Abstract

An adapter for providing a source of power to a mobile device through an industry standard port is provided. In accordance with one aspect of the invention, the adapter comprises a plug unit, a power converter, a primary connector, and an identification subsystem. The plug unit is operative to couple the adapter to a power socket and operative to receive energy from the power socket. The power converter is electrically coupled to the plug unit and is operable to regulate the received energy from the power socket and to output a power requirement to the mobile device. The primary connector is electrically coupled to the power converter and is operative to couple to the mobile device and to deliver the outputted power requirement to the mobile device. The identification subsystem is electrically coupled to the primary connector and is operative to provide an identification signal.

Claims (22)

1. An adapter comprising:

a USB VBUS line and a USB communication path,

said adapter configured to supply current on the VBUS line without regard to at least one associated condition specified in a USB specification.

2. The adapter of claim 1 , wherein said associated condition is a current limit.

3. The adapter of claim 1 , wherein said current is supplied without USB enumeration.

4. The adapter of claim 1 , wherein said current is supplied in response to an abnormal data condition on said USB communication path.

5. The adapter of claim 4 , wherein said USB communication path includes a D+ line and a D− line.

6. The adapter of claim 5 , wherein said abnormal data condition is an abnormal data line condition on said D+ line and said D− line.

7. The adapter of claim 6 , wherein said abnormal data line condition is a logic high signal on each of said D+ and D− lines.

8. The adapter of claim 7 , wherein each said logic high signals is greater than 2V.

9. The adapter of claim 2 , wherein said current limit is 500 mA.

10. An adapter comprising:

a USB VBUS line and a USB communication path,

said adapter configured to supply current on the VBUS line without regard to at least one USB Specification imposed limit.

11. The adapter of claim 10 , wherein said USB Specification imposed limit is a current limit.

12. The adapter of claim 10 , wherein said current is supplied without USB enumeration.

13. The adapter of claim 10 , wherein said current is supplied in response to an abnormal data condition on said USB communication path.

14. The adapter of claim 13 , wherein said USB communication path includes a D+ line and a D− line.

15. The adapter of claim 14 , wherein said abnormal data condition is an abnormal data line condition on said D+ line and said D− line.

16. The adapter of claim 15 , wherein said abnormal data line condition is a logic high signal on each of said D+ and D− lines.

17. The adapter of claim 16 , wherein each said logic high signal is greater than 2V.

18. The adapter of claim 11 , wherein said current limit is 500 mA.
