A fully integrated circuit configuration that can be used to control the power path of a number of PMOS load switches is described. The circuit has a unique feature that it can automatically select the input voltage to be presented to the VOUT pin based upon the voltage levels at the respective VIN pins. By using combinations of the EN input pin and the SEL input pin, the circuit can be configured to perform one of four functional behaviors: 1. Complete shutdown (both switches in the OFF position), 2. Automatic input selection according the voltage levels that are presented on the VIN pins, 3. Selection of the VIN1 input only, or 4. Selection of the VIN2 input only. This concept is extended to multiple input sources in further embodiments.

Provided is a feedline branching apparatus that makes it possible for additional submarine cables to be installed easily, and with which cost increases can be restricted. For these purposes, the feedline branching apparatus comprises a branching unit and an earth unit. First, second and third terminal stations are connected to the branching unit via first, second and third cables, respectively. When the first and second cables are normal, the branching unit connects a feedline of the first cable to a feedline of the second cable, thereby forming a feedline using a first current. If one of the first and second cables is faulty, the branching unit grounds the feedline of the one of the first and second cables, while connecting the feedline of the other cable to the earth unit. The earth unit grounds a feedline of the third cable, thereby forming a feedline using a second current. When the feedline of the other cable is connected to the earth unit from the branching unit, the earth unit grounds the feedline of the other cable, thereby forming a feedline using the first current.
