BQ76952: About the power consumption of single cell of bq76952

Part Number: BQ76952

Tool/software:

Hi TI experts,
I want to know the power consumption of single-cell voltage acquisition of bq76952. I didn't find this part in the specification. Do you have relevant test data?
I connected two sections on the schematic, for example, VC12 connected to VC13, and the power consumption of the section doubled, but there is no relevant description in the specification. Can you explain it? Thank you.

  • Hello,

    A couple of questions:

    1. How are you measuring the power consumption?

    2. Can you send your schematic and your .gg settings file?

    Best regards,

    Thomas Rainey

  • Hi Thomas,
    1. As shown in the attached figure, I connected the ammeter in series to the single-cell sampling line to measure the power consumption.
    2. Sorry, this cannot be provided for some reason.
    13S schematic design, I configured Vcell Mode to 0xabff, then VC15 and VC14 were connected, VC13 and VC12 were connected, VC11 and VC10 were connected, and the single-cell power consumption of VC14, VC12, and VC10 was twice that of other single-cell connected cells.
    I did not find the data of single-cell power consumption in the product specification, so I want to know this part of information. Can you help provide it? Thank you.

  • Hello,

    An increase in power consumption is normal. However, we currently do not have any documentation to support this.
