BQ40Z50-R1: SUV

Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQ40Z50, BQSTUDIO

If I want to enable the SUV function in PF, the FUSE pin grounding of the BQ40Z50 chip is not used, and only Settings:Enabled PFA in the upper computer of BQStudio is set, the SUV is set to 1 and the SUV threshold is set to 2000mV. Do you need to configure anything else? Why does the FET not turn off when the cell voltage reaches below 2V?

    Hello,

    Is it possible to send a .gg file of the gauge settings and a log file of SUV attempting to be triggered by the gauge? This will allow us to pin point the reason the SUV protection is not triggering.

    Regards,
