TJA1028T/5V0/20/1J 产品概述

一、产品简介

TJA1028T/5V0/20/1J 是恩智浦(NXP)推出的一款半双工 LIN 总线收发器,封装为 SO-8,定位于车载局域网(LINbus)节点的物理层接口。器件在 5V 电源下工作,兼顾低功耗与工业级温度范围,适用于对可靠性和抗干扰能力有较高要求的车载控制单元(ECU)与传感器模块。

二、主要技术参数

  • 类型:收发器(半双工 1:1 LINbus)
  • 工作电压:4.9 V ~ 5.1 V
  • 接收器滞后(Hysteresis):200 mV
  • 工作电流:约 4.5 mA(工作模式)
  • 静态电流(待机/休眠):约 59 µA
  • 工作温度范围:-40 ℃ ~ +150 ℃
  • 封装:SO-8
  • 静电保护(ESD):±8 kV(人体模型)

三、功能特点

  • 低功耗设计:在待机/休眠模式下静态电流仅 59 µA,有利于整车低功耗管理与电池寿命延长。
  • 稳定的接收性能:200 mV 的接收器滞后保证了抗抖动能力和噪声容限,提升总线通信的可靠性。
  • 宽温度适应性:-40 ℃ 到 +150 ℃ 的工作温度覆盖了严苛汽车环境下的长期使用需求。
  • 良好的抗静电能力:±8 kV 的 ESD 抗扰性能减小装配与维护过程中的损伤风险。
  • 标准化接口与封装:SO-8 封装便于在现有 PCB 布局中替换与集成。

四、典型应用场景

  • 车门控制单元、车窗/座椅调整控制器等车载子模块的 LIN 总线通信接口。
  • 车内传感器、开关和灯光控制等低速网络节点。
  • 需要低功耗待机并能承受高温的汽车环境电子设备。

五、封装与可靠性

SO-8 封装便于自动化贴装与散热设计,器件本身支持宽温工作且具备工业级 ESD 保护,满足汽车电子对可靠性、耐温和抗扰度的严格要求。建议在 PCB 设计中为 LIN 总线引脚增加适当的串联阻抗与共模抑制措施,以提升系统级电磁兼容性。

六、选型建议与注意事项

  • 若系统供电严格为 5 V,TJA1028T/5V0/20/1J 可直接替代;若需更宽的电源容差,应核对替代型号参数。
  • 在高电磁干扰环境下,可配合外部滤波和 TVS 保护器件提升抗扰能力。
  • 注意在焊接和存储过程中遵循器件的静电防护规范以防损伤。
  • 对于对总线故障保护、过温保护等特殊需求,请在系统层面验证器件行为并参考恩智浦完整数据手册进行最终设计验证。

如需完整电气特性曲线、封装尺寸和等效电路图,可提供数据手册参考,便于在原理图与 PCB 设计中精确应用。

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
