When the button is not pressed the transistor will be in open state and the Motor receives 12V from the drain of the FET Q1 on its positive pin. When both source are connected to ground or negative terminal of the battery we will have the output for our DC motor in Q1’s drain pin and Q2’s source.Ĭonnecting a button between the battery and each of the gates of FET can be used to control the ON/OFF state of transistor. Source pin of both the MOSFET’s are connected to ground or negative terminal of the battery. ![]() A Switch Sw1 connects it directly to the Gate of both the MOSFET. If you are looking for motor driver circuit to be used with Microcontroller or Development boards consider this Bidirectional motor control circuit for ease of use and have more control over the motor movements.įirst we have our source of energy a 12VDC Battery. In fact it takes only very few components and can be built pretty easily. This circuit can be used as a Motor driver in different projects. In this circuit the DC motor keep on running in one direction until when the switch is pressed it reverses its direction. ![]() ![]() This is a DC motor driver circuit using a single N channel MOSFET.
