The Motor Driver Circuit using IC TC4424 chip works well for DC motor control because it drives two MOSFETs, operates fast, and needs only a few extra parts.
In addition , circuit is easy to build and can control motor spin direction, also it power 10 to 18V DC which depends on motor; further more motor current must be under 100mA.
Circuit Working:
Parts List:

To begin with, TC4424 chip IC is fast dual driver for MOSFET and is good for DC motor control and control signal chooses motor spin way.
Further, POWER and DIRECTION inputs have pull-down resistors R1 and R2 for stable work.
Then direction HIGH motor spin one way and direction LOW motor spin other way.
After that, diodes D1 to D4 stop back EMF from motor and capacitors C1 and C2 cut noise and keep chip steady.
As a result, circuit works with 10 to 18V DC and is good for many DC motor jobs.
How to Build:
To build a Motor Driver Circuit using IC TC4424 follow the below mentioned steps:
- First, assemble parts from circuit diagram.
- Next, pin 2 of TC4424 IC goes to POWER input.
- Then pin 3 goes to GND.
- After that, pin 4 goes to DIRECTION input.
- Now pin 5 connects to one motor terminal and pin 7 goes to other motor terminal.
- Further, pin 6 connects to 10 to 18V DC supply.
- Also, R1 connects to one end +5V and other end goes to pin 2 and R2 connect to one end of +5V and other end goes to pin 4.
- Next, C1 and C2 connect between 10 to 18V DC and GND.
- Then D1connect anode GND, and cathode pin 5 and D2 connect anode pin 5 and cathode of 10 to18V DC.
- Finally, D4 connect anode GND and cathode to pin 7 and then D3 connect anode pin 7 and cathode to 10 to 18V DC.
Conclusion:
To conclude, Motor Driver Circuit using IC TC4424 is easy, fast and controls direction, also the circuit just needs few parts to make.
In addition, Schottky diodes stop back EMF and make circuit strong for many uses.
