ULN2003ADR(LX) 产品概述
一、产品概述
ULN2003ADR(LX) 是灵星芯微（LX）推出的七路达林顿晶体管阵列，采用 SOP-16 封装，集成基极限流电阻与共用反并联续流二极管（用于感性负载保护）。每通道为达林顿对结构，可作为低侧开关直接驱动继电器、电磁阀、步进电机、指示灯及各种感性/阻性负载，对上位微控制器接口友好，便于系统集成与缩小 PCB 面积。
二、主要电气参数
- 通道数：7 路
- 集-射极击穿电压 Vceo：50 V
- 单通道集电极电流 Ic（峰值）：500 mA（请参照散热条件与占空比设计）
- 最大输入电压 VI：30 V
- 工作温度范围：-40 ℃ ～ +85 ℃
- 集电极漏电流 Icex：50 μA（典型/最大漏电随测试条件而变）
- 输入电流（导通）Ion：0.4 mA（在规定输入电压下的基极限流表现）
- 反向电流 Ir：50 μA（输入/输出的反向漏电特性）
三、特性与优势
- 七路集成，节省 PCB 空间与器件数量。
- 内置基极限流电阻，直接与 TTL/CMOS/微控制器兼容，无需外部限流电阻。
- 支持高达 50 V 的输出耐压，适合多数工业电源与继电器线圈。
- 内置续流二极管（COM 引脚）便于驱动感性负载，减少外部保护元件。
- SOP-16 标准封装，便于贴片生产与自动化组装。
- 性能稳定，工作温度范围宽，适用于工业级应用。
四、封装与引脚说明
- 封装：SOP-16（表面贴装）
- 常见引脚分配：一侧为 7 个输入引脚，另一侧为对应 7 个输出引脚；此外有公共二极管连接点（COM）与接地（GND）引脚。
- 使用时请将 COM 与供电正极连接以发挥续流二极管保护功能，GND 与系统地连接。
五、典型应用场景
- 继电器驱动、继电器阵列控制
- 步进电机低侧驱动（配合步进驱动策略）
- 直流电机小功率驱动与方向控制（非高速精密场合）
- LED/指示灯阵列驱动、灯光矩阵低侧开关
- 工业控制、仪器仪表与家电中的驱动接口
六、使用建议与注意事项
- 请确保单通道电流、封装散热能力与实际负载匹配，连续大电流场合注意热设计与散热。
- 感性负载时务必接好 COM，以便续流二极管工作，避免器件损伤。
- 输入电压不要超过 30 V，输出/集电极电压不超过 50 V。
- 留意漏电流（Icex、Ir）对高阻或精密电路的影响，必要时增加上拉/下拉电阻进行隔离。
- 为保证可靠性，建议参考厂商数据手册中的典型波形与额定条件进行电路设计与验证。
如需引脚图、典型应用电路图或更多电气特性曲线，可提供进一步资料以便给出更详细的设计建议。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
