Part Number:DRV8702D-Q1
Hi,
I have a DRV8702D-Q1 on a board. I've configured it very closely to the DRV8702D-Q1EVM.
However on my hardware I have the nSleep Pin connected to DVDD, my assumption here was the voltage regulators would be powered, the nSleep pin pulled high and life would be happy.
In my situation I have no AVDD or DVDD voltages, I assume this is because the nSleep pin is low. Referring to the DRV8702D-Q1.PDF, table 8.3.1.1 it seems that at any time nSleep is low, the regulators are disabled, however if I refer to 8.2 Functional block diagram, it suggests that the regulators are independent of the nSleep function as the control logic is powered from DVDD.
My question is what happens if I pull nSleep high from another voltage source (such as a IO pin on a MCU)?. Are there any dangers in risking powering the DRV8702D-Q1 via parasitic power through the nSleep pin?
Thanks
Stomp!.
