The L293D from STMicroelectronics is a monolithic integrated high voltage, high current four-channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive-supply applications.

Key Features

• 600mA Output Current Capability per Channel: The L293D can deliver up to 600mA per channel, allowing it to drive a wide range of motors and other inductive loads effectively.
• 1A Peak Output Current (non repetitive) per Channel: It provides a peak current of 1A for a brief period, which is helpful for startup or sudden load changes.
• Enable facility: Output clamp diodes are included for inductive transient suppression while the enable function allows the user to turn off the output without disrupting the input signal.
• Overtemperature Protection: The built-in overtemperature protection ensures that the IC does not overheat, thereby preserving the integrity of the motor driver.

Applications

The versatility of the L293D makes it suitable for a wide array of applications, including:

• Stepper motor drivers
• DC motor drivers
• Robotics and automation systems
• Position and velocity servomechanisms
• Actuator drives

Technical Specifications

The L293D is characterized by several technical specifications that make it a robust choice for driving motors:
