Abstract
A power sourcing equipment includes a control logic circuit and current source circuits that are coupled to a powered device via first and second wire pairs of a network cable respectively. The control logic circuit controls one of the current source circuits to drain a current from the powered device via the first wire pair during a first interval, to detect a first voltage of the first wire pair and a second voltage of the second wire pair, and controls the current source circuits to respectively drain currents from the powered device via the first and the second wire pairs during a second interval, to detect a third voltage of the first wire pair and a fourth voltage of the second wire pair, and determines whether the powered device is a single signature or a dual signature according to the first to the fourth voltages.
