Redundant system power supply

Thread Summary

The user seeks an ideal diode for power supply redundancy without current sharing, specifically for voltages above 40V. The final answer states that the LTC4418 is the highest voltage prioritizer in the ADI portfolio, but ideal diodes can be used for redundancy based on voltage alone, not priority. No specific alternative products or reference circuits were provided.

Hello.
I am looking for the ideal diode for power supply redundancy.
For redundancy I basically want to use one power supply. I do not want to do current sharing.
There are Prioritised PowerPath Controllers like the LTC4418, but I cannot select it because the system power supply is above 40V.
Is there an ideal diode that can prioritise the power path like the LTC4418?
Also, could you please provide any reference circuits?
