Abstract: Circuits, methods, and apparatus that may allow an electronic device to control a power adapter. One example may provide an electronic system where an electronic device may control a power adapter through a communication channel. Data transferred in the communication channel may include the temperature of the power adapter, the charging capability of the adapter, and other types of data. In one example, power and data may share the same two wires, and the power and data may be time-division multiplexed. That is, the two wires may convey power and data at different times. Another example may include circuitry to detect a connection between the electronic device and the power adapter. Once a connection is detected, power may be transferred from the power adapter to the electronic device. This power transfer may be interrupted on occasion to transfer data between the power adapter to the electronic device.

Abstract translation: 可允许电子设备控制电源适配器的电路，方法和设备。 一个示例可以提供电子系统，其中电子设备可以通过通信信道来控制电力适配器。 在通信信道中传送的数据可以包括电源适配器的温度，适配器的充电能力以及其他类型的数据。 在一个示例中，功率和数据可以共享相同的两条线，并且功率和数据可以被时分复用。 也就是说，两条线可以在不同时间传输电力和数据。 另一示例可以包括用于检测电子设备和电源适配器之间的连接的电路。 一旦检测到连接，电源可能会从电源适配器传输到电子设备。 这种电力传输有时可能会在电源适配器与电子设备之间传输数据。
