Part Number: BQ76905
Other Parts Discussed in Thread: BQ77915

Tool/software:

Hi team,

Do we have balance devices can meet below request? Thanks.

  • Number of series cells: 4
  • Passive balance current: 100mA
  • No need for battery monitor (we can also recommend integrate monitor function devices if we haven't dedicated device only for balance)

Best Regards,

Ryker

    Hi Ryker,

    For 4s, the BQ76905 and the BQ77915 are the two best options.

    Note that they both can only reach 50mA of internal balancing current, so the customer would need to implement an external balancing circuit to reach 100mA.

    Regards,
