Part Number: DRV8332-HTHi Team,I'd like to use the DRV8332-HT for its guaranteed 1000hours over 165°C, the drawback I face now is that I should control it with 6PWMs or 3PWMs which is complicated; I...

Thank you very much Dear Sean :) your reply is fast ,and correct. Good luck!
View ArticleRE: shunt-resistor in each phase in( Directly measurement on the phase line ).
as you know FAST needs to have voltage feed back sensors as well as current ,since the ground of HV(1200v) is directly connected to vss Microcontroller ,it is not good I think, is there any way to to...

FAST needs the voltage feedback, so you will need to find some way to provide it. You could look into something like SDFM for isolated voltage sensing, which is a typical design choice Sean
