BQ28Z610 Learning Cycle Information Conflict

B-A

Other Parts Discussed in Thread: BQ28Z610

Hello,

My question is simply whether a learning cycle is necessary before the BQ28Z610 should be deployed? The technical reference manual mentions learning cycle use during production as it relates to certain parameters such as Fast_QMax_LRN for example. There is also the SLUA777 report detailing how to complete a learning cycle for the bq28z610 gas gauge. However, in the datasheet of the bq28Z610 IC, it specifically states that a learning cycle is not necessary and references the SLUA364B report which discusses the theory of the IT algorithm. It looks like possibly two against one in favor of a learning cycle, but could someone elucidate why there is this discrepancy?

Thank you for your time.

Blake

    Hi Blake,
    Sometime you might get off without carrying out a learning cycle, but to ensure accuracy, it is recommended to do so. pls carrry out learning and extract a golden srec which will be used to program multiple devices.
    thanks
