Abstract
Apparatuses are provided for adapting USB, Thunderbolt, and similar connections to an Ethernet connection with dynamic multiplex power supply. The apparatuses of this disclosure are adapted to connect and power a peripheral device via its Ethernet port from a USB, Thunderbolt, or similar connection of a host computer. A power multiplexer is utilized in conjunction with a current detection circuitry and a PoE enable logic block to provide and regulate dynamic multiplex power supply from a multiplicity of power sources including an external direct current and a USB or Thunderbolt connection from a host computer.
