TJA1021T/10/C,118 产品概述

一、产品简介

TJA1021T/10/C,118 是恩智浦(NXP)推出的完全版 LIN 总线收发器,封装为 SO-8,集成 1 个驱动器与 1 个接收器,适用于车载和工业低速串行通信节点。该器件针对具有严格功耗与抗干扰要求的系统设计,提供宽工作电压范围与低静态电流特性,便于在多种供电环境下稳定工作。

二、主要参数与特性

  • 类型:收发器(1 驱动 / 1 接收)
  • 工作电压:5.5 V ~ 27 V,适应 12V 与 24V 系统的瞬态与稳态变化
  • 接收器滞后(接收门限滞后):175 mV,有利于抗抖动与噪声抑制
  • 工作电流:典型 4 mA,适合常规工作模式下低功耗需求
  • 静态(待机)电流:10 μA,可实现节点休眠以降低系统待机损耗
  • 静电保护:对差分与单端干扰具备 ±6 kV 抗静电能力,提升系统可靠性
  • 封装:SO-8,便于批量生产与 PCB 布局

三、优势与应用场景

凭借宽电压范围与超低静态电流,TJA1021T/10/C,118 非常适合车身电子(门控模块、车灯控制、座椅与镜像调节)、传感器与执行器节点、车载网关与工业自动化低速总线设备。其接收器滞后设计改善在噪声环境中的误触发概率,ESD 抗扰能力提高现场装配与维护的可靠性。

四、典型系统设计注意事项

  • 电源去耦:建议在器件电源引脚处安排适当的去耦电容以抑制瞬态干扰。
  • 总线保护:在总线侧可根据系统需求增加浪涌保护与滤波元件,以配合器件的宽电压耐受能力。
  • 休眠策略:利用低静态电流特性设计睡眠/唤醒逻辑,可有效降低整车待机能耗。
  • 布局:SO-8 封装利于短走线布置,应确保差分端与接地良好以降低共模噪声耦合。

五、封装与可靠性

TJA1021T/10/C,118 采用工业常用的 SO-8 小外形封装,便于 SMT 生产与热管理。恩智浦品牌与规范化制造流程保证了器件的批次一致性与长期可用性,适合要求长期稳定运行的车规级或工业级项目。

综上所述,TJA1021T/10/C,118 是一款面向 LIN 总线节点的高可靠性、低功耗、宽电压范围收发器,适合需要在复杂电磁与供电环境下工作的车载和工业通信应用。

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
