RE: DRV8305 / DRV 3201 at 150V application

Hello Rick

I am not sure I follow your question. The inverter bridge is powered by a 150V battery DC bus in application. However, I see that the maximum PVDD per DRV8305 datasheet is +45V DC. What I am considering is detailed in the attached PNG file.

All connections highlighted in yellow will have a voltage divider to divide down the 150V down to acceptable levels for the DRV8305. The VCC for the chip will be powered by a separate 28VDC. 

I hope this is clearer. 

Thanks

Girish
