BQ34Z100: Positive current when no load

Hi,

My customer is using the BQ34z100 in one of his projects and so far is going well. However, when there is no load connected, it is showing a positive current into the battery even when there is no charger connected to the system. Around 30mA with 4:1 scaling (120mA charge).

Have you seen this positive current readings before, and do you know what may be causing it? Maybe SNR issues?

And do you have any suggestions on how to alleviate or how to offset/ignore that value?

Thank you,

Josh
