L293D Motor Driver IC
Motor Driver IC: The L293D is primarily designed as a motor driver IC. It is specifically used for controlling the direction and speed of DC motors and stepper motors.
H-Bridge Configuration: It features two H-bridge circuits, which allow it to control two DC motors independently or one bipolar stepper motor. An H-bridge is a configuration that enables bidirectional control of motors.
Voltage and Current Ratings: The L293D IC can typically handle a wide range of motor supply voltages, commonly from 4.5V to 36V. It can also handle motor currents up to 600mA per channel (1.2A peak). These voltage and current ratings make it suitable for various motor applications.
Logic Inputs: The IC accepts logic-level inputs (high and low) to control the direction and speed of the motors. It provides separate input pins for each motor to control forward, reverse, and braking operations.
Built-in Diodes: The L293D includes built-in flyback (freewheeling) diodes. These diodes protect against voltage spikes generated when the motor is turned off, ensuring safe operation.
Package Types: The L293D is available in various package types, including the 16-pin DIP (Dual Inline Package) and the 16-pin SOIC (Small Outline Integrated Circuit).
Applications: The L293D is commonly used in robotics, remote-controlled vehicles, automation projects, and other applications where motor control is required.
