CTM1051AT 产品概述

一、产品简介

CTM1051AT 是易川(YLPTEC)推出的一款隔离型 CAN 总线收发器,面向工业现场总线、分布式控制与数据采集等对电气隔离和可靠性有较高要求的系统。器件支持最高 1 Mbps 的 CAN 数据速率,工作于 3.3V 电源(允许范围 3.15V~3.45V),采用方便插装的 DIP-7 封装,便于开发、维护与替换。

二、主要技术参数

  • 输出接口:CAN 接口(差分 CANH / CANL)
  • 数据速率:最高 1 Mbps
  • 隔离类型:带隔离(器件内部实现总线侧与逻辑侧的隔离)
  • 工作电压:3.15V ~ 3.45V(典型 3.3V)
  • 静态电流(Iq):20 mA(常态工作电流)
  • 功能特性:显性超时(dominant timeout),防止总线长时间被拉低而导致通信阻塞
  • 封装:DIP-7,便于插针式装配与原型开发

三、功能特性与工作机理

CTM1051AT 作为物理层收发器,完成 MCU/控制器的单端逻辑信号与差分 CAN 总线信号之间的转换。显性超时功能在发送端持续驱动差分线上出现异常(例如外部短路或内部卡死)时,会在超时后自动释放驱动,避免总线长期处于显性态(dominant),从而提高系统的容错性与可恢复性。隔离功能则隔离了地回路与高差电位,保护主控与现场总线之间不受共模干扰与瞬态冲击影响,提升系统稳定性与抗干扰能力。

四、典型应用场景

CTM1051AT 适用于需要电气隔离且传输速率至 1 Mbps 的场景,例如:

  • 工业自动化与分布式 I/O 网络
  • 楼宇自控与安防监控系统
  • 仪器仪表与数据采集单元
  • 可再生能源与智能电网监控节点
  • 现场节点与网关间的隔离通信

(注:若用于关键安全或车载主系统,请参考相关认证与环境可靠性要求。)

五、实用建议与布局注意事项

  • 电源与旁路:在逻辑侧与总线侧均应使用低 ESR 陶瓷电容做靠近器件的旁路(例如 0.1 µF),以抑制瞬态噪声。
  • 总线终端:差分总线两端应并行 120 Ω 终端电阻;长线路或高干扰环境下建议配合共模电感与 TVS 二极管做保护。
  • 隔离注意:虽然器件带隔离,但外部布线应保持隔离区域的爬电距离与绝缘要求,避免通过接插件产生不期望的接地回路。
  • 故障诊断:利用显性超时功能可配合软件超时与重试机制,快速定位节点异常并恢复通信。
  • 温度与散热:DIP 插装便于散热检测,但在高温环境下仍需评估器件功耗(静态 20 mA),并做好散热与环境保护。

六、封装与选型建议

CTM1051AT 提供 DIP-7 贯穿孔封装,适合试验板、替换与中小批量生产。选型时应确认所用系统的电压范围(确保 3.15V~3.45V 兼容)、是否需要通过隔离等级认证(例如工业冗余或安规要求)以及对 ESD/浪涌保护的额外需求。对于需要表贴或更高集成保护的场合,可联系供应商了解同系列其它封装或增强型产品。

总结:CTM1051AT 以其 1 Mbps 的速率、3.3V 工作电压、带隔离设计和显性超时保护,适合用于对可靠性和电气隔离有要求的工业与嵌入式 CAN 网络节点,DIP-7 封装也为开发与维护提供了便利。详细引脚定义与电气特性请参照产品规格书以保证设计兼容性。

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
