Which is the circuit diagram for solenoid driver?
The complete circuit diagram for Solenoid driver circuit is shown in the image below. We will understand why it is designed so, once after taking a look at the complete circuit. As you can see the circuit is very simple and easy to build, hence we can test this using a small breadboard connection.
What kind of regulator is used for solenoid?
You can look at the datasheet of your MOSFET if you are designing the circuit for some other Solenoid application. A 7805 Linear Regulator IC is used to convert the 12V input supply to 5V, this voltage is then given to the Gate pin of the MOSFET when the switch is pressed though a 1K current limiting resistor.
How much current does a solenoid valve draw?
The solenoid draws a continuous current of 700mA when energised and a peak of nearly 1.2A so we have to consider these things while designing the driver circuit for this particular Solenoid valve. The complete circuit diagram for Solenoid driver circuit is shown in the image below.
How does a solenoid driver work on a bread board?
Finally a diode is added in anti-parallel direction to prevent the solenoid coil from discharging into the power circuit. Now that we have understood how the Driver circuit works lets test the circuit by building it on a bread board. I have used a 12V adapter for powers supply and my hardware setup looks something like this when completed.
