HG3485EIM/TR 产品概述

一、产品简介

HG3485EIM/TR 是华冠(HGSEMI)推出的一款低功耗差分收发器,单驱动器、单接收器,采用 SOP-8 封装,工作电压范围 3.0V ~ 3.6V,支持半双工差分通信,数据速率可达 10Mbps。器件工作温度范围为 -40℃ ~ +85℃,静态电流仅 500µA,适合工业级和嵌入式现场总线应用。

二、主要特性

  • 单驱动器、单接收器配置,半双工通信模式。
  • 工作电压:3.0V ~ 3.6V,兼容 3.3V 系统。
  • 最高数据速率:10Mbps,满足高速差分链路要求。
  • 总线节点:支持多达 32 节点连接,便于组网扩展。
  • 静电保护:端口 ESD 抗扰度 ±15kV(空气放电或接触放电等级),适配工业现场静电环境。
  • 工作温度:-40℃ 到 +85℃,满足宽温应用场景。
  • 低静态电流:待机电流约 500µA,利于低功耗设计。
  • 封装:SOP-8,HG3485EIM/TR 中 TR 通常表示卷带包装,适合自动化贴片生产。

三、功能与应用场景

HG3485EIM/TR 为差分半双工收发器,适用于需要鲁棒链路和长距离通信的场合,典型应用包括:

  • 工业自动化现场总线与控制网络;
  • 建筑楼宇控制与安防系统;
  • 仪器仪表与数据采集(DAQ)模块;
  • 电机驱动与运动控制通信;
  • 电力监控与表计抄表系统。

器件与差分总线(如 RS-485 类)兼容,可在多节点系统中提供稳定的数据传输能力。

四、设计要点与建议

  • 总线布线:差分对采用对称线缆、控制阻抗并尽量缩短回路,远端建议并联终端电阻(典型 100Ω~120Ω,根据线路阻抗选择)。
  • 偏置与故障安全:在多节点网络中应采用合适的终端偏置和上拉/下拉方案以保证总线空闲时输出稳定;如需更高可靠性,可在主控端实现上拉/下拉偏置网络。
  • 电源与去耦:3.3V 电源侧推荐在 VCC 附近放置 0.1µF 陶瓷去耦电容,并考虑输入滤波以降低干扰。
  • ESD 与防护:器件已具较高静电保护能力,但在高干扰环境仍建议在物理接口处增加瞬态抑制元件(TVS)和共模电感以增强系统稳健性。
  • 热管理与布局:SOP-8 封装在高密度布线时应注意散热路径与焊盘完整性,满足环境温度要求下的长期可靠性。

五、电气与可靠性要点

  • 静态电流(待机):约 500µA,利于电池或低功耗系统。
  • 数据速率与节点数:10Mbps、最多 32 节点,适合中高速、多点通信拓扑。
  • 温度与抗干扰:工业级温度范围和 ±15kV ESD 抗扰能力,使该器件适配苛刻的工业环境。

六、封装与订购信息

型号:HG3485EIM/TR
封装:SOP-8(标准 8 引脚)
包装:TR 表示卷带(Tape & Reel),便于 SMT 自动化贴装生产。
选型时建议参考完整数据手册中的引脚说明、电气特性曲线及推荐焊盘尺寸,以便布局与生产一致性。

总结:HG3485EIM/TR 是一款面向工业与嵌入式差分半双工通信的低功耗、高抗扰收发器,兼顾性能与可靠性,适用于现场总线、楼宇自控与各种多节点差分通信系统。若需进一步的管脚图、时序图或典型电路,请提供具体需求以便给出更详细的设计资料。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
