CCS/BQ27510-G3: BQ27510-G3

Part Number: BQ27510-G3

Tool/software: Code Composer Studio

Deandband was set to 68 in our application to resolve a ghost problem. We use Bq27510-G3 in our application. There is 0.2mA leakage current in our board.  What minimum current can be measured by BQ? 0.01mA, 0.1mA or 1mA? If minimum current that can be measured by BQ is 1mA, does it mean that current lower than 1mA is seen by BQ as 0mA? Can 0.2mA be seen by BQ?

If deadband is set to 34 or 17, what is minimum current that can be measured by BQ seperately?

    Hi

    I confirmed with our firmware engineer that a cc deadband of 17 filters a current of 1mA. 34 doubles that number so 2mA. Current lower than 1mA with a ccdeadband of 17 will be discarded. I am verifying if that is indeed the case.

    thanks
