USB Power Delivery and Type-COverview Architecture Product PortfolioSolution USB Type-C OverviewUSB Power Delivery specification introduces USB Type-C receptacle, plug and cable; they provide a smaller, thinner and more robust alternative to existing USB interconnect. Main features are: Enable new and exciting host and device form-factors where size, industrial design and style are important parameters Work seamlessly with existing USB host and device silicon solutions Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation USB Type-C Overview Enable newand exciting host and device form-factorswhere size, industrial design and style are important parameters Work seamlesslywith existing USB host and device silicon solutions Enhance ease of use for connecting USB devices with a focus on minimizing user confusion for plug and cable orientation Simple Power Delivery implementation (BMC) Type-C FeaturesMode of OperationNominal VoltageMaximum CurrentNotesUSB V500 mADefault current, based on definitions in the base specificationsUSB V900 mAUSB BC VUp to ALegacy chargingUSB Type-C @ A5 ASupports highpower devicesUSB Type-C @ A5 V3 ASupports higher Power devicesUSB PDConfigurable up to 20 VConfigurable up to 5 ADirectional control and Power level managementThe Re-Evolution of USBUSB has evolved from a data interface capable of supplying limited Power to a primary provider of powerwith a data interf
The Protocol Layer. forms the messages used to communicate information between a pair of ports. It receives inputs from the Policy Engine indicating which messages to send and indicates the responses back to the Policy Engine. Policies. Protocol Layer. It is responsible for sending and receiving messages across either the V BUS or CC wire.
