Summary of the invention
The technical problems to be solved in the utility model be to provide that a kind of interface is many, many grades of voltage exports and tool charging recognition function fill multiplex roles charger soon.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Fill multiplex roles charger soon, comprise at least two USB interface and power control circuit be set up in parallel, it is characterized in that: in described USB interface, having at least one can be, USB that mobile phone or flat board fill soon fills interface soon, it is 5V/2A, 9V/1.67A or 12V/1.2A that this USB fills interface power output soon, and remaining USB interface is generic USB interface.
Described power control circuit is provided with and fills booster circuit soon, and this fills booster circuit soon and is made up of the 11 inductance, the 5th metal-oxide-semiconductor, the 8th control boost chip and the tenth filter capacitor.
Described USB fills interface soon and meets QC2.0 & MTK and fill agreement soon.
It is one that described USB fills interface soon, and generic USB interface is four.
The chip of the described 8th controls boost chip to be model be MG26P701, the switching tube of described 5th metal-oxide-semiconductor to be model be SM8205A.
Compared with prior art, the multiplex roles charger that fills soon of the present utility model adopts at least two USB interface and power control circuit be set up in parallel, it is at least provided with one and can be the USB that mobile phone, flat board or other mobile terminal fill soon and fill interface soon in described USB interface, this USB fills interface power output soon and can automatically identify according to loadtype and export 5V/2A, 9V/1.67A or 12V/1.2A, and remaining USB interface is generic USB interface.
An integrated multiple voltage electric current of charger exports by the utility model, meets the demand of the most of charging device of family expenses.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the multiplex roles charger that fills soon of the present invention comprises casing and is arranged at the power control circuit in casing, it is provided with at least two USB interface side by side, wherein, USB that mobile phone, flat board or other mobile terminal fill soon fills interface 2 soon to have at least one can be, this USB fills interface 2 power output soon and can be 5V/2A, 9V/1.67A or 12V/1.2A and meet QC2.0 & MTK and fill agreement soon, maximum exportable 15W (high-power charging reduces the charging interval greatly).Remaining USB interface is generic USB interface 3, and each USB interface output current controls separately.
It is one that the utility model selects described USB to fill interface 2 soon, and generic USB interface 3 is four.USB fills interface 2 soon and is distinguished by identifying or use the USB glue core of different color especially with generic USB interface.
Power output in four generic USB interfaces 3 is a 5V/2.4A, two 5V/2.1A and 5V/1A respectively.Wherein, 5V/2.4A can be IPad charging, and 5V/2.1A can be common large-size screen monitors smart mobile phone and dull and stereotyped charging, and 5V/1A can be regular handset or other equipment charges.
As shown in Figure 5, the output current limiting of generic USB interface 3 adopts Current limited Control chip U4 to complete.Every two groups of outputs complete current-limiting function with a Current limited Control chip U4; when output current is larger time; the pressure drop of the parallel resistance that RS1 and RS1A of first group is formed also can become large; when voltage reaches the reference voltage of " SEN1 " pin of Current limited Control chip U4 time; " OUT1 " foot control system first switching tube Qsen1 of Current limited Control chip U4 turns off; thus block output voltage and electric current, the charging device of protection rear end.Also make often to organize separate output, one group of abnormal other group that do not affect exports.
Described power control circuit is provided with and fills booster circuit soon, and this fills booster circuit soon and is made up of the 11 inductance L 11, the 5th metal-oxide-semiconductor Q5, the 8th control boost chip U8 and the tenth filter capacitor EC10.
The chip of the described 8th controls boost chip U8 to be model be MG26P701, the switching tube of described 5th metal-oxide-semiconductor Q5 to be model be SM8205A.
Booster circuit operation principle of filling soon of the present utility model is as follows:
As in Fig. 4, fill booster circuit soon and 5V voltage is upgraded to the high voltage filling output soon, 11 inductance L 11 is energy storage inductor, when the 8th controls boost chip U8 driving the 5th metal-oxide-semiconductor Q5 unlatching, 11 inductance L 11 charging energy-storing, when the 8th control boost chip U8 cancels driving, the 5th metal-oxide-semiconductor Q5 turns off, 11 inductance L 11 releases energy and to superpose with 5V, makes USB fill interface output voltage soon and raises.
Output voltage is through R35 and R36 dividing potential drop, and input signal gives " FB " pin of the 8th control boost chip U8, and the 8th controls boost chip U8 according to the signal controlling obtained the 5th metal-oxide-semiconductor Q5 switch, thus control USB fills the height of interface output voltage soon.D+ and D-of USB gives the 8th to control boost chip U8 signal according to QC2.0 standard, and the 8th controls boost chip U8 adjusts " FB " pin reference voltage according to the signal that D+ and D-gives, thus change USB fills interface output voltage soon, reaches QC2.0 standard.When output current is larger; the presser feet that 25 resistance R25 is formed is larger; when pressure drop is greater than the 8th control boost chip U8 " Current_DET " pin detecting pin voltage; 8th controls boost chip U8 can close the 7th metal-oxide-semiconductor Q7; thus close output voltage and the electric current that USB fills interface soon, reach the effect of overcurrent protection.
