Tool/software:

Dear Team
I am developing a servo gripper that drives multiple motors using DRV8316CR, and I am contacting you because of a problem.
I made the first board and tested it, and found that DRV8316CR is not working at all.
I checked and found that the nSLEEP terminal is open. This seems to be the problem.
So I want to connect nSLEEP(23), NC(24), AVDD(25) 3 terminals. Please let me know if 3.3V can be input to the NC terminal.
Thank you.

Hi,

I have looped in the correct contact. One question to clarify, are you referring to connect DRV8316 AVDD to nSLEEP? If so, that configuration will not work. nSLEEP need to be powered using external supply. Example configuration in https://www.ti.com/lit/ug/slvubz9b/slvubz9b.pdf

Regards,

Manu
