  • Circuit and Method for Detecting a Legacy Powered Device in a Power over Ethernet System
    Publication number: 20110258464
    Abstract: In an embodiment, a power source equipment (PSE) device includes a network port configurable to couple to a network cable and a detection circuit coupled to the network port. The detection circuit is configured to apply a powered device (PD) detection voltage signal including first and second voltages to the network port and to sample a line current of the network port in response to the first and second voltages to detect a complex impedance indicating that a legacy PD is coupled to the network port.
