您好, If the BQ76952 reports inaccurate values after calibration (assuming calibration was done correctly), then it is likely that one of the VREFs has changed in value significantly relative to the other (This is very odd, we've never seen this before.). To check this, a read on DASTATUS5() can be done.
If the VREF bit is set in the Settings:Permanent Failure:Enabled PF C, this will trigger a PF if the reported value from the first two bytes of DASTATUS5() is below 26223 or above 32051 for four seconds
