    摘要: The present invention provides a method to at least partially power an Ethernet device from a plurality of balanced network power signals received through a network connection. This involves attaching the network device to the network, wherein network signals are received and contain both power signals and/or data signals. These network signals may be passed through surge protection and power-conditioning circuitry wherein the output of these circuits may be provided to a power absorbing circuit. This power absorbing circuit may separate the communication signal and power signal from the network signal. The communication signal may be passed to a network physical layer while the power signal may be passed to a power distribution module. Additionally, because certain embodiments may provide multiple pairs of network power signals to the power absorbing circuit, the current or power associated with each power signal must be sensed and balanced. This may be done with an active control circuit. The balanced power signals may then be supplied from the power absorbing circuit to the network-attached device in order to at least partially power the network-attached device.

    摘要: An interface between two or more integrated circuit devices employs isolation techniques to provide electrical isolation of a digital signal for transmission of the digital signal between a master device and one or more slave devices. Unidirectional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended direction is performed by direction control logic. Logic that monitors read and write transactions operates to determine a desired direction of the digital signal and accordingly directs the digital signal through an appropriate isolator channel.

    摘要: Power feed circuitry within a power over Ethernet (PoE) device detects fault conditions within power and data distribution lines coupled to the power feed circuitry. This circuitry includes network interface circuitry coupled to the network in order to exchange both data and power signals. The power interface circuitry also communicatively couples to at least one isolated power supply in order to draw power. The power may then be distributed via the attached network interface circuitry. A fault detection module couples to the power interface circuitry and the network interface circuitry. This fault detection module senses fault conditions associated with the power interface circuitry, network interface circuitry, and associated distribution lines in order to better draw and distribute power signals using the power feed circuitry.
