    Hi Went,

    The ALERT pin is used to communicate to the BQ78350-R1 device that a coulomb counter measurement is available or that a fault has been detected by the AFE. If this pin is not connected correctly (tied to GND, high voltage, or floating), then the BQ78350-R1 will not be harmed. But it will not be able to gauge the battery correctly because it is no longer receiving current measurements from the AFE. It will also not be able to clear faults on the AFE.

    Best regards,

    Matt
