart Tune which improves system efficiency and thermal performance:
Here are some further advantages of DRV8845:
Furthermore, there is a similar device the DRV8849 that has an integrated indexer up to 1/256 microstepping. It also has integrated current sensing with IPROPI output, eliminating the need for bulky external sense resistors.
