BQ27542-G1: Pack configuration LSB descriptions

Part Number: BQ27542-G1
Other Parts Discussed in Thread: BQSTUDIO

Hello Sir:

We refer the pack configuration descriptions of TRM, but we found that bit 1~3 of LSB were not the same with BqStudio.

Please refer below figure.

Would you please let us know should I follow the description of TRM?

Or does there has new functions of these three bits?

Looking forward your recommendations.

Thanks a lot.

    Hi,

    These three bits are named differently in the TRM than what is seen in BQStudio but their functionality is the same. SOCHOLDOVRCHG and SOCHOLDOVRDSG  simply hold the state of charge at 100 and 0 respectively while an overcharge or over discharge condition is present.

    Best Regards,

    Jackson
