STMicroelectronics L293B Push-Pull Four Channel Driver

The L293B from STMicroelectronics is a robust, high-voltage, high-current quad driver designed to provide bidirectional drive currents of up to 1A at voltages ranging from 4.5V to 36V. It is specifically engineered to drive inductive loads such as relays, solenoids, DC and stepping motors, and other high-current/high-voltage loads in positive-supply applications.

Key Features:

• 600mA Output Current Capability per Channel: The L293B can deliver up to 600mA per channel, allowing it to drive a wide range of loads.
• 1.2A Peak Output Current (non repetitive) per Channel: For short duration, the device can handle up to 1.2A per channel, making it suitable for starting or stopping inductive loads that require higher initial currents.
• Enable facility: Output clamp diodes are included for inductive transient suppression, which is crucial for driving inductive loads and protecting the device from voltage spikes.
• Overtemperature Protection: The built-in thermal shutdown feature ensures that the device operates within safe temperature limits.

Applications:

The versatility of the L293B makes it an ideal choice for a wide range of applications, including:

• Control of DC and bipolar stepping motors
• Position and velocity servomechanisms
• Automated industrial machines
• Robotics and automation systems
• Home appliances

Product Advantages:

The L293B driver integrates two full H-bridges, making it possible to control two DC motors independently in both clockwise and counterclockwise directions. Its design simplifies circuit complexity and allows for the creation of compact motor control solutions. The device's high voltage and current capabilities, coupled with protection features, make it a reliable choice for designers looking to implement robust motor control systems.
