TPS22965-Q1: QOD at VBias = Low

Part Number: TPS22965-Q1

Hi team,

I would like to know if QOD function is active if Vbias and/or VIN is power down.

If it is not, could you advise the minimum voltage required to keep QOD active?

*assume ON pin is held Low.

I would like to know if the output discharges fast enough if VIN/Vbias accidentally drops when turning off the ON pin.

regards,

    Tsuji-san,

    The device is powered through the VBIAS pin. This means that QOD will only work as defined in the datasheet under the condition that VBIAS is over 2.5V.

    VIN voltage is of less concern than VBIAS for this device. 

    The output discharge time would depend on the amount of output capacitance on this rail.
