By adopting the computer USB port charging control circuit, two charging modes for charging mobile equipment through a notebook computer USB port are provided for a user, and the user can select a proper charging mode to reduce unnecessary power consumption, thereby saving electric energy and reducing waste; and when the equipment is required to be charged overnight, energy-saving effects are more remarkable.
Description
Technical field
The utility model relates to field of computer technology, relates in particular to a kind of computer USB port charging control circuit.
Background technology
Mobile device has mostly been supported to charge through USB (Universal Serial BUS) port at present; But the USB interface of most of notebook computer all adopts+the electricity power supply of V5S system; The only a few computer can adopt+V5AL (Standby power supply) power supply, the power consumption when shortcoming of employing+V5AL power supply is system standby; And with+the electric words of supplying power of V5S system; Computer can't be given equipment charge again under dormancy, sleep or off-mode; Domestic consumer gives charging of mobile devices through the USB interface of notebook computer if desired; Just need make notebook computer be in normal operating conditions, both expend electric energy more, bring inconvenience again.
The utility model content
The purpose of the utility model is to provide a kind of computer USB port charging control circuit; It can be the user provides two kinds to be the charge mode of charging of mobile devices through the notebook computer USB port; The user can reduce unnecessary power consumption through selecting suitable charge mode for use; Thereby the saving electric energy cuts the waste.
For realizing above-mentioned purpose; The utility model provides a kind of computer USB port charging control circuit, and it comprises: input supply terminal ,+the V5S power supply ,+V5AL power supply, USB port, be electrically connected at USB port and+a MOSFET between the V5S power supply, be electrically connected at USB port and+the 2nd MOSFET between the V5AL power supply and be electrically connected at input supply terminal and a MOSFET and input supply terminal and the 2nd MOSFET between toggle switch.
Be respectively equipped with first pin, second pin and the 3rd pin on the said toggle switch; First pin electrically connects a MOSFET; Second pin electrically connects the 2nd MOSFET; The 3rd pin electrically connects the input power supply, and this toggle switch has the key of stirring, and stirs logical first pin of keyed jointing and the 3rd pin or second pin and the 3rd pin through this.
The beneficial effect of the utility model: the computer USB port that the utility model provides is to the application of charging of mobile devices; Stir through toggle switch and to realize that a MOSFET or the 2nd MOSFET open output, make+the V5S power supply or+V5AL exports to USB port, for USB port provide+V5S or+two kinds of electric source modes of V5AL; Thereby for the user provides two kinds to be the charge mode of charging of mobile devices through the notebook computer USB port; The user can reduce unnecessary power consumption through selecting suitable charge mode for use, thereby saves electric energy, cuts the waste; When needs were given equipment charge whole night, energy-conservation effect was more obvious.
In order further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through embodiment the utility model, the technical scheme that makes the utility model and other beneficial effect is obvious.
In the accompanying drawing,
Fig. 1 is the circuit theory diagrams of the utility model computer USB port charging control circuit.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with the preferred embodiment and the accompanying drawing thereof of the utility model.
As shown in Figure 1; The utility model provides a kind of computer USB port charging control circuit, and it comprises: input supply terminal (+VDC) 1 ,+the V5S power supply ,+V5AL power supply, USB port 10, be electrically connected at USB port 10 and+a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor metal-oxide half field effect transistor) 20 between the V5S power supply, be electrically connected at USB port 10 and+the 2nd MOSFET30 between the V5AL power supply and be electrically connected at input supply terminal and a MOSFET20 and input supply terminal and the 2nd MOSFET30 between toggle switch 40; The corresponding respectively control+V5S power supply of the one MOSFET20 and the 2nd MOSFET30 reaches+and the V5AL power supply exports to USB port; Stir through toggle switch 40 and to realize that a MOSFET20 or the 2nd MOSFET30 open output, make+the V5S power supply or+the V5AL power supply is to USB port 10 outputs.This input supply terminal is the input power supply that power supply adapter for notebook computer inserts to be provided behind the direct supply.
Further; Be respectively equipped with the first pin A, the second pin B and the 3rd pin C on this toggle switch 40; The first pin A electrically connects a MOSFET20, and the second pin B electrically connects the 2nd MOSFET30, and the 3rd pin C electrically connects the input power supply; This toggle switch 40 has the key of stirring 42; Stir key 42 through this and connect the first pin A and the 3rd pin C or the second pin B and the 3rd pin C, make a MOSFET20 or the 2nd MOSFET30 open output, thereby make+the V5S power supply or+the V5AL power supply exports to USB port 10.
For the utility model, no matter the DIP switch places arbitrary state in the daily use of user, can be not influential to the user.But when the user need not use computer; And need charge to mobile device through USB port the time, promptly can insert under the off-mode of power supply adaptor at computer, give charging of mobile devices through this DIP switch selection+V5AL power supply; Even if system gets into sleep, off-mode; Also can easily switch, when needs were given equipment charge whole night, energy-conservation effect was more obvious.
In sum, the computer USB port that the utility model provides is to the application of charging of mobile devices, stirs through toggle switch and realizes that a MOSFET or the 2nd MOSFET open output; Make+the V5S power supply or+V5AL exports to USB port; For USB port provide+V5S or+two kinds of electric source modes of V5AL, thereby for the user provides two kinds to be the charge mode of charging of mobile devices through the notebook computer USB port, the user can reduce unnecessary power consumption through selecting suitable charge mode for use; Thereby saving electric energy; Cut the waste, when needs were given equipment charge whole night, energy-conservation effect was more obvious.
The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technical scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection domain of the utility model claim.
