BQ27426: Prevent RSOC Change when Temperature over DoDatEOC Delta T

Part Number: BQ27426

Hi expert,

Customer used BQ27426 and enabled SMOOTH. When they did a test at full charged and changing temperature over 5degC(DoDatEOC Delta T), they see RSOC changed. Does it meet chip behavior? I thought if SMOOTH enable, the RSOC would only change when start/stop of charge/discharge. Is there a way to prevent the behavior but not changing the DoDatEOC Delta T threshold?

By the way, we found OpConfigB Bit3 in GUI has "RelaxRCJumpOK" but not in the TRM. Could you please also clarify is the feature really in the BQ27426? Is it correct we disable it can prevent the issue?

Thanks,

Allan
