A system according to various embodiments of the disclosure includes a bus and a plurality of devices coupled to the bus, the devices configured to communicate with each other via the bus. The system further includes a power supply coupled to the bus, the power supply for supplying power to the plurality of devices via the bus. The power supply is configured to detect an event, and in response to the event, alternately supply power to the plurality of devices via the bus at a first current level or at a second current level, the second current level less than the first current level. Among other things, embodiments in this disclosure help allow 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. Furthermore, various embodiments help 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. |
