The L293D is a monolithic integrated, high-voltage, high-current, 4-channel driver.Essentially, it is a Dual H-Bridge motor driver that can drive inductive loads like relays, solenoids, DC motors, and bipolar stepping motors.It allows your low-power microcontroller (like Arduino or ESP32) to control high-power motors safely without the risk of burning out your controller’s pins.
Key Features
Dual Motor Control: Independently control the speed and direction of two DC motors or one 4-wire stepper motor.
Internal Protection: Built-in “kickback” diodes protect your circuit from back EMF (voltage spikes) produced by the motors.
Compact DIP-16 Package: Breadboard-friendly design makes it ideal for prototyping and student labs.
Thermal Shutdown: Features internal overheating protection to prevent the chip from burning out under high loads.
Wide Voltage Range: Supports motor voltages from 4.5V up to 36V.
