DRV8873: nSLEEP

Tool/software:

Hi,

I evaluated circuit①. However, since the charge pump circuit inside the IC is disabled during sleep mode, even if I want to release sleep mode, there is no output from the DVDD and the IC does not operate.

Therefore, I am considering circuit②. I have a question.

1. Can I use another external power source as the pull-up power source for the nSLEEP pin?

2. Can I apply voltage to the nSLEEP pin when VM is not applied to the IC (power off)?

Best Regards,

Nishie
