OR Controllers, Ideal Diodes

Ideal diode controllers, also called O-Ring controllers, are devices designed to control an external pass transistor (usually a FET) in a manner that allows current flow in only one direction, similar to a rectifier diode but with significantly lower conduction loss. Among other applications, they are commonly used for providing reverse-flow protection in power supplies designed to be connected in parallel for sake of redundancy or increased output current capability.
