In order to enable the object, technical solutions and advantages of the present invention become apparent, it is described in detail below with reference to accompanying drawings
An exemplary embodiment of the present invention.Note that in the present description and drawings, there is substantially the same step and element phase
Same appended drawing reference will be omitted the repetition of explanation of these steps and element to indicate.
Obviously, described embodiment is only a part of the embodiments of the present invention, rather than whole implementations of the invention
Example.Mentioned " one embodiment " or " embodiment " means the spy in conjunction with described in the embodiment to this specification in the whole text
Determine feature, structure or characteristic is contained at least one described embodiment.Therefore, phrase " is implemented at one in the description
Example in " or the appearance of " in one embodiment " be not necessarily all referring to the same embodiment.In addition, the special characteristic, structure or spy
Property can be combined in any suitable manner in one or more embodiments.It should be understood that the present invention is not shown by described herein
The limitation of example embodiment.Based on the embodiment of the present invention described in the disclosure, those skilled in the art are not paying creativeness
Obtained all other embodiment should all be fallen under the scope of the present invention in the case where labour.
Fig. 1 shows the schematic structure of the circuit structure according to an embodiment of the present invention for being applied to an electronic equipment 100
Block diagram, generally, as shown in Figure 1, the electronic equipment 100 may include current detector 110 and Universal Serial Bus Interface
Controller 120.
Specifically, the current detector 110 of electronic equipment 100 can connect the universal serial bus in the electronic equipment
Between interface and Universal Serial Bus Interface controller 120, for detecting the charging current in the Universal Serial Bus Interface.
Generally, current detector 110 can be a current sense resistor, be connected on the pin of the USB_5V of USB interface, with inspection
It surveys USB interface and is in charged state or data transmission state.
Universal Serial Bus Interface controller 120 can be used for examining the 110 charging electricity measured according to the current detector
Stream size is configured the state of the Universal Serial Bus Interface of the electronic equipment.Specifically, in a reality of the invention
It applies in example, the Universal Serial Bus Interface controller 120 of electronic equipment 100 may further include charge controller.If outer
The system that portion's equipment is connected to the electronic equipment 100 and the electronic equipment 100 by the Universal Serial Bus Interface
Into sleep state, then when the Universal Serial Bus Interface controller 120 judges the charging that the current detector detects
When current value is greater than first threshold, the state of the Universal Serial Bus Interface of the electronic equipment is arranged the charge controller
For quick-charge state.Generally, it is connected to the external equipment of electronic equipment 100 by USB interface, is set if not charging
It is standby, such as the external equipment is the external input devices such as keyboard, mouse, at this point, the electric current on the pin of the USB_5V of USB interface
Value is usually 40-50mA, does not exceed 100mA generally, if the external equipment is storage equipment, such as USB flash disk or USB interface
Mobile hard disk etc., when electronic equipment 100 is in sleep state, the current value on the pin of the USB_5V of USB interface is usual
It is not more than 100mA.As a result, in one example, the first threshold can be set to 100mA, at this point, when system enters
After dormant state, serial bus interface controller 120 can detecte the current value on the charging pins of the USB_5V of USB interface,
When the current value is greater than 100mA, it can determine that be connected to the external equipment of electronic equipment 100 by USB interface sets for charging
Standby, serial bus interface controller 120 can be by its internal charge controller by the USB interface of electronic equipment 100 at this time
State be set as quick-charge state.
At this point, in one embodiment of the invention, when the charge controller is by the general string of the electronic equipment 100
When the state of row bus interface is set as quick-charge state, if the external equipment supports Universal Serial Bus Interface fast charge

Current value, when serial bus interface controller 120 is arranged by its internal charge controller by the general string of electronic equipment 100
When the state of row bus interface is set as quick-charge state, if being connected to the outer of electronic equipment 100 by USB interface at this time
Portion's equipment supports fast charge mode, then charge controller is successful by the state of the Universal Serial Bus Interface of the electronic equipment 100
It is set as quick-charge state.On the other hand, after system enters dormant state, serial bus interface controller 120 detects USB
Current value on the charging pins of the USB_5V of interface and by its internal charge controller setting by electronic equipment 100
After the state of Universal Serial Bus Interface is set as quick-charge state, electricity is connected to by USB interface if detected at this time
The external equipment of sub- equipment 100 does not support fast charge mode, then charge controller is by the universal serial bus of the electronic equipment 100
The state of interface is set as the normal charging mode that charging current is less than quick-charge state.
In addition, in one embodiment of the invention, if external equipment is connected by the Universal Serial Bus Interface
System to the electronic equipment 100 and the electronic equipment 100 enters sleep state, then when the universal serial bus connects
When the charging current value that mouth controller 120 judges that the current detector 110 detects is not more than first threshold, the general string
The state of the Universal Serial Bus Interface of the electronic equipment 100 is set data transmission shape by row bus interface controller 120
State.For example, in one example, first threshold can be set to 100mA, at this point, after system enters dormant state, it is serial total
Line interface controller 120 can detecte the current value on the charging pins of the USB_5V of USB interface, when the current value is not more than
When 100mA, it can be determined that by the external equipment that USB interface is connected to electronic equipment 100 be not charging equipment, for example, can be with
It is external input device or External memory equipment etc., at this point, serial bus interface controller 120 can filling by its inside
Electric controller, which is arranged, transmits power mode for the condition setup data of the Universal Serial Bus Interface of electronic equipment 100, guarantees that USB connects
The data pin of mouth is in the state of normal ON and work, and entering after sleep state to prevent locking system can not support to pass through USB
The case where functions such as external input or the data transmission of interface.
