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:

Parameter Value
Motor Supply Voltage (V<sub>s</sub>) 4.5V – 36V
Logic Supply Voltage (V<sub>ss</sub>) 4.5V – 7V
Output Current per Channel 600mA continuous
Peak Output Current 1.2A (non-repetitive)
Logic Input Compatibility TTL/CMOS
Output Clamp Diodes Internal
Control Inputs IN1, IN2, IN3, IN4
Enable Pins EN1 (Motor A), EN2 (Motor B)
Package Types DIP-16 / SOIC-16
Operating Temperature -0°C to +70°C
