Abstract
In a Power over Ethernet (PoE) system, a Powered Device (PD) having circuitry to measure the load current from a Power Sourcing Equipment (PSE) in the PD. Circuitry compares the measured load current with a first threshold. Circuitry automatically generates load pulses for signaling the PSE. The pulse widths of the load pulses are measured and the widths are automatically adjusted, that power to the PD should be maintained.
