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.

Description

Technical field [0001] This application relates to time-domain multiplexing of power and data. [0002] This application claims the benefits of U.S. Provisional Patent Application No. 61 / 482,195 filed on May 3, 2011, which is incorporated herein by reference. Background technique [0003] The type and number of electronic devices used by consumers have grown tremendously in the past few years, and the rate of growth has not shown any signs of slowing down. These electronic components include hand-held portable devices, such as notebooks, netbooks, or tablet computers, batteries, media, or smart phones, global positioning devices, media players, and other similar devices. [0004] These hand-held portable devices need to supply power during operation, and the power can come from external sources or internal sources, such as batteries. These batteries usually need to be charged with an external source (such as a power adapter). These power adapters can receive AC power from a wall p...
