Key Features
- Dual H-Bridge Design: Drive two DC motors independently in both forward and reverse directions, or control one bipolar stepper motor with a single IC.
- Built-in Flyback Diodes: The "D" in L293D stands for the integrated clamping diodes that protect the IC from back-EMF voltage spikes generated by motors - no need for external diodes.
- PWM Speed Control Ready: Connect the Enable pins (EN1,2 and EN3,4) to PWM outputs on your microcontroller for smooth, variable speed control of each motor channel.
- Wide Motor Voltage Range: Separate logic and motor supply pins allow you to power motors from 4.5V up to 36V while keeping logic at a safe 5V level.
- 600mA Continuous Output: Each channel delivers up to 600mA continuously with 1.2A peak capability - ideal for small to medium DC motors, gear motors, and hobby servos.
- TTL & CMOS Compatible: Works directly with 5V logic from Arduino, ESP32, STM32, PIC, Raspberry Pi GPIO, and virtually any microcontroller without level shifting.
- Thermal Shutdown Protection: Internal thermal protection circuit automatically shuts down the IC if it overheats, preventing permanent damage.
- Breadboard Friendly: Standard 16-pin DIP package fits directly into breadboards, perfboards, and standard IC sockets for easy prototyping and replacement.
