ABSTRACT:
A novel system for providing power over the Ethernet includes a current limit circuit for preventing an output current from exceeding a current threshold set at a prescribed level, and a foldback circuit for reducing the current threshold when an output voltage is lower than a prescribed voltage value. The foldback circuit may be controlled to operate in a high-power mode to increase the current threshold above the prescribed level.
