1. A circuit comprising:
- a physical arrangement of power transistors;
said circuit being adapted to couple a node to a power bus segment;
said physical arrangement of power transistors being electronically configurable, based on externally derived electrical signals, to sink power to the node from the power bus segment, source power from the node to the power bus segment, and distribute power through the node;
wherein said arrangement of transistors is also electronically configurable so that at least two power bus segments are capable of being coupled to the node and electronically isolated from each other at the node.
