With between circuit output cathode BAT+, one end of resistance R1 is connected with the grid of the first metal-oxide-semiconductor Q1, and the other end is as protected location
The first control end of 10, one end of resistance R2 is connected with the grid of the second metal-oxide-semiconductor Q2, and the other end is as the second of protected location 10
Control end.Switch element 20 is connected between circuit input positive pole CHR+ and circuit input negative pole CHR-, and outfan is single with protection
First control end of unit 10 connects, and controls the break-make of the first metal-oxide-semiconductor Q1.The first input input first starting control unit 30
Enabling signal EN1, outfan is connected with the input of switch element 20, controls the break-make of switch element 20.Second starts control
Input input the second enable signal EN2 of unit 40, outfan is connected with the second control end of protected location 10, controls second
The break-make of metal-oxide-semiconductor Q2.
The present embodiment by by two metal-oxide-semiconductor Opposite direction connections, the forward voltage drop that when reducing charging, circuit produces, thus carry
High battery charge also reduces system power dissipation.
The following detailed description of the controlled battery charger according to the present invention.
First input input the first enable signal EN1 starting control unit 30, controls the break-make of switch element 20, from
And control the break-make of the first metal-oxide-semiconductor Q1；And the second input input second starting control unit 40 enables signal EN2, with control
Make the break-make of the second metal-oxide-semiconductor Q2.When charging, the first metal-oxide-semiconductor Q1 and the second metal-oxide-semiconductor Q2 turns on, and therefore electric current can pass through
Battery is charged by protected location 10.Owing to internal resistance when metal-oxide-semiconductor turns on is the least, the pressure therefore produced on two metal-oxide-semiconductors
Fall is far smaller than pressure drop produced by counnter attack diode in prior art, greatly reduces the power consumption of system, and improves electricity
Pond charge capacity.
Alternatively, the first enable signal EN1 and the second enable signal EN2 can be given by internal single-chip microcomputer.This area skill
Art personnel should be appreciated that the first enable signal EN1 and second enables signal EN2 and can provide in any suitable way.
When leaving charging device according to the controlled battery charger of the present invention, enable signal EN2 by the by second
Two metal-oxide-semiconductor Q2 control as turning off.When circuit input positive pole CHR+ and circuit input negative pole CHR-short circuit, due to the second metal-oxide-semiconductor
Q2 turns off, and the electric current that its parasitic diode flows out relative to circuit output cathode BAT+ is Opposite direction connection, therefore electric current
Cannot circulate so that battery short circuit electric discharge phenomena will not occur during input port short circuit.
If first enables signal EN1, the first metal-oxide-semiconductor is controlled as turning off, even if charging circuit is on charging device, also
Battery can not be charged.

R10 is connected in parallel between circuit output cathode BAT+ and the second control end of protected location 10.
Owing to the internal cell system of charging device Yu operation has voltage difference, and charging device inside exports to have and is electrolysed greatly electricity
Holding, also have electrochemical capacitor and battery system internal resistance the least in battery charger input, therefore charging device connects battery and fills
Transient Currents can be produced during electricity circuit, and cause spark phenomenon.
Controlled charging battery circuit according to an embodiment of the invention, in the moment that input port is electrically charged, three poles
Pipe Q3 turns on.Owing to electric capacity both end voltage can not be suddenlyd change, the equal i.e. electric capacity C1 two of the gate-source voltage of the first metal-oxide-semiconductor Q1 under transient state
The voltage of end is zero, but owing to the conducting of audion Q3 makes electric capacity C1 be charged by R3, and it is discharged by resistance R9, therefore electricity
The voltage holding C1 two ends slowly rises by zero, is finally reached resistance R9 and the resistance R3 partial pressure value to charging voltage.Due to
The gate-source voltage of the first metal-oxide-semiconductor the most slowly increases so that the first metal-oxide-semiconductor Q1 works, during low pressure under linear condition
Its conducting resistance is relatively big, thus plays the effect of transient suppression electric current.Thus controllable aerating according to an embodiment of the invention
Electricity battery circuit it can be avoided that connect the moment generation spark phenomenon of this circuit at charging device.
Alternatively, switch element 20 can include audion Q3 and resistance R3, R4, R5.As in figure 2 it is shown, resistance R4 and R5
Being connected in series between circuit input positive pole CHR+ and circuit input negative pole CHR-, the junction point of resistance R4 and R5 is switch element
The input of 20, the base stage of audion Q3 is connected with the input of switch element 20 and one end of colelctor electrode and resistance R3 connects
Connecing, the other end of resistance R3 is the outfan of switch element 20, and audion Q3 controls the break-make of the first metal-oxide-semiconductor Q1.
In the case of battery does not has electricity completely, there is no control signal inside battery charger, but be connected to fill at circuit
During electric installation, the dividing potential drop between resistance R4 and R5 makes Q3 turn on, therefore the first metal-oxide-semiconductor conducting, and due to the second metal-oxide-semiconductor Q2
With Q1 Opposite direction connection, therefore the parasitic diode of the second metal-oxide-semiconductor Q2 directly turns on, so electric current still can flow through protected location
10 pairs of batteries are charged.Therefore, the controlled charging battery circuit of this embodiment can also work when battery does not has electricity completely, right
Battery is charged.
Alternatively, the first startup control unit 30 can include audion Q4 and resistance R6.As in figure 2 it is shown, resistance R6 is also
Connection is connected between base stage and the emitter stage of audion Q4, and the base stage of audion Q4 is the input of the first startup control unit 30
End, input the first enable signal EN1, current collection extremely first starts the outfan of control unit 30, with the input of switch element 20
End connects.First enables signal EN1 controls the break-make of audion Q4, thus controls the break-make of switch element 20.
Alternatively, the second startup control unit 40 can include audion Q5 and resistance R7, R8.As in figure 2 it is shown, resistance R8
Being connected in parallel between base stage and the emitter stage of audion Q5, the base stage of audion Q5 is the input of the second startup control unit 40
End, input the second enable signal EN2, colelctor electrode is connected with one end of resistance R7, and the other end of resistance R7 is that the second startup controls
The outfan of unit 40, is connected with the second control end of described protection circuit, and second enables signal EN2 controls the second metal-oxide-semiconductor Q2
Break-make.
When the first enable signal EN1 is low level, first starts the audion Q4 cut-off in control unit 30, therefore opens
The input voltage closing unit 20 is the dividing potential drop that resistance R4, R5 produce, and it makes audion Q3 turn on, therefore in protected location 10
First metal-oxide-semiconductor Q1 conducting.I.e. the charge initiation control signal of this rechargeable battery circuit be the first enable signal EN1 be low level.
When the first enable signal EN2 is high level, first starts the audion Q4 conducting in control unit 30, therefore switch element 20
