L293D Driver IC

L293D Motor Driver IC Overview

• Functionality: Dual H-Bridge motor driver IC, capable of driving two DC motors or one stepper motor.
• Motor Compatibility:
  • DC Motors: Can control up to two DC motors bidirectionally.
  • Stepper Motors: Can drive a single stepper motor (4-wire, 5-wire, or 6-wire configuration).
• Power Handling:
  • Voltage Range: Typically operates from 4.5V to 36V.
  • Current Handling: Can handle continuous current up to 600mA per channel (1.2A peak per channel).
• Control Interfaces:
  • Logic Control: Requires two logic inputs per motor (one for direction and one for enable).
  • Built-in Diodes: Includes built-in diodes (flyback diodes) for protection against back EMF generated by the motors.
• Features:
  • PWM Control: Allows for speed control of DC motors using Pulse Width Modulation (PWM).
  • Direction Control: Supports bi-directional control of motors (forward, reverse, brake, and stop).
  • Thermal Shutdown: Incorporates thermal shutdown protection to prevent damage from overheating.
• Applications:
  • Robotics: Used in robot platforms for motor control.
  • RC Vehicles: Controls motors in remote-controlled vehicles.
  • Automation: Implements motor control in various automated systems.
  • DIY Projects: Popular in hobbyist projects for motor control.
