BQ76942: Can balancing be enabled for all cells at once externally?

Part Number: BQ76942
Other Parts Discussed in Thread: BQ76952

Can you confirm on the BQ76942 that balancing can be manually enabled for all the cells at once from an external microcontroller? My client would like to use the balancing function to discharge the battery for storage. I have designed our test board with external balancing fets and resistors per the TI app note on the topic.

    hi Alex,
    I think your question may have been covered in the note below from the application report "Cell Balancing with BQ76952, BQ76942 Battery Monitors"

    Note on Adjacent Cell Balancing: Care should be taken when using host-controlled balancing to ensure the power dissipation is at safe levels. Adjacent cell balancing is not possible in autonomous mode, but can be done in host-controlled mode. Adjacent cell balancing should only be used is special cases after careful consideration. Care must be taken to not exceed the abs max 100 mA cell balancing current limit or the abs max VC0 input voltage limit
