The datasheet of LMQ61460-Q1 specifies the absolute maximum spec of Min=0V for PGOOD pin. It’s not allowed to get any negative voltage, unlike other pins (Min= - 0.3V). Also, the PGOOD can be grounded if not used.
A customer asks about this. The Min=0V means that it’s not allowed even for a bit negative voltage. In that case, if PGOOD is tied to GND, is there a possibility that any negative voltage will be applied with respect to GND? Otherwise, there will be no potential difference between PGOOD and AGND/PGND? Could you provide your opinion?
