Other Parts Discussed in Thread: BQSTUDIO

Found another discrepancy in the TRM (I think).

Page 143 lists the bit fields for Manufacturing Status Initialization. It shows bit 5 as LED_EN and bit 9 as Reserved.

But Battery Management Studio shows bit 5 as LF_EN and bit 9 as LED_EN, the same as Manufacturing Status.

I assume that BMS is correct?

The Manufacturing Status Init register bit assignments in the TRM need to be corrected. The Manufacturing Status registers in the TRM and bqStudio program are correct. The Manufacturing Status Init register bit assignments in bqStudio are also correct.

Thanks, Tom.

Does the same issue exist with Charging Status? That it's incorrect in the TRM but correct in bqStudio?

(TRM doesn't show the SU flag.)

The SU flag is in the TRM. Reference page 189.
