BQ34Z100-G1: BQ34Z100-G1 golden image qustion

Part Number: BQ34Z100-G1


I have two questions related to creating a golden image after the gas gauge has been configured and been through the process to learn the battery and achieve an update status of 6.

Question 1: The documents I have found on the process to create the golden image say to change the update status from 6 to 2 as one of the steps to create the golden image.   Are there any steps that need to be taken after the golden image is programmed on a new device / system before the Impedance Tack is re enabled?  If there are no special steps required, why would it be necessary to set the update status to 2?

Question 2: If there a list of other parameters that should be reset when the cycle count is reset?  I assume anything that says lifetime or any lifetime data would need to be reset. 

Thanks,

Doug

  • Hi Doug,

    1) The status is changed from a 6 to a 2 so IT is not enabled during testing on the production line. By sending the IT_ENABLE command to the device (done at end of production prior to sealing the device), the status will then change to a 0x06.

    2) This is correct.

    Sincerely,
