TJA1050TM/TR 产品概述

一 概述

TJA1050TM/TR 为HGSEMI(华冠)推出的高速 CAN 总线收发器,适用于需稳定、可靠差分通信的现场总线应用。器件支持最高1 Mbps 的数据传输速率,工作电压范围为 4.5 V 至 5.5 V,典型工作电流约 3 mA,工作温度范围 -40 ℃ 至 +85 ℃,封装为 SOP-8,适合汽车电子、工业控制及其他恶劣环境下的串行通信节点。

二 主要特性

  • 支持高速 CAN 通信,最高 1 Mbps 数据速率。
  • 供电范围宽:VCC = 4.5 V ~ 5.5 V,便于与 5 V 系统兼容。
  • 低工作电流:典型 3 mA(空载或待机视具体工作状态而定)。
  • 工作温度覆盖工业级:-40 ℃ ~ +85 ℃。
  • 封装:SOP-8,便于自动化贴装与常规 PCB 布局。
  • 常见高速收发器功能:差分驱动/接收、总线故障容限与静态故障处理(具体保护特性请参考详细数据手册)。

三 电气与硬件设计建议

  • 电源旁路:在 VCC 与 GND 之间靠近器件焊盘放置 0.1 μF 贴片电容,并可并联 1 μF~10 μF 的去耦电容来抑制瞬态干扰。
  • 总线终端:CAN_H 和 CAN_L 两端建议使用 120 Ω 差分终端电阻(总线两端各一个),以保证波形完整性与回波抑制。
  • 布线要点:CAN_H/CAN_L 差分对走线长度相等、间距固定、尽量靠近平面电源/地层,避免穿越分割地或大功率走线。
  • 浪涌与静电保护:在总线上推荐并联 TVS 二极管与共模扼流圈以提高抗扰度,器件本身亦应按数据手册布置 ESD 保护和短路限流措施。
  • 接口兼容:TXD/RXD 与主控 MCU 的逻辑接口保持电平兼容,必要时加入 RC 滤波以改善 EMI。

四 应用场景

  • 汽车车身控制、仪表盘与底盘通信节点;
  • 工业自动化网络、PLC 与远程 I/O 模块间通信;
  • 建筑自动化、安防与楼宇控制系统;
  • 电机控制、数据采集与其它需要抗干扰差分通信的场合。

五 选型与封装信息

TJA1050TM/TR 名称中常见 TM/TR 后缀表示不同的包装形式(如管装/卷带),便于批量生产与 SMT 贴装。封装为 SOP-8,有利于替换市场上常见的高速 CAN 收发器。选型时注意与系统的电压、温度等级、EMC 要求及是否需要额外保护器件(如 TVS、共模电感)作配套。

六 使用注意事项

  • 确认系统总线拓扑与终端匹配,防止中间节点误用终端电阻。
  • 在高噪声环境(如点火、电机驱动附近)应加强滤波与屏蔽;必要时采用隔离型收发器。
  • 参考厂商完整数据手册核对引脚排列、绝对最大额定值与热特性,避免超限工作导致失效。

总结:TJA1050TM/TR 是面向高速 CAN 总线的实用型收发器,凭借 1 Mbps 的带宽、工业级温度范围与 SOP-8 可装封装,适合广泛的汽车和工业应用。在实际设计中配合合理的电源去耦、总线终端与浪涌保护,能够提供稳定可靠的差分通信性能。若需进一步电气特性(引脚定义、时序、故障响应等)与典型波形,请参考器件的详细数据手册或向供应商索取应用笔记。

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
