The L293D is a popular dual H-bridge motor driver integrated circuit (IC) manufactured by Texas Instruments. It is designed to control two DC motors or a single stepper motor, making it well-suited for use in robotics, automation, and other motion control applications. The L293D features two H-bridge drive circuits, which allow it to drive the motor in both directions (clockwise and counterclockwise) with easy control from a microcontroller or other digital circuit. The L293D also includes built-in protection diodes for back electromotive force (EMF) and is capable of driving motors with a voltage range of 4.5V to 36V, with a peak output current of 600mA per channel and a continuous current of 600mA per channel. This makes it suitable for a wide range of motor control applications. The IC is also available in a variety of package types, making it adaptable to different design requirements. With its high reliability and capability, the L293D is a popular choice for hobbyists, students, and professionals working on motor control projects.
