The L293N is a quadruple half-H driver, meaning it contains four individual drivers that can be used independently or combined. Each driver can control a load of up to 600mA at voltages between 4.5V and 36V. This makes it suitable for a wide range of small to medium-sized motors. The datasheet provides specific details on how to configure these drivers for different motor control applications, such as controlling the direction and speed of a DC motor or stepping a stepper motor. The datasheet also shows ways to connect this IC with other components.
Moreover, the L293N datasheet typically includes example application circuits. These circuits illustrate how to connect the L293N to various components, such as microcontrollers, motors, and power supplies. These example circuits can be invaluable for getting started with motor control projects and providing a solid foundation for more complex designs. These designs should be implemented in an order like this:
- Choose the right power supply based on the motor’s voltage requirements.
- Connect the motor to the appropriate output pins of the L293N.
- Connect the L293N to a microcontroller or other control circuit.
