The L293D is a popular motor driver IC (integrated circuit) designed to drive inductive loads such as DC motors and stepper motors. It provides bidirectional control of two motors, making it suitable for a variety of motor control applications. The L293D is widely used in robotics, mechatronics, and other projects where motor control is required. Here are some key features and specifications of the L293D motor driver:
Dual H-Bridge Configuration: The L293D features two H-bridges, allowing it to control the direction of rotation and speed of two DC motors independently.
Motor Voltage: It is designed to work with a wide range of motor voltages, typically up to 36V, making it suitable for various motor types and applications.
Current Rating: The L293D can handle a continuous output current of up to 600mA per channel and a peak output current of up to 1.2A per channel. It is important to note that the actual current handling capability may vary depending on the specific model and operating conditions.
Built-in Diodes: The IC includes built-in diodes (flyback diodes) that provide protection against voltage spikes generated by inductive loads, such as motors.
Logic Compatibility: The L293D is compatible with TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic levels, making it easy to interface with microcontrollers and other digital control systems.
Enable Inputs: Each H-bridge has an enable input (EN) that allows you to selectively enable or disable the corresponding motor.
Package: The L293D is commonly available in a 16-pin DIP (Dual In-line Package) or a surface-mount package.
Applications: The L293D is widely used in applications such as robot motor control, electronic toys, CNC machines, and other projects where precise control of DC motors is required.
