BQ76930: OV/UV hardware protection

Hope Chen
Expert 1030 points
Part Number: BQ76930

Dear Sir，

I  use the BQ76930 to Manage the 10S  cell  . When the balance condition is reached, I turn on the balance of BQ76930. The voltage sampled by BQ76930 will fluctuate greatly and sometimes trigger OV/UV

hardware protection.

Can you help check the issue and give us advice tell me 

Thanks a lot

    Hi Hope,

    This might be caused by slow settling on the input filters. Check the values of Rc and Cc on the cell inputs to see if they are at the high end of the recommended range. Reducing these values may help resolve the issue.

    Best regards,

    Matt
