DRV8880 AutoTune operation

Other Parts Discussed in Thread: DRV8846, DRV8880

I'd like to understand details about AutoTune operation of DRB8880.
Is it same operation with adaptive decay on DRV8846 Figure 10, 11 and 12?

Hi Hide,

Yes. That is the basic scheme of the AutoTune. Also DRV8880 can be treated as a higher level adaptive decay with more parameters adaptively changing to achieve a smooth and accurate current regulation.
