BQ27426: CONTROL_STATUS: SS is inverted

Part Number: BQ27426

Hi,

According to bq27426 Technical Reference (section 5.1.1 CONTROL_STATUS: 0x0000):

"SS = Indicates the fuel gauge is in the SEALED state. Active when set."

In my tests I saw the opposite behavior: SS bit is set when device is in UNSLEAD state, and cleared in SEALED state.

please advise.

Thanks,

Yaron

    Hello Yaron,

    Please provide more data of what you are seeing in the bit registers with screenshots or logged data. Most of the issues is looking at the wrong position in the bit array. When it is set the gauge should be sealed.

    Sincerely,
