All,
We found problem on UCD7231, CSN and CSN of UCD7231 short to GND. just would like to check with TI, without the RSH_Sense could affect VGG, CSP, CSN short to GND or not. now we do not a resistor from HS sense pin to the drain of high side mosfet and found this kind of issue.
Best Reagrds,
Naret
