RE: DRV8305: timing to detect over current protection

Hi Yamamoto-san,

Question 1:

Figure 13 on page 27 of the DRV8305 datasheet shows the following:

So, to answer your question, the longest possible interrupt time would be tblank + tdeglitch.  Here, tdeglitch = tVDS.  These should be labeled as the same thing.

Question 2:

In the example you gave, assuming tblank has already ended, the time between the over current event and our device signaling a fault would be tVDS
