TJA1043TKY 产品概述

TJA1043TKY 是恩智浦(NXP)面向汽车总线应用的 CAN 收发器,属于单通道高可靠性器件。该器件以 4.5V–5.5V 的工作电压供电,支持高达 5 Mbps 的数据速率,静态电流仅 2 µA,工作电流典型值约 65 mA,并能在 -40℃ 至 +150℃ 的宽温区间内稳定工作。器件以 HVSON-14-EP(3 × 4.5 mm)小封装提供,适合空间受限且需高温可靠性的车载电子设计。

一、主要特性

  • 单通道 CAN 收发功能,适配标准 CAN 协议链路。
  • 支持最高 5 Mbps 数据速率,满足高速数据传输需求。
  • 宽工作电压:4.5V ~ 5.5V,兼容典型车载 5V 电源系统。
  • 低静态电流:2 µA(待机模式),利于低功耗设计。
  • 典型工作电流约 65 mA(正常收发),性能稳定。
  • 宽温度范围:-40℃ ~ +150℃,适合发动机舱与车载高温环境。
  • 紧凑 HVSON-14-EP(3×4.5 mm)封装,带散热焊盘,便于 PCB 布局与散热。

二、典型电气参数(摘要)

  • 供电电压:4.5 V 至 5.5 V
  • 数据速率:最高 5 Mbps
  • 工作电流:约 65 mA(典型,取决于工作状态)
  • 待机/静态电流:约 2 µA
  • 工作温度:-40℃ 至 +150℃

(具体的极限参数、电压容限、收发阈值与时序请参阅官方数据手册以获得完整规范与测试条件。)

三、封装与引脚信息

器件采用 HVSON-14-EP 小型扁平封装(尺寸 3 × 4.5 mm),带底部散热焊盘(EP)。该封装利于热量传导和可靠焊接,适用于自动化贴装与车规级制造工艺。设计时建议在 PCB 底部与 EP 相对应位置开铜并做过孔或散热处理,以提升热性能与机械可靠性。

四、典型应用场景

  • 车身电子控制单元(BCM)、车门模块与车灯控制
  • 动力传动与底盘控制的诊断与通信链路
  • 车载网关、传感器聚合器与域控制器的 CAN 总线接口
  • 工业自动化与需要宽温、长寿命的嵌入式 CAN 通信系统

五、设计与使用建议

  • 电源滤波:在 VCC 端加入合适的去耦电容(例如 100 nF 与 1 µF 组合),靠近器件引脚布置以抑制噪声。
  • 终端匹配:按 CAN 规范在总线两端加入 120 Ω 终端电阻,保证信号完整性与反射抑制。
  • 接地与散热:合理铺铜并确保底部散热焊盘焊接良好,减小热阻并提升长期可靠性。
  • EMC 与保护:在高噪声环境中,可在 CAN_L/CAN_H 上增加共模扼流圈、TVS 二极管等以提高抗干扰与过压保护能力。
  • 软硬件管理:利用器件待机特性控制静态电流,在不通信时进入低功耗状态以节能。

六、质量与可靠性建议

针对车规级应用,建议在样机阶段验证器件在高温、热循环、ESD 与浪涌等应力下的行为,并在生产测试中包含对 CAN 总线收发功能、休眠唤醒及功耗的检验。与供应商确认长期供应与质量管理(PPAP、APQP)流程,以确保量产可靠性。

总结:TJA1043TKY 以其高温能力、低静态功耗与较高数据速率,适合对空间、热与电气性能有较高要求的车载 CAN 应用。欲获得完整电气特性、引脚定义与典型应用电路,请参阅恩智浦官方数据手册并结合系统级 EMC 与热设计进行验证。

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
