L293D Motor Driver controls the speed and direction of two DC motors or
a single stepper motor. Widely used in robotics and automation projects, it
provides reliable performance with easy integration into microcontroller-based
systems.
Description:
The L293D DC Motor Driver is a
dual H-Bridge motor driver IC that allows control of two DC motors in both
forward and reverse directions. It is widely used in robotics, automation, and
embedded systems for motor control. With built-in current protection and separate
power supply pins for logic and motors, it ensures efficient motor operation.
The L293D can handle small to medium-sized DC motors with up to 600ma continuous
current per channel.
Specifications:
Operating Voltage: 4.5V – 36V DC
Logic Voltage: 4.5V – 5V
Continuous Output Current: 600ma per channel
Peak Output Current: 1.2A per channel (short
duration)
Motor Channels: Dual H-Bridge (can drive 2 DC
motors or 1 stepper motor)
PWM Control: Supports speed control via Pulse
Width Modulation (PWM)
Thermal Protection: Built-in internal diodes for
protection
Size: Compact 16-pin DIP package
Features:
Drives two DC motors independently or one stepper
motor
Bidirectional control for motor forward and
reverse operation
Separate power supply pins for motor and logic
sections
PWM support for speed control
Built-in flyback diodes to protect against
voltage spikes
Compatible with Arduino, Raspberry Pi, and other
microcontrollers
Applications:
Robotics: Motor control for robotic arms,
vehicles, and automation systems
DIY Electronics: Used in hobbyist projects for
motion control
CNC Machines: Controls stepper motors for precise
movements
