Abstract
Power over Ethernet (PoE) communication systems, control circuits and methods are presented for controlling power delivered to a powered device through a communication cable, in which a power sourcing equipment measures a supply voltage and selectively discontinues provision of power from a power source in response to a measured supply current exceeding an adaptive limit signal representing a supply current level corresponding to a predetermined safe operating power level at the measured supply voltage.
