Abstract
A power delivery system includes a power sourcing equipment, a powered device and a transmission cable. When the power sourcing equipment is electrically connected to the powered device via the transmission cable, an over-current detecting circuit in the power sourcing equipment is configured to detect over-current occurrence of the powered device. Meanwhile, the power sourcing equipment is configured to determine the functionality of the over-current detecting circuit based on its specific pin and provide single fault protection when the over-current detecting circuit fails.
