TJA1044GTK/3 产品概述

一 概述

TJA1044GTK/3 为恩智浦(NXP)推出的 CAN 接口收发器,面向车规与工业级高速 CAN 总线应用。器件采用 HVSON8 封装并提供卷盘(REEL)出货形式,型号常见标注为 TJA1044GTK/HVSON8//3/REEL。该器件工作电压为 4.5V ~ 5.5V,静态/工作电流典型值约 60mA,额定工作温度范围为 -40℃ ~ +150℃,适用于高温、严苛环境的设计需求。

二 主要特性

  • 支持高速 CAN 差分收发,兼容标准 CAN 总线物理层;
  • 单电源供电,工作电压范围 4.5V ~ 5.5V,适配常见 5V 系统;
  • 工作电流典型值 60mA(设计选型时请参考数据手册的最大/典型功耗曲线);
  • 宽温度等级:-40℃ 至 +150℃,适应汽车与重载工业环境;
  • 封装与交付:HVSON8 封装,卷带(Reel)供货,便于自动贴装与量产。

(器件常见功能如总线容错、短路/热保护、低功耗待机等,请以厂商数据手册为准。)

三 电气与环境参数(关键项)

  • 供电:VCC = 4.5 ~ 5.5 V;
  • 工作电流:约 60 mA(典型);
  • 工作温度:-40 ℃ ~ +150 ℃;
  • 接口:差分 CANH/CANL 总线端口,与 MCU 的 TX/RX 或控制逻辑相连;

在工程开发中,应以官方数据手册提供的各项极限值、电平容差、传输速率和时序为最终依据。

四 典型应用场景

  • 车载电子控制单元(ECU)、车身控制模块、仪表与网关;
  • 工业自动化与运动控制系统中的现场总线接口;
  • 商用车与工程机械等需要耐高温与抗干扰能力的通讯节点;
  • 需要与标准 CAN 总线互连的诊断与测试设备。

五 设计建议与注意事项

  • 电源去耦:VCC 旁靠近器件引脚放置 100 nF 陶瓷电容,必要时并联更大容量电容以抑制瞬态;
  • 总线终端:在 CANH 与 CANL 之间使用 120 Ω 终端电阻,节点布局尽量采用差分对并保持阻抗一致;
  • 布线与共模:差分线对应尽量短并同侧过孔,避免在高频处跨地分割;必要时加装共模电感/滤波以降低 EMI;
  • 温度与散热:器件允许高温工作,但长时间高温下应关注 PCB 热路径与可靠性试验,符合制造工艺的回流焊工艺曲线;
  • 保护与检测:应用中可并联 TVS 或浪涌保护器件以应对瞬时过压;在系统开发阶段进行总线短路、浪涌与 ESD 测试验证。

六 包装与获取

  • 制造商:NXP(恩智浦);
  • 型号:TJA1044GTK/3(常见标识 TJA1044GTK/HVSON8//3/REEL);
  • 封装:HVSON8;供货形式:卷盘(Reel),适合 SMT 自动化贴装;
  • 采购与样品:建议向官方渠道或授权分销商获取,并查验最新数据手册与可靠性认证资料。

七 结论与建议

TJA1044GTK/3 以其 5V 工作域、60mA 级别功耗与宽温范围(-40℃ ~ +150℃)为车规与工业级 CAN 通讯提供稳健的物理层解决方案。设计时应严格参照 NXP 官方数据手册完成电气、热与可靠性验证,并在系统级加入必要的去耦、终端与保护电路以确保长期稳定运行。如需完整引脚定义、时序、典型应用电路与保护特性,请获取并阅读器件的最新数据手册。

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
