A simple motor driver circuit using IC TC4424 chip is really important for controlling DC motors effectively.
The TC4424 is designed to drive two MOSFETs and works great for fast applications, making it perfect for motor control with just a few extra parts needed.
This circuit is easy to set up and lets you run a DC motor while also controlling which way it spins.
You can power this circuit with a voltage between 10 and 18 volts DC depending on what your motor needs.
Just remember the motor should not use more than 100 milliamperes of current.

The TC4424 is a special chip that works as a dual high speed driver for MOSFETs, which helps control a direct current DC motor really well.
This chip uses a control signal to decide which way the motor should spin.
To keep everything working smoothly the control inputs called POWER and DIRECTION are connected with pull down resistors R1, R2.
These resistors help keep the circuit stable.
When the direction control is set to HIGH, the chip changes the motors polarity making it spin in one direction.
If the direction control is set to LOW the polarity flips and the motor spins the other way.
The circuit also has diodes D1, D2, D3, D4 that act as freewheeling diodes.
They protect the circuit from back electromotive force EMF that the motor creates while it runs.
Plus, there are capacitors C1, C2 included to filter out noise and help the chip work steadily.
This circuit can run well with a voltage between 10V and 18V DC making it a great option for different DC motor uses.
