This is a very basic article on safety circuits, somehow I thought it would be more in-depth on first sight. Well, I guess I would… with that dream I had and all.

This is a really good article about ideal diodes. Schottky diodes in power supplies for polarity protection or OR-ing together multiple power sources, like battery backup and AC line power? Sure, that works okay for low-current (and low-voltage) systems, but for high current systems, considerable energy is lost inside the Schottky diode due to forward conduction power loss and this can create considerable heat dissipation issues. Hence, this is the motivation for using “ideal diode” integrated circuit controllers since they have lower energy losses for switching high current loads.
