SuperSpeed USB 3.0 to Provide up to 100 Watts of Power
The USB 3.0 Promoter Group recently announced that they are creating a new power delivery specification which will significantly extend the capabilities and usages of cable bus power in USB applications. One of the new features that everyone is talking about it the higher voltage and current rating for USB 3.0 that allows a power draw of up to 100 Watts! This means that you can charge the battery of a notebook PC, or simply power a notebook PC while actively
using the USB 3.0 data connection would be possible on a desktop PC for example. Basically any device under 100 Watts. This really opens the door for USB 3.0 functionality and means that many more cool USB products will be coming out in the years to come!
Key characteristics of the forthcoming USB Power Delivery solution include:
- Compatible with existing cables and connectors
- Enables voltage and current values to be negotiated over the USB power pins
- Enables higher voltage and current in order to deliver power up to 100W
- Switchable source of power delivery without changing cable direction
- Coexists with USB Battery Charging 1.2 and works equally well with both USB 2.0 and USB 3.0
