概述

Description

The ULQ2003AN is a high-voltage, high-current Darlington transistor array designed to interface between low-voltage logic circuits and higher voltage loads. This integrated circuit contains seven pairs of Darlington transistors, allowing it to control multiple outputs with a single input signal. It is ideal for driving motors, lamps, and relays directly from microcontrollers or other low-power devices.
Key features include a wide supply voltage range (up to 50V), high current output capability (up to 500mA per channel), and built-in flyback diodes that protect against voltage spikes when switching inductive loads. The ULQ2003AN typically comes in a standard DIP-18 package, making it easy to integrate into various electronic projects.
Applications include robotics, automation systems, and any scenario where control of higher power devices is necessary with limited input signal power. The ULQ2003AN simplifies circuit design and reduces component count, making it a popular choice among engineers and hobbyists alike.
