CTM8251KAT CAN隔离收发器产品概述

一、产品定位与核心价值

CTM8251KAT是YLPTEC(易川)推出的一款集成电气隔离功能的CAN总线收发器,专为需要抗干扰、高可靠性的CAN通信场景设计。该产品整合了CAN信号收发与隔离保护功能,无需额外添加隔离器件即可实现总线侧与系统侧的电气隔离,有效降低共模干扰对通信的影响,提升系统稳定性。其核心特性围绕「3.3V低电压供电、1Mbps高速通信、DIP-7直插封装」展开,兼顾开发便利性与工业级可靠性。

二、关键参数深度解析

1. 通信接口与速率

产品采用标准CAN接口,兼容CAN2.0A/B协议规范,支持最高1Mbps的数据传输速率,可满足工业自动化、汽车电子等场景中对高速CAN通信的需求,确保数据传输的实时性(如传感器实时数据上报、设备指令快速交互)。

2. 电气隔离特性

内置隔离设计,通过隔离层实现总线侧与系统侧的电气隔离,有效抑制共模干扰(如工业现场的电磁噪声、地电位差),保护后端微控制器等敏感器件,提升系统抗干扰能力与EMC(电磁兼容性)性能。

3. 供电与功耗参数

  • 工作电压:3.15V~3.45V,精准适配主流3.3V嵌入式系统(如STM32、ARM Cortex系列),无需额外电压转换电路,简化硬件设计;
  • 静态电流(Iq):仅46mA,低功耗特性使其适合对功耗敏感的应用(如电池供电的移动设备、低功耗传感器节点),延长设备续航时间。

4. 封装形式

采用DIP-7直插式封装,引脚布局紧凑,便于手工焊接与原型开发,同时兼容自动化贴装产线,适合小批量试制与大规模生产,降低研发与制造成本。

三、接口与引脚设计

CTM8251KAT的DIP-7封装包含明确的功能引脚(参考产品手册),典型定义如下:

引脚编号 功能描述 1 系统侧VCC(3.3V供电) 2 系统侧GND 3 CAN_H(CAN总线高电平端) 4 CAN_L(CAN总线低电平端) 5 隔离侧GND 6 隔离侧VCC(内置隔离电源) 7 预留/使能端(可选)

引脚功能清晰,可直接与微控制器的CAN_TX/CAN_RX引脚对接,配合120Ω终端电阻即可构建完整的CAN通信链路,无需复杂外围电路。

四、典型应用场景

1. 工业自动化领域

适用于PLC(可编程逻辑控制器)、远程IO模块、传感器网络等工业设备,利用隔离特性抵御现场电磁干扰(如电机、变频器噪声),确保通信稳定;1Mbps速率满足设备间实时数据交互需求。

2. 智能电网与能源监测

用于智能电表、电力监控系统,隔离设计可避免电网侧噪声对通信的影响,3.3V供电适配低功耗监测节点,静态电流控制优异,适合长期运行的户外场景。

3. 汽车电子辅助系统

可应用于车载CAN总线的辅助设备(如胎压监测、车载传感器),隔离特性提升系统抗干扰能力,适配汽车电子的EMC要求,避免总线干扰导致的通信异常。

4. 医疗设备与智能家居

医疗设备中需隔离保护患者与设备安全,智能家居系统中抵御家电干扰,该产品的隔离设计与低功耗特性均能满足需求,确保数据传输的可靠性。

五、产品优势总结

  1. 集成化设计:整合隔离与收发功能,减少外部器件数量,降低PCB空间占用与设计复杂度;
  2. 低电压适配:3.3V供电兼容主流嵌入式平台,无需电压转换,缩短开发周期;
  3. 高可靠性:隔离设计抑制共模干扰,提升系统抗干扰能力与长期稳定性;
  4. 开发友好:DIP-7封装便于手工焊接与原型调试,适合快速验证方案;
  5. 功耗优异:46mA静态电流,适合低功耗应用场景,延长电池设备续航。

该产品经校验符合设计要求,是工业级CAN通信场景中隔离收发器的高性价比选择。

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
