Hi,
Our design uses LTC4212 for 3.3V ORing.
Current Rating: 4A (max)
Following MOSFET has been chosen for the design: Si6423ADQ / Vishay
Pl let us know if this MOSFET is good enough for the application?
Best Regards,
Pons

Hi,
Are you sure that you have the right part numbers?
The LTC4212 is a Hot Swap controller that requires an N channel MOSFET.
The Si6423ADQ is a P Channel MOSFET

Hi JayBee,
Apologies for the wrong PN. Correct PN is: LTC4412.

Pons,
Based on this graph from the MOSFET datasheet:
And the RDSon, the Si6423adq is a suitable MOSFET.
The forward voltage drop of the ideal diode will be around 60mV.

Thanks JayBee for the analysis & confirmation.
