Key Features

Dual H-Bridge Configuration
The L293D features a dual H-Bridge configuration, allowing you to control two DC motors independently. This enables precise motor control in both forward and reverse directions, making it perfect for robotics and automation projects.

PWM Control for Speed Adjustment
With support for PWM (Pulse Width Modulation) control, the L293D offers the ability to adjust motor speed by varying the duty cycle of the PWM signal. This provides precise control over motor performance, essential for applications requiring variable speed.

Moderate Current Handling
The L293D is capable of driving up to 600mA of continuous current per channel, with peak currents up to 1.2A. This makes it suitable for controlling small to medium-sized DC motors commonly used in robotics, remote-controlled vehicles, and similar applications.

Built-In Back EMF Protection
To protect your circuit components, the L293D includes built-in diodes for back EMF protection. This ensures the safety of your circuit when the motor suddenly stops or changes direction.

Ease of Use

Wide Voltage Range
The L293D operates on a wide voltage range of 4.5V to 36V, making it compatible with a variety of power sources. This flexibility allows it to be used in diverse projects and applications.

Thermal Shutdown Protection
Designed with thermal shutdown protection, the L293D prevents overheating during extended operation, ensuring long-term reliability and safety.

Compact Design
Housed in a compact DIP16 package, the L293D is easy to integrate into your circuit design, whether on a breadboard, PCB, or custom board.

Conclusion

Whether you’re building a simple motorized project or a complex automation system, the Motor Driver L293D is an indispensable tool for achieving precise and reliable motor control. Its robust design, ease of use, and flexibility make it a popular choice among hobbyists, engineers, and professionals alike.
