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。
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。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
