    Description

    The ULN2803 SOIC-18 is an 8-channel Darlington transistor array driver IC designed to drive high-current loads using low-voltage logic signals. It contains 8 NPN Darlington pairs with built-in flyback diodes, making it ideal for controlling relays, solenoids, stepper motors, LED strips, and other inductive loads.

    This IC is widely used in Arduino, ESP32, microcontroller projects, automation boards, robotics, and industrial control systems.

    Applications

    • Relay driver circuits

    • Stepper motor driver interface

    • Solenoid and valve control

    • LED strip / lamp driver

    • Robotics and automation

    • Microcontroller output expansion
