All rights reserved. viiiIntroduction This introduction is not part of IEEE Std 1823-2015, IEEE Standard for Universal Power Adapter for Mobile Devices.
44、 This standard focuses on a generic power adapter designed for reuse across brands, models, and years. A compliant adapter will supply a nominal 21 V at up to 130 W and may negotiate voltages up to 60 V at power levels up to, but less than, 240 W. Each power adapter will have one or more power ports
45、 to service load devices with control of each port via a serial communications link, an electrical variant of the CAN bus standard. Input power may be ac or dc depending on the market being served. A group of laptop, notebook, and other computing device, entertainment, and gaming system manufacturer
46、s approached the Microprocessor Standards Committee to define a common connector configuration, a power specification, and a communications protocol for a reusable durable power adapter system. This standard is the result of the foresight of that group. IEEE Std 1823-2015 defines a power delivery an
47、d communication connection between a power adapter and a power-using device greater than 10 W up to, but less than, 240 W range. The communications are used to coordinate the power delivery and provide identification between the power adapter and the power-using device. While primarily intended for
48、portable computing and entertainment devices, this standard applies to adapters serving other mobile devices in use around the office, home, or vehicle. To enable the powering of a wider class of low-cost devices, low-power devices with no communications capabilities are also supported under this st
49、andard. To Bob Davis, for his leadership, contribution, and dedication to better the standards and computing practice. Contents 1.
