Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is carried out clearly
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this
Bright a part of embodiment rather than all embodiment, based on embodiments of the invention, those skilled in the art is not paying
Other embodiments obtained on the premise of creative work, belong to the scope of protection of the invention.
The circuit structure of the high-voltage high-speed charging of many mouthfuls of a kind of multiplexing single supply output, connects including power supply source and power supply source
The high-voltage high-speed charge port module connect, also includes controlling logic module, PMOS, PMOS driving module, inserting detection module
With dial-out detection module.
The present embodiment, on the basis of existing high-voltage high-speed charger, adds PMOS M1, PMOS driving, inserts
Detecting and extract detection, new control logic controls the break-make of PMOS and the output of power supply source according to the input of newly-increased module
Voltage.
Control logic module, and insert detection module and transfer to detection module communication, and detect according to the insertion that receives
The information of module and dial-out detection module controls break-make and the output voltage of power supply source of PMOS, controls the realization of logic module
Mode can be multiple.
As shown in Figures 2 and 3, PMOS drives module, for according to the control logic control PMOS controlling logic module
The switch of pipe, what the PMOS of the present embodiment drove module is designed as two kinds but be not limited in the present embodiment two kinds, and Fig. 2 is one
Planting push-pull configuration, M3 is responsible for the pull-up of M1 tube grid (gate), and M2 is responsible for the drop-down of M1 tube grid (gate)；M2 in Fig. 3 bears
Duty M1 tube grid (gate) is drop-down, and R1 is responsible for M1 tube grid (gate) pull-up.
PMOS, for driving the instruction of module to control the break-make of described common charge port power path according to PMOS；
When high-voltage high-speed charge port voltage is non-5V, PMOS disconnects；When high-voltage high-speed charge port voltage is 5V, PMOS is beaten
Open.
Insert detection module, detect whether common charge port has charger to connect for the switch conditions according to PMOS
Enter；When PMOS turns off, insert detection module and detect whether common charge port has equipment to access, if having equipment to access, then
The transmission insertion successful signal of detection, to controlling logic, as shown in Figure 4, gives and inserts the possible implementation of one detected.
Current source charges first to output capacitance C2, when capacitance voltage is higher than certain value, and such as 3V, the switch in turn-off current source, so
The floating electricity of certain voltage is had on electric capacity.During work, terminal unit is once had to insert LV mouth, then owing to electric charge is shared, on C2
Voltage can fall low moment, and logic circuit detects trailing edge, is sent to control logic circuit.Insert the embodiment of detection module
Have multiple, the most do not affect structural implementations in the present invention.
Extract detection module, for detecting the load current of common charge port when PMOS turns on, if LV equipment pulls out
Going out, load current becomes zero, sends and extracts the successful signal of detection to controlling logic.
Fig. 5 and Fig. 6 is the implementation extracting detection module, inspection leakage resistance is serially connected in power flow, by detection
The height of resistance Rcs both end voltage difference extrapolates the size of LV mouth electric current, thus judges that LV equipment has been extracted.According to
The position of inspection leakage resistance, mainly can list following two implementation:
Fig. 5 is to extract the implementation that the inspection leakage resistance of detection is held with being connected on；
Fig. 6 is that the leakage resistance of examining extracting detection is connected on the implementation of outfan.
Fig. 7 is the implementation utilizing the dead resistance of PMOS to realize extracting the inspection leakage resistance needed for detection, so
Inspection leakage resistance can be reduced, reduce cost, improve the conversion efficiency of circuit power.
Control logic module to drive the input of module respectively with power module input, PMOS, insert detection mould
Block outfan connects with extracting detection module outfan, and PMOS drives the outfan of module to connect PMOS grid, PMOS
Source electrode connects power supply source outfan, and PMOS drain electrode connects the input inserting detection module, inserts the input of detection module
Common charge port module is connected with extracting detection module.
Table 1 gives charger load and the condition diagram of each module.

Table 1.
Table 1 illustrates the circuit structure of specific embodiment of the invention modules under different charger load scenes
Situation, it will thus be seen that
LV mouth is only when access device, and PMOS just can open, and LV eloquence has the charging voltage of output about 5V, now HV
Mouth is not responding to the high pressure request of HV equipment.
LV mouth is not when having access device, and PMOS can turn off, and LV mouth does not has voltage to export, and now HV eloquence can set according to HV
Standby high pressure request adjusts the output voltage of HV mouth.
Only at LV mouth without equipment, and when HV mouth accesses HV equipment, HV eloquence can provide adjustable voltage, and other scenes are only
5V voltage can be provided, thus the safety realizing single supply is shared.
The control logic of the present embodiment table 1 explanation and a kind of implementation of state, as long as can security control PMOS
Be turned off and on, can reach single supply share purpose, can effectively protect again LV mouth to make its not overvoltage, can serve as close
The logic of reason is applied.
It should be noted that the above is presently preferred embodiments of the present invention, the invention is not limited in above-mentioned
Embodiment, as long as it reaches the technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
