How to use the L298N Dual H-Bridge Motor Driver
- Attach your robot’s motors to the green Motor A and Motor B screw terminals.
- Connect the ENA and ENB to PWM capable digital outputs on your robot’s microcontroller.
- Connect the IN1, 2, 3 and 4 pins to any digital outputs your robot’s microcontroller.
What is H-Bridge module?
An H-bridge module is equipped with four IGBTs and four free-wheeling diodes, which usually have 600 V, 1200 V or 1700 V blocking voltage. The IGBTs and diodes often share the same current rating. MOSFETs with 600 V are also frequently used in H-bridges as SiC components are used more and more.
What is better than L298N?
As a conclusion, TB6612FNG and LV8406T are better than L298N in efficiency test. 2). Security, Operating Voltage, Operating Current, Heat Performance and the Volume of the Module.
How does H-Bridge motor driver work?
A motor driver interprets the control signals and amplifies them to control the FETs found in the H-bridge. The FETs are turned on or off depending on the polarity of the control signal the FETs are connected to. By controlling when and what FETs are turned on or off, a flow of current to the motor can be controlled.
What is H-Bridge motor driver?
A H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.
Can we connect 4 motors to L298N?
The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. So the answer is no, it won’t allow the independent control of four motors, but you could possibly connect two in parallel to each output, depending upon the application.
Why do we need H-Bridge?
The H-bridge arrangement is generally used to reverse the polarity/direction of the motor, but can also be used to ‘brake’ the motor, where the motor comes to a sudden stop, as the motor’s terminals are shorted.
What is the purpose of an H-Bridge?
The H-bridge is an electronic circuit that looks like the letter H. An H-bridge is used to drive a load, such as a brushed DC motor, in both directions. And it controls the flow of current to a load.
Which is better L293D or L298N?
L293D Drivers Operates at 4.5V to 36V whereas L298N can be Operates at up to 46V. Maximum 600mA Current can be drawn through both channels of L293D whereas L298N Motor Driver can draw up to 2A from both channels.
Can I use L293D instead of L298N?
No. Drive voltage or the external voltage required to run the DC motor can be anywhere between 4.5V to 36V for L293D whereas between 5V to 46V for L298N. The maximum output current through one channel of L293D is 600mA whereas L298N Motor Driver can give up to 2A from both channels.
Why we use H bridge?
What is the purpose of H bridge?
Why do we need H-bridge for DC motor?
* Provide the ability to reverse current across a DC motor, allowing for rotation in either direction. Additionally, H-Bridges allow loads to be powered independently from the control signals that are controlling them, providing circuit isolation.
Why do we need H-bridge?
Can I power L298N with Arduino?
It can control motors which operates between 5 to 35V and up to 2A. The module has an onboard regulator which helps in giving the output of 5V. The module can be powered from 5 to 35V from Arduino or external power supply. It is recommended to always use the external voltage supply.
How many DC motors can an Arduino control?
The L298 can control the speed and direction of DC motors and stepper motors and can control two motors simultaneously. Its current rating is 2A for each motor.
Why are H bridges used for DC motors?
DC motor Driver
The H-bridge arrangement is generally used to reverse the polarity/direction of the motor, but can also be used to ‘brake’ the motor, where the motor comes to a sudden stop, as the motor’s terminals are shorted.
How does H bridge works?
An H-bridge is built of four switches that control the flow of current to a load. In the image above, the load is the M connecting the two sets of switches. Using one current source, you can drive current in two directions by closing two switches.
Why do we need H bridge for DC motor?
Can I use L298N instead of L293D?
L293D is a quadruple motor driver that employs a half-H driver, whereas L298N is a dual full-H driver, which means that in L293D all four input-output lines are independent, whereas in L298N a half-H driver cannot be utilized separately, and only a full H driver may be used.
How does H bridge control motor speed?
To control the speed of the motor you apply a Pulse Width Modulation (PWM) signal to the Enable line. The shorter the pulse width, the slower the motor will spin.
How does H-Bridge control speed of DC motor?
H bridge curcuit is used for controlling DC motor speed and rotating side. The H bridge driver Mosfets are driven by a high frequency PWM signal. Controlling the PWM duty cycle is equivalent to controlling the motor terminal voltage, which in turn adjust directly the motor speed.
How do I know if my L298N is working?

Can I connect DC motor directly to battery?
Can I connect a DC motor directly to a battery? Yes, it will be much happier than if you plug it into a wall socket. The wall socket is mist likely AC & all batteries are DC. If the motor & battery are rated for the same voltage & the battery has enough capacity to supply the motor load, There’s no problem.
