BQ76940: BQ76940 cell balance

Part Number: BQ76940

Hi,

I have a question for BQ76940. When BQ76940 is used for external balancing, can cell 5 and cell 6, cell 10 and cell 11 be balanced at the same time?

Thanks & best regards,

Lenna

    Hi Lenna,
    Yes. When all cells are used or the numbering from the bq76940 pins is retained, cells 5 and 6 are in different cell groups and can be balanced at the same time. Also for cells 10 and 11. The adjacent cell balancing limit is within the same group where the input resistors are shared and the pins have specific limits to the group reference.
