The Texas Instruments Power over Ethernet support a number of input voltage ORing options including highest voltage, external adapter preference and PoE preference. These features allow the designer to determine which power source will carry the load under all conditions. The PoE interface features the new extended hardware classification necessary for compatibility with high power midspan power sourcing equipment.
