COS13488EESA 产品概述

一、概述

COS13488EESA 是科山芯创(COSINE)推出的一款高可靠性 RS-485/RS-422 半双工收发器。器件集成 1 路驱动器和 1 路接收器,工作电压范围宽(3.0 V ~ 5.5 V),具有自动方向控制功能,省去外部隔离方向控制信号线,简化了 MCU 或主控逻辑的设计。器件提供热插拔保护、热关断保护与使能关断功能,并具备低功耗运行模式,适合工业总线、楼宇自控、仪器仪表等对可靠性和抗干扰要求高的应用场景。

二、主要规格与特性

  • 类型:半双工收发器(RS-485/RS-422 兼容)
  • 驱动器数 / 接收器数:1 / 1
  • 工作电压:3.0 V ~ 5.5 V
  • 数据速率:支持高达 16 Mbps(在常见工业配置下典型速率为 12 Mbps)
  • 节点数:最多支持 256 个节点
  • 静态电流:典型 700 μA(低功耗模式下)
  • 静电保护:±15 kV(人体模型 HBM)
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 通讯模式:半双工
  • 包装形式:SOP-8(表面贴装)
  • 特色功能:自动方向控制、热插拔保护、热关断保护、使能关断、低功耗模式

三、功能亮点说明

  1. 自动方向控制
    内置方向检测与自动切换逻辑,收发器能根据发送/接收数据流自动控制驱动器的工作状态,消除了对外部 DE/RE 控制线的依赖,降低系统 IO 占用与软件复杂度。

  2. 热插拔保护
    在现场接入或拔出节点时,器件对总线瞬态冲击具有抑制能力,减少对其他节点造成干扰,提高设备热插拔可靠性。

  3. 热关断保护与过温保护
    器件具备温度保护机制,当内部温度超过安全阈值时自动限流或关断输出,防止因短路或过载导致器件损坏,保障系统安全运行。

  4. 使能关断与低功耗模式
    外部使能引脚可将收发器置于关闭状态,配合低功耗模式使静态功耗降至典型 700 μA,适合总线节点数量大、需节能运行的系统。

四、电气与可靠性要点

  • 宽电源范围(3.0 V ~ 5.5 V)保证兼容不同逻辑电平与系统电源设计。
  • ±15 kV HBM 级别的静电保护提高现场使用的抗干扰能力,适合工业环境。
  • -40 ℃ 至 +125 ℃ 的工作温度覆盖恶劣环境应用需求。
  • 支持大节点数(多达 256 节点),适用于长线、多终端总线拓扑。

五、典型应用场景

  • 工业自动化现场总线(PLC 与从站通信)
  • 楼宇自控与安防系统(门禁、监控设备网络)
  • 仪器仪表与数据采集模块(多点采样、低功耗节点)
  • 电机控制与驱动器网络(现场总线通信)
  • 串行通信扩展接口与转接模块

六、设计与使用建议

  • 总线终端:在总线两端采用适当阻值(典型 120 Ω)的终端电阻以匹配差分阻抗,减少信号反射。
  • 失效保护偏置:建议在长线系统中使用失效保护偏置电阻(fail-safe bias)保证空闲总线时接收端输出为确定电平。
  • 电源去耦:在 VCC 与 GND 之间靠近器件并放置 0.1 μF 陶瓷去耦电容,以抑制供电瞬态。
  • 布线注意:差分信号 A/B 尽量成对、等长度布线,避免长分支和大面积环路。
  • 热管理:在高负载或多节点通信频繁场景,合理考虑器件散热路径,配合过温保护使用。

七、封装与型号

  • 型号:COS13488EESA
  • 封装:SOP-8(兼容常见 SMT 工艺,便于批量贴装与更换)

COS13488EESA 以其自动方向控制、宽电压、强抗静电与高工作温度等特性,为工业级半双工差分总线提供了可靠且易用的收发解决方案。选择本器件可显著简化主控设计、提升系统鲁棒性并降低现场维护难度。若需详细管脚定义、电气特性曲线及参考电路图,请参考 COSINE 官方数据手册或联系当地技术支持获取完整资料。

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
