Part Number:DRV8323R
Hi
I have designed a BLDC driver with DRV8323RS.
VM and VDRAIN are saperated for different power sources and ground is weakly shorted on the PCB.
This is a situation.
I only put the power into VM (VDRAIN is open) and make ENABLE pin hgh.
And then I can check some voltage between VDRAIN and GND nearly close to VM
It seems that capacitors connected to VDRAIN is charged through VM.
Is it correct operation??
If I want to use the power sources can be tured on/off independently between VM and VDRAIN, what need I care about?
Brest regards
