ABSTRACT:
A method and apparatus of powering components on a network by using a load-share technique and by using over-voltage and current-limiting circuitry. The power subsystem for a component in a network is designed in a load-share manner whereby the power subsystem will supply power to the network bus and to the component load. Under normal operation of the power subsystem, the load will be powered directly from the power subsystem. In the event of a failure, the load will immediately pull power from the bus and thereby maintain network operation. The power subsystem and the power supply are protected from disruptions due to voltage or current surges. Further, the power subsystem is in compliance with the IEEE 1394 specifications in terms of recommended current levels and galvanic isolation of the power sources.
