Metal-oxide-semiconductor U1, U2, U3, U4 can regulate the output different voltages with different; Example metal-oxide-semiconductor U1, when the G pin high-low level duration not simultaneously, metal-oxide-semiconductor U1 conducting and the time that ends also can change; If the G pin high-low level duration of control metal-oxide-semiconductor U1 and metal-oxide-semiconductor U4; The time that just can control the motor conducting and end, rotating speed just has difference, so just can control rotating speed of motor.
But metal-oxide-semiconductor has individual characteristic; The voltage of G pin is greater than about S pin voltage 3V; Like this, the G pin of metal-oxide-semiconductor U3, metal-oxide-semiconductor U4 just must have the voltage greater than positive source, so metal-oxide-semiconductor U3 and metal-oxide-semiconductor U4 need a chip for driving to produce a high voltage.
In sum, conventional method can accomplish to control simultaneously motor positive and inverse and motor speed, but needs four road metal-oxide-semiconductors, but also will increase chip for driving, and therefore such control method just needs very high cost.
