Tool/software:
Hello,
We are using the BQ76942 in a custom configuration. Basically, we are just using it for cell balancing and not to control the charge and discharge FETs.
We have a 1mOhm sense resistor between the SRP and SRN pins.
The configuration for this sense resistor is the same as the simplified schematic on the first page of its spec sheet.
During Charging the SRP pins voltage is positive when compared to the SRN pin.
During Discharging the SRP pins voltage is negative when compared to the SRN pin.
From page 36 of the spec sheet (section 10.3) these results are correct.
The issue is cell balancing only occurs during discharge and does not occur during charging.
I have the Cell Balancing Configuration to allow cell balancing while charging and in Relax conditions.
I'm not looking to cell balance during discharge and want to cell balance during the charge mode.
Is there anything I can check that would cause/correct this issue?
Thanks,
Jim
