摘要： A power over Ethernet extender arranged to detect if power is received over 2 pairs of wires or over 4 pairs of wires. If power is received over 4 pairs of wires, power is output over only 2 pairs of wires. Preferably, the power signature of the received power is further detected. If the incoming power over a first 2 pairs of wires supports in excess of 13 watts of power consumption, and power is received over 4 pairs, then the output power supports in excess of 13 watts of power consumption; and if the incoming power over a first 2 pairs of wires supports in excess of 13 watts of power consumption, and power is not received over 4 pairs, then the output power does not support in excess of 13 watts of power consumption.

摘要： In a particular embodiment, a circuit includes a power supply, a ground, and a clamping transistor circuit coupled to the power supply and to the ground. The circuit further includes a disable clamp circuit. The disable clamp circuit is coupled to the power supply and is responsive to a second power supply input to selectively disable the clamping transistor circuit by modifying a charging current applied to a capacitor of the clamping transistor circuit. In a particular embodiment, modifying the charging current includes enabling a second charging path. Enabling the second charging path enables charging the capacitor at a higher charging rate than a charging rate associated with charging the capacitor via a first charging path.
