BQ27Z746: The self-consumed current in sleep mode keeps fluctuating

Putong daz
Prodigy 150 points
Part Number: BQ27Z746

Tool/software:

In sleep mode, the measured self-consumption is approximately 22uA, but it will adjust to 81uA every few seconds and keep fluctuating in this cycle. Is this normal? Can the extended time for the peak self-consumption of 81uA be set? Please refer to the attached document video for the data

    Hello, 

    This is normal. When measuring the gauge iq, it is important to take the averaged iq over at least a 30 second period. If you do this you will find iq numbers similar to what is spec'd in the datasheet. 

    Regards,
