BQ25882: BQ25882 ADC conversion in battery only mode

Part Number: BQ25882
Other Parts Discussed in Thread: BQ25883,

Hi Team,

Our customer is changing BQ25883 design to BQ25882 due to shortage issue, they need BQ25882 to report NTC status in battery only mode.

however, there is a statement  in BQ25882 but not in BQ25883. customer has concern with BQ25882 cannot report NTC status in battery only mode.

I think below statement  is suggest customer to save power but need team double confirm here. 

Btw, customer would like to know BQ25883 quiescent current with ADC enable (our datasheet only show 12uA w/ADC disabled).

Do we have ideal about BQ25883 quiescent current with ADC enable?

Thanks & Regards

Eddie

    Hello Eddie,

    Even though that statement is not in the BQ25882 datasheet, the TS_ADC functionality is the same as on BQ25883.

    Because we do not have quiescent current with no Vin and with ADC enabled listed in the EC table, we cannot warranty a value for that quiescent current.

    Regards,
