The L293D Quadruple Half-H Bridge Motor Driver IC is the industry-standard choice for controlling small DC motors and stepper motors. At Electrapac, we recommend this "all-in-one" driver for hobbyists building their first remote-controlled cars, automated curtains, or small robotics platforms.
The L293D is designed to provide high-current bidirectional drive signals to motors at voltages up to 36V. While a microcontroller like an Arduino can provide the logic, it cannot provide the raw power (current) a motor needs; the L293D acts as the high-power bridge between the two. Crucially, the "D" version includes internal clamp diodes, which protect your sensitive electronics from the "back-EMF" voltage spikes generated by spinning motors.
Bidirectional Control: Easily change the direction of your motors (Forward/Reverse) by toggling the input logic pins.
Speed Control (PWM): By connecting the "Enable" pins to a PWM-capable pin on your microcontroller, you can vary the speed of your motors from 0% to 100%.
Independent Power Supplies: The IC separates logic power (5V) from motor power (up to 36V), ensuring that motor noise doesn't interfere with your controller's stability.
Breadboard Ready: The 16-pin DIP format is perfect for prototyping on standard breadboards available at
Space Efficient: One single chip can handle two DC motors, saving significant space compared to using discrete transistors.
2WD/4WD Robots: The classic "brain" for differential drive hobby robots.
Stepper Motor Control: Driving 4-wire bipolar stepper motors for precise positioning.
Solenoid Actuators: Controlling high-voltage solenoids or relays.
Smart Home Automation: Opening and closing motorized blinds or locks.
Educational Science Projects: Learning the fundamentals of H-Bridge circuits and pulse-width modulation.
We source the L293D with high-quality lead frames to ensure better heat dissipation during heavy loads. At
