摘要

A power source equipment (PSE) controller exhibiting low standby levels for power over Ethernet (PoE) comprises: a micro-controller; a detection and classification circuit coupled to the micro-controller to detect if a powered device (PD) is connected and determine power needed to operate the connected PD; and a power control and monitor circuit coupled to the micro-controller to supply power to the connected PD and monitor the power consumption of the PD. The detection and classification circuit and the power control and monitor circuit can be individually turned off by the micro-controller to minimize standby power and the micro-controller can be put into a deep sleep state if the PD is not detected or can be come out of the deep sleep state if the PD is detected.
