Motor driver L298 Circuit Schematic Diagram
The L298 is a dual H-Bridge motor driver integrated circuit designed for controlling the direction and speed of DC motors. Each H-Bridge consists of four switches that can be controlled to allow current to flow through the motor in either direction, thus enabling forward and reverse operation. The L298 can handle a supply voltage of up to 46V, making it suitable for various motor applications.
When utilizing the L298 in parallel mode, two separate L298 ICs are connected to share the load of the motors. This configuration effectively doubles the current capacity, allowing for the control of more powerful motors or motors that require higher current. It is essential to ensure that both L298 drivers are synchronized to prevent uneven current distribution, which could lead to overheating or damage.
The control logic for the L298 can be implemented using a microcontroller or a similar device, which sends control signals to the enable and input pins of the L298. The enable pins allow for speed control through pulse-width modulation (PWM), while the input pins determine the direction of the motor.
For applications where precise control is necessary, additional components such as diodes for flyback protection and capacitors for noise filtering may be included in the circuit design. Proper heat sinking is also recommended to dissipate heat generated by the L298 during operation, particularly when driving motors at higher currents.
In summary, the L298 H-Bridge DC motor driver is a versatile and robust solution for driving DC motors in various applications, providing flexibility in current handling and control options.IC H Bridge DC motor driver L298 has two H-Bridge circuit in it, so it can be used to download the drive two DC motors. H Bridge DC motor driver L298 each can deliver currents up to 2A. However, in use, the H Bridge DC motor driver L298 can be used in parallel, so the ability to deliver the H Bridge DC motor driver L298 flow into 4A.
The consequen ces of the installation of H Bridge L298 DC motor driver with the parallel mode, you need 2 pieces Bridge H L298 DC motor driver to control two DC motors using H bridge DC motor driver L298 in parallel mode. 🔗 External reference
