Hello Rick,
Thanks for the help. We removed R7-R9 and it fixed a few things such as
- AVDD - now 6.6 V
- DVDD - now 3.3 V
Yes we are setting EN_GATE high and yes we see ~40mA current draw when we set EN_GATE HIGH
The problems we are currently having include
- FAULT is low (around 0.8V)
- Gate driver voltage for all 6 MOSFETS is at 0V
Things we're not sure about
- When we test across CP1/CP2 we get 170mV at ~500kHz
- Is the SS_TR cap absolutely necessary? We didn't attach one because the initial torque required to move the car is very large, therefore we wanted the output rise time to be as short as possible
- The DRV8302 get's hot when PVDD1/PVDD2 are connected to 20V+
