Hi,

I am working on BMS project and using  BQ77915 IC in circuit.

I am unable to measure Quiescent current of IC.

Please tell me procedure for measuring exact  Quiescent current.

    Hi Vinod,

    The quiescent current of our IC is defined as Icc and Ihib in section 8.5 of the datasheet. In this table, you can see the test conditions for these values. We guarantee that Iq will be within the range specified in the datasheet for those test conditions. If you would still like to measure it yourself, you can measure the current of the VDD pin and subtract the currents from the CHG, DSG, and LPWR pins.

    If you want to learn some more about Iq, you can refer to this article:
