INA237: The violation at VCM negative voltage when the low side detect

Part Number: INA237

Hi team,

My customer measured the waveform when the power in is pluging-in.

They found the IN+ and IN- are over -0.3V. They probes the sense resistor and IC ground. Please find the waveform.

Do you have any concern about negative voltage? Our datasheet mentioned -0.3V negative for VCM.

If this is out of our spec, could you help to suggest a work around circuit. I can sent you the SCH offline.

Do we have the higher voltage limitation while in short pulse voltage/current for INA237? 

Or what is the acceptable voltage spike range with low energy pulse?

Thanks,

Leo
