BQ76930: OV and UV_TRIP settings

Part Number: BQ76930

Hi Team,

I would like to set OV_TRIP and UV_TRIP registers before enabling ADC via [ADC_EN]. However "7.3.1.1.2 14-Bit ADC" section mentioned ADC will automatically enabled when START mode is enabled.

Should I set OV_TRIP and UV_TRIP registers after enabling START mode?

Regards,

    Hi Yamashita-san,

    There should be enough time to program the OV_TRIP and UV_TRIP registers even if the ADC is enabled because there is a default 1 second delay for the voltage protections. Additionally, the device will take at least 125ms before it takes the first voltage reading.

    Best regards,
    Matt
