BQ76930 external cell balancing

Other Parts Discussed in Thread: BQ76930

Hi, 

I've designed a protection and balancing circuit with the BQ76930 and an external balancing circuit. Does it require any algorithm to be implemented or it will  work automatically after the configuration of cell balance registers.

    The bq76930 will automatically handle measurement and application of the balancing which is set in its registers, but will not implement an overall balance algorithm.  Your MCU needs to implement the overall balance algorithm and must decide which cells to balance when and set the appropriate register bits in the bq76930 to accomplish that desired balancing.
