In embodiment of this case, the voltage of external power supply VO is providing the driving power needed for load block 101.It is younger
It carefully says, external power supply VO can be converted indirectly by power supply on vehicle and obtained or directly carried by other power supply unit
For.In addition, the voltage of the first power supply V1 gives detecting block 102 to provide driving power, and the first power supply V1 can be automobile-used
Power supply is obtained with a high voltage device (being, for example, the chip of T18 processing procedures) conversion output or is directly carried by other power supply unit
For.However, in other embodiments, the source of external power supply VO and the first power supply V1 are not limited to above-described embodiment.
It includes circuit appropriate, logic and/or coding to load block 101, and end ET inputs are input from the outside to receive
External power supply VO is to be driven.In embodiment of this case, load block 101 includes the physical layer that second is netted very much in auto electronic
(PHY layer) and the transmission module (being, for example, TX/RX modules) of network layer (MAC layer) or other functional circuits.So
And in other embodiments, load block 101 can also be implemented by circuits such as general load circuit or counting circuits.
It is a finite state machine (finite-state machine, FSM) that it is configurable, which to detect block 102, to detect simultaneously
The information of the running in the past of storage loads block 101, but it's not limited to that for embodiment of this case.That is, detecting block 102 is used
To reflect the input variation at the moment till now since system.Furthermore, detecting block 102 is defeated through receiving first
Enter to hold the first power supply V1 or receive accessory power supply VA to be driven that IT is inputted, uses the work shape of detecting load block 101
State.Whether detecting block 102 has voltage mistake through the detecting voltage unit 1021a detecting load blocks 101 of analogous circuit 1021
The error flag (error flag) of load block 101 occurs and records for low situation, or even further control or adjustment are outer
Portion power supply VO.On the other hand, the first low pressure difference linearity voltage regulation unit 1021b of analogous circuit 1021 is further converting first
Power supply V1 or accessory power supply VA is the second source V2 for driving digit circuit 1022 to receive.It is noted that in the first low pressure
In the case that the input voltage or output current of poor linear voltage stabilization unit 1021b changes, the first low pressure difference linearity voltage regulation unit
1021b is to maintain stable output voltage.In embodiment of this case, the first low pressure difference linearity voltage regulation unit 1021b is to use
To export second source V2 to digit circuit 1022, driving digit circuit 1022 is used.
In some embodiments, external power supply VO can be 3.3 volts and (such as switch to 3.3 volts by 12 volts of power supply on vehicle
It is special), the voltage of the first power supply V1 can be that 3.3 volts and second source V2 of voltage can be 1.2 volts.However, actually answering
In using also can according to user using required numerical value as embodiment, this case not with external power supply VO, the first power supply V1 with
And the voltage value of second source V2 is as limitation.
Now protects circuit 103 to receive external power supply VO and export accessory power supply VA.In other words, protection is flowed through
It is an accessory power supply VA that the external power supply VO of circuit 103 will be exported by protection circuit 103.In embodiment of this case, circuit is protected
103 are realized with diode, and the anode of diode is coupled to external input terminals ET, and the cathode of diode is coupled to analogous circuit

102 to maintain the running of detecting block 102.It is noted that protection circuit 103 is that can generate 0.3 to 0.8 volt of pressure drop
Diode so that accessory power supply VA and the first power supply V1 have a voltage difference, allow the higher voltage source of voltage preferentially to power,
And wherein a power supply it is unstable and when its voltage being made to be less than the voltage of another power supply, by another power supply person take over power supply to avoid
Allow two power supply power consumptions simultaneously.
As described above, the joint power supply module 10 that embodiment of this case is proposed can utilize different input powers to form connection
Construction for electricity is closed, to reduce the case where detecting block 102 is abnormal because of single input power shakiness.
Then, the application of joint power supply module 10 will be further illustrated.Referring to Fig. 2, Fig. 2 is the joint of embodiment of this case
The block diagram of power supply system.In embodiment of this case, the joint power supply module 10 of Fig. 2 powers module 10 substantially with combining for Fig. 1
Identical, difference is that the analogous circuit 1021 of the joint power supply module 10 of Fig. 2 further includes mode controlling unit 1021c.Therefore,
The difference will be subsequently directed to be described in detail.
Joint power supply system 1 includes joint power supply module 10 and voltage stabilizing module 11.Voltage stabilizing module 11 includes that main power source is defeated
Enter to hold MT and output end OT, is coupled to respectively with the first power supply V1 of output, wherein output end OT to receive main power source Vbat
The first input end IT of joint power supply module 10.Voltage stabilizing module 11 includes the second low pressure difference linearity voltage regulation unit 111, the second low pressure
Poor linear voltage stabilization unit 111 includes control switch 1111.
It more carefully says, voltage stabilizing module 11 through main power source input terminal MT to receive main power source Vbat, and by main electricity
Through exporting the first power supply V1 by output end OT after source Vbat conversions.In embodiment of this case, main power source Vbat is 12 volts of vehicle
Use power supply.Voltage stabilizing module 11 penetrates 111 power supply on vehicle of the second low pressure difference linearity voltage regulation unit and is converted to the first power supply V1, and will
First power supply V1 is via output end OT outputs to be supplied to joint power supply module 10.
It is worth noting that, in embodiment of this case, the analogous circuit 1021 of joint power supply module 10, which has more, to be coupled to
The mode controlling unit 1021c for controlling switch 1111, to output mode signal to voltage stabilizing module 11 so that voltage stabilizing module 11 is cut
Be changed to light-load mode (low power control mode) or heavily loaded pattern (high power control mode), with into
One step provides the electricity-saving function of joint power supply system 1.For example, it is explained for finite state machine with detecting block 102, when having
Limit state machine need to open all or a large amount of buffer is (such as by programmable logic controller, logic gate, flip-flop etc. element
Formed) when carrying out storing state parameter, mode controlling unit 1021c outputs are being switched to the mode signal of heavily loaded pattern to steady
Pressing mold group 11.On the contrary, when finite state machine carrys out storing state parameter without the use of whole buffers, mode controlling unit
1021c outputs are being switched to the mode signal of light-load mode to voltage stabilizing module 11.
It more carefully says, when the second low pressure difference linearity voltage regulation unit 111 in voltage stabilizing module 11 receives scheme control list
When first 1021c output is switched to the mode signal of light-load mode, through control switch 1111 by the second low pressure difference linearity voltage stabilizing list
The internal circuit part of member 111 is closed to reduce the power consumption of the second low pressure difference linearity voltage regulation unit 111, thereby reduces by first
The maximum output current upper limit of power supply V1.Or when the second low pressure difference linearity voltage regulation unit 111 in voltage stabilizing module 11 receives
When being switched to the mode signal of heavily loaded pattern to mode controlling unit 1021c output, through control switch 1111 by the second low pressure
The internal circuit of poor linear voltage stabilization unit 111 is fully open to increase the power consumption of the second low pressure difference linearity voltage regulation unit 111,
Thereby improve the maximum output current upper limit of the first power supply V1.
In other words, in the mode signal of mode controlling unit 1021c outputs for receiving analogous circuit 1021, second
Low pressure difference linearity voltage regulation unit 111 makes voltage stabilizing module 11 be switched to light-load mode through control switch 1111 has first to export
First power supply V1 of electric current or the heavily loaded pattern of switching are to export the first power supply V1 with the second electric current, wherein the second electric current is more than
First electric current.

The difference of embodiment be that the voltage stabilizing module 11 of Fig. 3 further includes third low pressure difference linearity voltage regulation unit 112, and third low pressure
Poor linear voltage stabilization unit 112 has control switch 1121.And in embodiment of this case, the second low pressure difference linearity voltage regulation unit 111
It is switched without control, third low pressure difference linearity voltage regulation unit 112 is coupled to the second low pressure difference linearity voltage regulation unit 111.When steady
Third low pressure difference linearity voltage regulation unit 112 in pressing mold group 11 receives mode controlling unit 1021c outputs and is switched to underloading mould
When the mode signal of formula, third low pressure difference linearity voltage regulation unit 112 is closed through control switch 1121, therefore voltage stabilizing module 11
Only it is the first power supply V1 of the first electric current by the output of the second low pressure difference linearity voltage regulation unit 111.Or when in voltage stabilizing module 11
Third low pressure difference linearity voltage regulation unit 112 receive the pattern letter that mode controlling unit 1021c output is switched to heavily loaded pattern
Number when, third low pressure difference linearity voltage regulation unit 112 is opened through control switch 1121, therefore voltage stabilizing module 11 while by third
It is the first power supply V1 of the second electric current that low pressure difference linearity voltage regulation unit 112, which assists the output of the second low pressure difference linearity voltage regulation unit 111,.
Similarly, the second electric current is more than the first electric current.
To sum up, embodiment of this case sends out mode signal with to steady through the demand of mode controlling unit 1021c runnings
Pressing mold group 11 carries out the switching of pattern, to reach whole the effect of combining 1 power saving of power supply system.Although it is noted that
Be in embodiment of this case using one or two low pressure difference linearity voltage regulation unit 112,113 as explanation, but this field tool usually know
The knowledgeable should be appreciated that second, third low pressure difference linearity voltage regulation unit 112,113 that can also be three or more is equipped with control switch
1121, in the inside of second, third low pressure difference linearity voltage regulation unit 112,113, are reached with realizing three or more current-modes
The power saving effect of different brackets.Therefore, this case is not opened with second, third low pressure difference linearity voltage regulation unit 112,113 or control
The number of pass 1121 is as limitation.
