Description
Technical field
The present invention relates to USB TYPE-C bypass functionality technical fields, specially a kind of USB TYPE-C PD bypasses charging
Circuit.
Background technology
With the development of USB connector, the USB connector USB Type-C of a new generation are proposed.The characteristics of new edition interface
It is that outward appearance is more slim, transmission speed power transmission capacity faster, more powerful and supports the positive and negative plugging function in two sides.USB
These new features of Type-C greatly improve the Consumer's Experience of traditional USB, support blindmate, are coordinating USB Power
The power transmission of highest 100W can be provided under the support of Delivery (USB PD) agreement.As USB Type-C have so
Powerful power transmission capacity, occurs in that a series of use USB Type-C interfaces headed by new edition MACBook on the market
PC, flat board, the product such as mobile phone.In order to meet the function of equipment quick charge, need to coordinate Type-C PD agreement realities
The power transmission of existing difference electric pressure.Type-C PD agreements can realize the appointing with 10mV as stepping of highest 20V in theory
Meaning voltage output, but PD electric pressures conventional at present are 5V, 9V, 12V, 15V and 20V.
Due to wideling popularize for USB Type-C products, and the requirements at the higher level to charging rate, occur in that Type-C PD
The portable power source of function.The portable power source of Type-C PD functions can be directed to different USB Type-C equipment and provide suitable electricity
Pressure, improves the charging rate to equipment.When portable power source input couple in adapter, while the output end of portable power source is accessed
Load, now then needs for the electric power of adapter directly to switch to portable power source for supporting the portable power source of bypass functionality
Output end is directly powered for load.The input output end voltage of traditional portable power source is all 5V, realize when the function be
Fairly simple.But the confession electric energy of the adapter of access can be followed as portable power source its input for supporting Type-C PD
Power is choosing a kind of suitable voltage, and the output end of portable power source then can be chosen different according to the different of the load for accessing
Supply voltage.Portable power source can be thus caused to there are a variety of electricity in its input and output end in independent discharge and recharge
Pressure grade.So for this input/output terminal all supports that the portable power source of PD functions needs to make input when bypass functionality is carried out
The electric pressure of output end matches the supply voltage that can just make load that safety is obtained from adapter end again, otherwise has and causes to bear
Carry the risk damaged.
In order to realize that the portable power source bypass functionality of PD functions is all supported in this input and output, can moved by software
Power input and output end carry out PD communications with adapter and load respectively, obtain voltage and electricity that adapter can be supported respectively
Stream ability and the receptible electric pressure of load end, are then matched by program synthesis and choose what a kind of adapter can be supported,
Load end is also receptible, is capable of the electric pressure of fast speed charging.Finally according to the electric pressure that program synthesis matching is obtained
PD acquisition requests are carried out to the electric pressure of the matching to adapter again, while again will be to being adapted to the communication of load end again PD
Device application is supplied to load to voltage, completes bypass functionality.PD communications are repeatedly carried out with adapter and load based on this software
Carry out that realization requirement of the mode of electric pressure adjustment to software is very high, any failure for once communicating is required for extra software
Mistake proofing mechanism is corrected, and stability compare it is relatively low.USB Type-C release also soon, the various adapters of PD functions and
Load is all not necessarily according to PD agreement strict implements, therefore will support various suitable when making to carry out bypass functionality in this way
Orchestration and load or presence are very big probabilistic, cause the reduction of portable power source Products Compatibility.By software repeatedly with
The mode that adapter and load PD communications obtain bypass voltage is high to software requirement in realization, and stability and compatibility all compare
It is low.
The content of the invention
It is an object of the invention to provide a kind of USB TYPE-C PD bypass charging circuit, to solve above-mentioned background technology
The Type-C PD bypasses of middle proposition are big, compatible than relatively low problem to software requirement height, enforcement difficulty.

Switch S1 and CC signal shift switch S2 are arranged in a crossed manner in portable power source input CC pin and portable power source output end CC pin for switching
Between.
Preferably, the portable power source input is provided with resistance Rd1 and resistance Rd2, and described resistance Rd1 one end is connected with MCU
Connect, the other end is connected with portable power source input by switching S5, and described resistance Rd2 one end is connected with MCU, and the other end is by opening
Close S6 to be connected with portable power source input.
Preferably, it is electrically connected between the adapter and portable power source input, and adapter is defeated with portable power source
Enter end and collectively constitute adapter access detection module.
Preferably, be electrically connected between the portable power source output end and load end, and portable power source output end with it is negative
Carry end and collectively constitute output loading access detection module.
Compared with prior art, the invention has the beneficial effects as follows：The realization of the USB TYPE-C PD bypass functionalitys by
Whether Type-C Source ends are detected by detecting CC signals has Sink equipment to access, and actively can initiate after detecting access
PD communications provide power supply grade suitably, quickly, safe for Sink, by portable power source MCU and peripheral detection module inspection
After adapter and load are measured while accessing, CC signals and shifting that portable power source input detecting adapter is accessed are each turned off
Then the CC signals of adapter end are directly connected to by the CC signals that dynamic power output end detecting load is accessed by switching switching
Load end, realizes connection of the adapter directly with load, and independently of portable power source, such adapter just necessarily can be successful
PD communications are carried out with load, and provide receptible, fast and safely charging voltage grade for load, processed by this scheme
The forward process of PD agreements need not be carried out by portable power source in adapter end and load end, the soft of enforcement is greatly reduced
Part difficulty, while making stability, compatibility all increase significantly in terms of also having security.
