Abstract
A system including a bus and a plurality of devices coupled thereto and configured to communicate with each other via the bus. The system further includes a power supply coupled to the bus, to power to the plurality of devices via the bus and to detect an event, and in response, alternately supply power to the plurality of devices via the bus at a first current level or at a lesser second current level. This allows additional devices to be used on a bus, even where the total power consumption of the devices would normally exceed a maximum defined by a bus architecture. This also helps allow a single gauge of wire to be used throughout a bus network (even where long lengths of wire are required) while still providing sufficient power to the devices connected to the bus.
