  • 品牌:NXP(恩智浦)

二 关键特性与优势

  • 宽输入电压:5 V 至 18 V 的供电范围使器件能稳定工作于传统 12 V 车载系统及更高电压场景(例如 24 V 商用车环境),提高设计灵活性。
  • 低功耗设计:典型工作电流 1.6 mA,待机静态电流仅 10 μA,适合需要待机节能的体域网络与门控模块,降低整车待机功耗。
  • 良好的输入滞后:接收器滞后 175 mV,有助于提高网络抗干扰能力,改善总线噪声条件下的可靠通信。
  • 宽温度工作范围:-40 ℃ 至 +150 ℃ 的工作温度等级适应发动机舱等高温环境,满足严苛的汽车环境要求。
  • ESD 抗扰度:±8 kV 的静电保护水平增强了总线接口的鲁棒性,提高设计的可靠性与生产一致性。
  • 集成化封装:SOIC-8 市场常见封装,便于 PCB 布局与自动化贴装,支持批量生产与维修更换。

三 典型应用场景

  • 车身电子(Body Electronics):车门控制单元、车窗升降、门锁与照明控制等体域通信。
  • 后视镜与座椅:电动调节、折叠与记忆功能模块的联网控制。
  • 车内传感器接口:温度、位置、占用感应等分布式传感器与执行器的通信节点。
  • 舱内控制单元(HVAC、仪表台等):作为成本有效的局域网络收发端,实现主控器与从属节点的数据交换。
  • 商用车和特殊车辆:宽电压支持使其也适用于 24 V 系统的车辆电子网络。

四 设计与使用建议

  • 总线连接:作为 LIN 总线的收发器,建议按 LIN 网络的拓扑和规范设计总线终端电阻与上拉结构,确保处于主从配置中的正确复位与唤醒行为。
  • 电源旁路:为保证稳定通信与抗干扰性能,建议在器件电源引脚附近放置合适的去耦电容,减小瞬态响应。
  • EMC 与接地:总线布线应注意屏蔽与接地策略,尤其在车载电磁噪声较高的区域,应结合滤波与布局优化减小干扰。
  • 热管理:尽管器件支持高温工作,模块布局仍需要考虑散热与器件周边热源,避免长期超额温度应力。
  • ESD 防护:虽然器件内部具有 ±8 kV ESD 抗扰能力,生产与维修阶段仍建议采取常规静电防护措施。

五 封装与采购信息

TJA1027T/20,118 采用标准 SOIC-8 封装,便于在常规 PCB 工艺下实现小型化与自动化组装。采购时请确认型号与版本后缀,以匹配目标车辆系统的环境与认证需求;在可靠性与供应方面,可直接参考 NXP 官方资料与代理渠道获取最准确的技 术手册、封装尺寸与焊接建议。

总结:TJA1027T/20,118 为面向汽车应用的高可靠性 LIN 收发器,凭借宽电压范围、低待机功耗、高温等级与良好的 ESD 抗扰能力,适合多种车载网络节点的通信接口设计,为车身电子与分布式控制系统提供稳定、低成本的通信解决方案。若需详细电气特性曲线、引脚功能或参考设计建议,可参考 NXP 官方数据手册或联系技术支持。

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
