Sehe ich das richtig, dass das nicht funktioniert?

Zitat:The Problem at PFI is, that the trip-poin scales with PVCC, so this input works only for one voltage atm. As the z-diode keeps VDD at ~the same level, undervoltage at this pin gets only detected when PVCC is at ~4.5V which is the minimum PVCC, SDZ needs to be pulled low before.

To my understanding, it wont work this way.

The "only" thing you have then, is 200ms startup delay and FAULTZ clearing (which also works with SDZ/FAULTZ tied together).
