COSMAX13487EESA 产品概述

一、产品简介

COSMAX13487EESA(品牌:COSINE / 科山芯创)是一款高可靠的RS-485/RS-422半双工收发器,集成1路驱动器与1路接收器,工作电压范围宽(3.0V~5.5V),最大数据速率可达500kbps。器件采用SOP-8封装,面向工业级应用,工作温度范围为-40℃至+85℃,适合严格环境下的现场总线应用。

二、主要功能与特性

  • 自动方向控制:器件内部实现自动转向逻辑,免去外部方向控制通道,简化主控器件GPIO占用与固件设计。
  • 热插拔保护:支持热插拔场景,减少插拔瞬态对系统总线的影响,提高系统可靠性。
  • 热关断保护:当器件过热时会进入保护模式,避免损坏并提升整机安全性。
  • 使能关断:支持外部使能控制,实现断电或低功耗待机,便于能耗管理。
  • 高ESD抗扰:差分总线端口静电保护等级可达±15kV(人体模式),增强现场抗扰能力。
  • 低静态功耗:典型静态电流约700μA,适合电源受限或常时在线的工业节点部署。
  • 节点支持:单总线最多支持256节点,适用于大规模分布式网络。

三、电气与系统设计要点

  • 差分总线布线建议使用双绞线并在总线两端并联终端电阻(典型120Ω),以抑制信号反射。
  • 为保证空闲总线可预测性,建议配合失效保护(fail-safe)偏置电阻或终端偏置网络。
  • 在热插拔或高噪声环境下,可适当增加外部共模滤波与浪涌抑制器件(如TVS)以提升抗扰性能。
  • 封装为SOP-8,布局时注意散热路径与差分对等长布线,避免长走线干扰和延时不匹配。

四、典型应用场景

  • 工业自动化现场总线与PLC通讯节点
  • 楼宇自控与安防系统的长距离数据链路
  • 仪器仪表、能源计量与分布式控制系统
  • 需要热插拔或频繁维护的工业设备现场接口

五、优势小结

COSMAX13487EESA凭借自动方向控制与全面的保护特性(热插拔、热关断、使能关断),在减少系统复杂度、提升可靠性与抗扰性方面表现突出。其宽电压与工业温度等级、低静态功耗和高ESD抗扰能力,使其成为工业现场RS-485/RS-422半双工通讯的可靠选择。

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
