DRV8302 Fault after Spark (solved)

Postby Trucki » 14 Dec 2016, 13:47

Hi there,

I sucessfully soldered me a VESC 4.12. It already worked fine.
Then I connected it to my 10s battery without an anti spark switch and without capacitors (I'm such an idiot!).
Of course the DRV8302 burned and the magic smoke escaped.

That's why I soldered a new drv8302 on my board. I don't think that I have any unwanted joints, but the vesc isn't working. I'm getting the drv8302 fault. The 5V Buck converter is working. GVDD and AVDD is always ~0V.

Can somebody help me?

Thanks

Trucki

Thanks Trucki
