L293D Motor Driver IC

The L293D Motor Driver IC is a quadruple high-current half-H driver chip that provides bidirectional drive current to loads such as DC motors, stepping motors, relays and solenoids. It is one of the most widely used ICs for controlling small to medium DC motors from a microcontroller in robotics and automation projects.

Capable of running two DC motors simultaneously with full speed and direction control, the L293D can also switch at frequencies up to 5kHz, making it suitable for PWM-based speed control as well as simple on/off driving. Its high-noise-immunity inputs and internal ESD protection make it a robust choice for real-world project builds.

• Function – Drives two DC motors simultaneously
• Control – Full speed and direction control
• Output current – 600mA per driver channel
• Input protection – High-noise-immunity inputs with internal ESD protection
• Supply voltage – Single supply from 4.5V to 36V
• Switching frequency – Up to 5kHz
• Operating temperature – 0°C to 70°C

Designed to control motors operating anywhere from 4.5V to 36V with drive currents up to 600mA, the L293D is a versatile core component for robotics, automation and any project involving bidirectional motor control. The L293D Motor Driver IC remains a go-to choice for hobbyists and engineers building motor-driven electronics.
