When I go to the dataflash screen, I get a message that the device is sealed. How can I unseal it so i can read values?

Thank you,

Hi Manuel,

The pack manufacturer will have sealed the device so they will have the appropriate keys.

Best regards

Hi Garry,

Thanks for the response. Actually we are the pack manufacturer. I don't really see a cook book procedure outlined in the datasheets that shows how to unseal the pack like in the newer bq gauges. Does one need to short certain pins on the IC? Is it just a software procedure?

I am looking for the procedure on unsealing it. Thanks.

Best Regards,

Manuel Covarrubias
