Abstract
A power sourcing equipment (PSE) exhibiting a low power sleep mode, the PSE constituted of: a sleep control circuitry comprising a first timer; an effective resistance threshold detector responsive to the sleep control circuitry and arranged to detect whether the effective resistance across the output port of the PSE is less than a predetermined threshold; and a detection and powering circuitry responsive to the sleep control circuitry, wherein the sleep control circuitry is arranged to load the first timer with a first predetermined time period, and at the expiration of the first predetermined time period: activate the effective resistance threshold detector for a second predetermined time period; and in the event the effective resistance threshold detector detects that the effective resistance across the output port of the PSE is less than the predetermined threshold, enable the detection and powering circuitry.
