| The 2 channel DC motor driver circuit on a saving model Posted: 21 Jan 2013 03:16 AM PST This circuit has 2 input and if both it’s input is "1" (+12 volt) What will happen?, If some input voltage is "0" (such as input A) transistor T5 will conduct a current and as cause to transistors T1 and T4 also conducts, and makes the DC motor running In one direction. When it comes this time, we will explain what is part of this circuit that saving. -You will notice that.Each pair of transistors in bridge is controlled by only one transistor driver. This thing not only saves equipment. It also saves energy. Which is opposite to the two transistor driver. When the transistor T5(BD140 or BD136) conduct the T1(BD242) work with, the current flow of T1 by controller of T5 go to base of T4 cause T4(BD241) also conduct. This means that we use the base current of T1 and T3(BD242). In driving the T4 and T2(BD241), respectively, [...]  |
