Title:
POWER SOURING EQUIPMENT CHIP, POWER OVER ETHERNET EQUIPMENT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/066063
Kind Code:
A1
Abstract:
A power souring equipment (PSE) chip, power over Ethernet (PoE) equipment and method, the method being capable of determining the access situation of a powered device (PD) of a corresponding terminal when powering with four cable pairs. PSE chip comprises a channel controller, a first channel detector and a second channel detector; the channel controller transmits a first detection voltage along a first group of cable pair in Ethernet twisted-pair cables via the first channel detector, and transmits a second detection voltage along a second group of cable pair in Ethernet twisted-pair cables via the second channel detector; and determining a first impedance according to the current detected by the first detection voltage and the first channel detector, and determining a second impedance according to the current detected by the second detection voltage and the second channel detector; and determining the first group of cable pair connected to an effective PD when the first impedance is within a preset range, and determining the second group of cable pair connected to the effective PD when the second impedance is within a preset range.
