Abstract:
1. A power adapter comprising: power conversion circuitry to receive AC power and provide DC power; detect circuitry for detecting a connection of an electronic device to a first wire and a second wire; power circuitry to provide the DC power over the first wire and ground over the second wire; and communication circuitry to receive first signals from the electronic device over the first and second wire and to provide second signals to the electronic device over the first and second wire, wherein the DC power provided by the power circuitry and the second signals provided by the communication circuitry are time-domain multiplexed such that the DC power is not provided by the power circuitry when the communication circuitry provides the second signals and the second signals are not provided by the communication circuitry when the DC power is provided by the power circuitry.
