Hi there,
I'm still playing around DRV8305 and find that GHx is PVDD and the source voltage of the high side is also PVDD when the input for INHx and INLx are both at 1/1 or 0/0.
The low side GLx voltage seems OK as it sits at 0.
The driver gets good gate drive voltage (PVDD+10v for high side and 10v for the low side) when INHx and INLx are in the different value.
The driver is in the default mode and the SPI register show DRV8305 is in the 6-PWM input mode.
So I wonder what would run wrong in this case?
Thank you!
