Description

L293D – Dual H-Bridge Motor Driver IC

📄 Description:

The L293D is a versatile quad half-H driver, typically used to drive two DC motors or one stepper motor in both directions. Designed using bipolar technology, it can source or sink up to 600mA per channel (1.2A peak) and supports motor voltages up to 36V.

With built-in internal clamp diodes, TTL logic compatibility, and separate logic and motor power supplies, the L293D is ideal for compact motor control projects and is widely used in Arduino and robotics applications.

📐 Specifications:
