Hello,
The strength of RPD will get weak with low VIN. How weak will it be with VIN at GND? Will it be no strength, or RPD becomes infinite (open)?
8.3.3.1 QOD When System Power is Removed
The adjustable QOD can be used to control the power down sequencing of a system even when the system power supply is removed. When the power is removed, the input capacitor discharges at VIN. Past a certain VIN level, the strength of the RPD will be reduced. If there is still remaining charge on the output capacitor, this will result in longer fall times. For further information regarding this condition, see the Setting Fall Time for Shutdown Power Sequencing section.
Thank you.
