Description
Technical field
The present invention relates to a kind of New-type electric machine drive circuit.
Background technology
Existing drive circuit is varied of a great variety, but most complex structure, function is complicated; And only need under the application scenario of function singleness at some, adopt the drive circuit of complicated circuit construction to accomplish the motor-driven function of simple function often, cost can increase so on the one hand; The voltage narrow application range, in addition on the one hand, after circuit structure is in a single day complicated; Its destabilizing factor is behind so just reducing product percent of pass virtually also increasing.Q4 in the prior art, that Q7 adopts is PNP, the PNP conducting resistance is big, a little less than the driving force, need take bigger area, thereby cost is high.
Summary of the invention
The object of the present invention is to provide a kind of novel motor-drive circuit, to solve the problem that there is the voltage narrow application range in prior art, cost is high and reduce product percent of pass.
Reaching the technical scheme that the object of the invention takes is: a kind of novel motor-drive circuit; It is characterized in that: comprise first triode, second triode, the 3rd triode, the 4th triode, the 5th triode, the 6th triode, the 7th triode, the 8th triode; The first input end mouth is connected with the ground level of the 3rd triode and is connected with second triode through resistance R 1; Second input port is connected with the ground level of the 5th triode and is connected with the 6th triode through resistance R 2; The emitter of the 3rd triode is connected with the base stage of first triode; The collector electrode of the 3rd triode is connected with the collector electrode of first triode and is connected to jointly on the power vd D; The emitter of the 5th triode is connected with the base stage of the 7th triode; The collector electrode of the 5th triode is connected with the collector electrode of the 7th triode and is connected to jointly on the power vd D, and the emitter of second triode is connected with the base stage of the 8th triode, and the collector electrode of second triode is connected with the collector electrode of the 8th triode and is connected to jointly on second output port with the emitter of the 7th triode; The collector electrode of the 6th triode is connected with the collector electrode of the 4th triode and is connected on first output port emitter common ground of the emitter of the 4th triode and the 8th triode jointly with the emitter of first triode.
The beneficial effect that the present invention reaches is: adopt the present invention to reach the circuit level height, use simple, voltage beneficial effect applied widely and with low cost.
