Survey unit to be monitored resulting supply voltage and electric current, monitoring information feeds back to MCU control unit,
After voltage x current is normal, MCU control unit control metal-oxide-semiconductor array element, according to power bus interface
Magnitude of voltage corresponding to line sequence matches docking to carry out, and the voltage needed for output, the power bus of this version connects
Mouth can carry out flexible configuration by communication interface, i.e., the dynamic power supplies demand according to objective chip can be flexible
Configuration power bus interface and intelligent power output.
As shown in figure 3, be a kind of application connection block diagram of pattern intelligent power design once, using this connection
The power bus interface of mode can be the actual demand flexible configuration according to chip.
Selected chip interface type difference when being based on board design of connected mode described in Fig. 3, and it is various
Power bus interface has the demand of dynamic configuration, needs intelligent power to be carried out with objective chip in application process
Communication, obtains the parameters such as chip power demand, dynamic regulation voltage, under this scene, the electricity of chip in real time
Source demand is change, it is desirable to which each power bus interface of intelligent power can only connect an objective chip.
As shown in figure 4, be the workflow of intelligent power under above-mentioned scene, it is of the present invention in practical application
Intelligent power be connected with the power input interface of circuit board, in circuit board general supply electricity after, intelligent power is opened
Beginning work, by the communication interface in the power bus interface of intelligent power come the data storage for objective chip
Device is powered and obtains the data of power supply requirement, and the data of power supply requirement include different voltage, required electric current,
The electric sequence of each voltage.When the MCU control unit in intelligent power correctly recognizes the power supply of objective chip
After demand, program control voltage regulation unit is controlled to carry out voltage stabilizing output according to power supply requirement, if without correctly recognizing mesh
The power supply requirement for marking chip then continues to read, and parses data.The output of program control voltage regulation unit is connected to power supply prison
Survey on unit, can be fed back to when supply voltage and the correct port number of output that power supply monitoring unit is monitored
MCU control unit, MCU control unit controls metal-oxide-semiconductor array element to adjust matching somebody with somebody for power bus interface
Put, i.e., power bus passage is matched with supply voltage according to chip power.If power supply monitoring unit
Monitoring result is abnormal, then feed back to program control voltage regulation unit, is adjusted, and metal-oxide-semiconductor array element does not do matches somebody with somebody
Put, also do not export externally.

Under enter row bus mounting, i.e., multiple objective chips are mounted on one power bus.
Under the pattern, the MCU control unit in intelligent power is configured directly with each type power bus and connects
The power consumption signatures of mouth, including supply voltage and electrifying timing sequence etc..Electricity of the MCU control unit according to configuration
Source demand come control program control Voltage stabilizing module obtain multichannel difference magnitude of voltage voltage, power supply monitoring unit is to gained
To supply voltage and electric current be monitored, monitoring information feeds back to MCU control unit, and voltage x current is normal
Afterwards, MCU control unit control metal-oxide-semiconductor array element, according to power bus interface line sequence corresponding to
Magnitude of voltage matches docking to carry out, the voltage needed for output.
In another embodiment of the present invention, it is contemplated that every power supply requirement of power bus in the case of pattern two
It is fixed, so, the function of MCU administrative units can be issued, you can single so that MCU management need not be laid
Unit.Now, power supply processing module includes DC-DC power source unit, program control voltage regulation unit, power supply monitoring unit

DC-DC power source unit is that conversion process is carried out to the Width funtion of outside input in such scheme, exports 5V
Or 12V etc., program control voltage regulation unit carries out the voltage that DC-DC power source unit is exported according to the parameter for setting
Treatment output, output is connected with power supply monitoring unit, and the comparator unit inside power supply monitoring unit will be gathered
The voltage come in is compared with voltage reference, will gather the electric current come in and is compared with the excessively stream thresholding of setting
Compared with the Shi Caihui that all meets the requirements opens passage according to the state modulator metal-oxide-semiconductor array for setting, to power supply
EBI output voltage.
The described parameter for setting is determined by the type of power bus interface, and different power bus connect
The type of mouth has fixed output voltage species, peak power output, electrifying timing sequence of each voltage etc..
As shown in figure 5, a kind of practical application connection diagram under for above-mentioned scene, it would be desirable to the core of power supply
Piece is directly connected on intelligent power by power bus, and the power bus interface type of objective chip must be with
The power bus interface connection of the corresponding same type of intelligent power, the total work of the chip connected in bus
Consumption is limited no more than every road port maximum power dissipation of intelligent power, preferably reserves certain surplus, is prevented
Because the power consumption fluctuation of chip causes total power consumption to exceed thresholding, intelligent power is caused to enter protection off-position.
A kind of another application scenarios of intelligent power design are illustrated in figure 6, intelligent power supports multiple power sources
EBI type, therefore intelligent power actual design can also connect according to power, different types of power bus
Mouthful number defines different types of intelligent power.
The present embodiment description is a kind of Smart Power Module applied field for supporting polytype power bus interface
Scape, the different types of interface of each of power bus can be configuration as shown in the figure, according to actual mesh
Mark chip demand to be configured, such as power bus type A, B, C connect a target IC respectively, this
The power supply requirement of a little target IC is different, or have special demands, it is necessary to carry out independent control.Electricity
Multiple target IC are connected on source bus type D interface, there is these targets IC identical power bus to connect
Mouthful, peak power output of the objective chip total power consumption less than the power bus passage of intelligent power.Intelligence electricity
Each power bus interface passage in source can be independently to control.
