Hi
My customer is using DRV8805.
He drives uniporor stepping motor by 2-Phase exection.
Is there dead time between OUT1_ON->OUT1_OFF and OUT3_OFF->OUT3_ON?
Best regards
Shimizu

Shimizu,
There must be dead-time between on-off trasnstions of OUT1 &3 and Out2 &4 for full step 2-phase excitation step. I could not find the figure in data-sheet, so I will contact the desginer and some-one motor application team will answer the query.

Hi Wilson
Thank you for your support.
Actually, My customer has issue.
This question was done to look for its cause.
Issue is "under shoot" at being to "ON" integrated FET.
Please see attached file.
I think that this event is not cause of FET ON.
When _X became simultaneously "ON" with X in uniporor motor, is there a possibility which becomes such event?
Best regards
Shimizu
