Description
Technical field
The utility model 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 needs under the application scenario of function singleness at some, adopts often the drive circuit of complicated circuit construction to finish the motor-driven function of simple function, 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 large, a little less than the driving force, need take larger area, thereby cost is high.
Summary of the invention
The purpose of this utility model 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.
