Part Number: BQ29209
Other Parts Discussed in Thread: BQ77307

Hello,

i'm using the BQ29209 with LiFePo4 (2S) cells and would like to know if it's possible to limit the threshold for Vprotect to 3.8V,

or do you have an alternative suggestion?

Best Regards!

Veysel

    Hi Veysel,

    I don't think we would be able to change the overvoltage threshold on the bq29209.

    If you do not need cell balancing, the bq771824 could be a suitable alternative, with an overvoltage threshold of 3.85V. Another possible alternative is the bq77307, which has functionality to allow for user configuration of the device.

    Regards,
