| Zusammenfassung: | A local area networking apparatus comprises a power stage (420) for connecting to a network cable (430) for carrying carry power and data. The power stage (420) comprises a main current flow path (425) which includes a switch comprising at least one transistor (421) positioned in the main current flow path (425) and a current monitoring apparatus for monitoring current flow in the main current flow path, and wherein the current monitoring apparatus comprises a sensor (423) which is not placed in series with the main current flow path. The current monitoring apparatus can comprise a current mirroring stage which is arranged to mirror current flowing in the main current flow path to a monitoring current flow path. The switch can be implemented as a set of switches. |
