COS13487EESA 产品概述

一、产品简介

COS13487EESA 是 COSINE(科山芯创)推出的一款 RS-485/RS-422 半双工收发器,集成 1 路驱动器与 1 路接收器,支持 500 kbps 数据速率。器件工作电压宽范围 3.0V~5.5V,适配 3.3V 和 5V 系统,封装为 SOP-8,面向工业级多点差分通信场景。

二、主要特性

  • 自动方向控制,省去外部 DE/RE 管理,简化主控设计
  • 独立 Tx/Rx 启用管脚,支持软件级使能管理与省电
  • 数据速率最高 500 kbps,最多可支持 256 节点的总线拓扑
  • 低静态电流:典型 770 μA,适合低功耗应用
  • 工作温度范围:-40℃ ~ +125℃,满足工业级可靠性要求

三、保护与可靠性

  • 静电防护:±15 kV(静电放电防护能力)
  • 热关断保护与过流保护,防止短路或过载损坏器件
  • 热插拔保护,降低设备插拔时对总线及终端器件的冲击
  • 使能关断功能,可在不使用时关断以进一步降低系统功耗

四、电气与拓扑建议

  • 差分对线上建议在接收端或长度匹配处并联 120 Ω 终端电阻以保证信号完整性
  • 在设备电源侧靠近 VCC 引脚放置 0.1 μF 陶瓷去耦电容以抑制供电毛刺
  • 采用差分对长度匹配与屏蔽布线,可抑制共模干扰并提升传输稳定性

五、典型应用

  • 工业现场总线、楼宇自控、过程控制与数据采集(DAQ)
  • 多节点仪器仪表与远程传感网络
  • 能源计量与电力监控系统,要求长线可靠通信的场合

六、封装与订购信息

  • 封装:SOP-8
  • 推荐型号:COS13487EESA(COSINE/科山芯创)
  • 可为不同封装或测试需求提供技术支持与应用参考电路

七、设计注意事项

  • 若系统对瞬态抑制有更高要求,可在差分对引脚外增加公共模式共模扼流或 TVS 器件
  • 在多节点总线中,确保仅两端终端并避免多个终端并联导致阻抗不匹配
  • 利用器件的 Tx/Rx 使能功能配合主控固件,实现总线仲裁与低功耗管理

COS13487EESA 以自动方向控制与多重保护机制为核心,提供工业级可靠性与简化的总线管理方案,适合需要高可靠差分链路的多点通信系统。若需数据手册(Datasheet)、典型应用电路或 PCB 布局建议,可联系科山芯创获取更详细资料。

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.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
