Disturb.Tenth resistance R10 is current-limiting resistance, and the tenth resistance R10 is used to carry out the branch road where the 3rd triode Q3 colelctor electrode
Overcurrent protection, therefore the safety and reliability of circuit is higher.
It is noted that in the present embodiment, the first triode Q1, the second triode Q2 and the 4th triode Q4 are
PNP type triode, the 3rd triode Q3 is NPN type triode.Certainly, under the certain situation of the present embodiment, the first triode
Q1, the second triode Q2 and the 4th triode Q4 can also be NPN type triode, and the 3rd triode Q3 is PNP type triode,
But at this moment the structure of circuit also will accordingly change.
Voltage input end VIN inputs 3V DC voltages, due to the first triode Q1, the second triode Q2 and the 4th triode
Q4 pipe collector junction and emitter junction is all reverse-biased, and the first triode Q1, the second triode Q2 and the 4th triode Q4 are in cut-off shape
State, base current is zero, because base stage does not have an electric current, therefore colelctor electrode also no current, causes the load for being connected to collector terminal
Also without electric current, and equivalent to switching on.
When user presses touch-switch K moment, there is 0.64V conducting voltage the 3rd triode Q3 base stage moment, makes
3rd triode Q3 is turned on, and due to there is base current flowing, therefore colelctor electrode is flowed through bigger amplification electric current, therefore load back
Road is just switched on, and makes have electric current to flow through on the 4th resistance R4 and the 5th resistance R5, and on the 4th resistance R4 and the 5th resistance R5
Pressure drop is produced, so that the first triode Q1 and the second triode Q2 base voltage are less than emitter voltage, the 4th resistance R4
Moderate resistance is taken with regard to the first triode Q1 and the second triode Q2 base voltage can be made to reach enough high standard with the 5th resistance R5
Position, to drive the first triode Q1 and the second triode Q2 to be worked into saturation workspace.First triode Q1 and the two or three pole
When pipe Q2 is in saturation state, the electric current of colelctor electrode is quite big.
Because the first triode Q1 colelctor electrode and the 4th triode Q4 emitter stage are joined directly together, the first triode Q1's
Collector current is also the 4th triode Q4 emitter current, so that the 4th triode Q4 colelctor electrode also has electric current stream
Cross, and pass through second resistance R2 and 3rd resistor R3 partial pressures, for the 3rd triode Q3 base stage provides stably close to critical
The voltage (Vb=0.64V) of value, so as to ensure that being operated in for the first triode Q1, the second triode Q2 and the 4th triode Q4 is full
And state.First triode Q1, the second triode Q2 and the 4th triode Q4 base stage have electric current, because base stage has electric current, because
This colelctor electrode also has high current, causes the load for being connected to collector terminal also to have electric current, and equivalent to the closure of switch.Its VCE
Level off to zero.Voltage input end VIN voltage is by the second triode Q2 colelctor electrode from voltage output end VOUT output voltages.
When user needs to close power supply, then put click touch-switch K just can deenergization immediately.Due to the first electricity
Hold C1 presence, when the moment for pressing touch-switch K, the voltage (Vb=of the 3rd triode Q3 base stage close to critical value
0.64V), connected by touch-switch K moment and the first electric capacity C1 is charged, so that the 3rd triode Q3 base stage
Voltage (Vb=0.64V) close to critical value is less than 0.64V, causes the 3rd triode Q3 to be changed into ending shape from conducting state
State.So as to also make the first triode Q1, the second triode Q2 and the 4th triode Q4 be changed into cut-off state from saturation state.Three poles
The base current of pipe is zero, because base stage does not have an electric current, therefore colelctor electrode also no current, causes the load for being connected to collector terminal
Also without electric current, and equivalent to switching on.Therefore the second triode Q2 colelctor electrode is without output voltage.When reopening power supply
When, only it need to press touch-switch K.Such as need to close power supply, only need to press touch-switch K again.And so on, power-on/pass
Closing power supply function, also order is realized.
