TJA1057GTKZ 产品概述

一、主要参数概览

TJA1057GTKZ 是恩智浦(NXP)面向汽车与工业高可靠性场景的 CAN 收发器,关键参数如下:

  • 类型:CAN 收发器(半双工/1:1 节点拓扑适用)
  • 最大数据速率:5 Mbps,可满足高速实时通信需求
  • 工作电压:4.5 V ~ 5.5 V(典型 5 V 供电)
  • 工作电流:典型 70 mA(总线活动时)
  • 静态电流(待机/低功耗):约 1.2 mA
  • 工作温度范围:-40 ℃ ~ +150 ℃(适配汽车级高温环境)
  • 封装:HVSON-8-EP(3 x 3 mm,带外露铜焊盘)

二、产品特性与功能说明

  • 高速通信:最高支持 5 Mbps,适合现代车载网络与工业控制中对带宽要求较高的场合。
  • 低功耗待机:待机模式下静态电流仅约 1.2 mA,有助于整车电能管理。
  • 汽车级耐温:-40 ℃ 至 +150 ℃ 的工作温度覆盖了发动机舱等高温环境。
  • 封装优势:HVSON-8-EP 小型化且带热焊盘,利于散热与 PCB 面积优化。
  • 接口与兼容性:典型引脚包括 VCC、GND、TXD、RXD、EN/STB、CAN_H、CAN_L,便于与微控制器和网关集成。
    (注:具体保护功能、诊断功能和引脚电气特性请以原厂数据手册为准。)

三、典型应用场景

  • 汽车车身与动力系统通信总线(ECU 间高速交换数据)
  • 车载网关与域控制器(需要高耐温与高带宽)
  • 工业自动化控制网络(实时控制与诊断数据传输)
  • 运输与商用车辆电子系统(耐环境恶劣、长期可靠性要求高)

四、封装与 PCB 设计建议

  • 外露焊盘(EP)应连至器件地并通过多盲孔或过孔接地,以优化散热与可靠性。
  • 在 VCC 与 GND 之间靠近器件放置 0.1 μF 陶瓷去耦电容及一个较大容量的旁路电容,减小瞬态电流影响。
  • CAN_H、CAN_L 总线端推荐在靠近收发器处使用 120 Ω 终端电阻;必要时加 TVS 抑制器以增强浪涌/浪涌保护。
  • 布线注意差分对长度匹配与阻抗控制,避免与噪声源平行走线以降低 EMI。

五、热性能与可靠性注意事项

  • 器件在高温工作时应充分考虑 PCB 散热能力与周边热源影响;外露焊盘是主要散热通道,建议增大铜皮面积并连至内层散热层。
  • 长期在高电流或高占空比工作下,需验证器件结温不超过规定极限;设计时预留安全裕量。
  • 在系统级验证中进行 ESD、短路、浪涌与温度循环测试,确保满足整车/工业认证要求。

六、选型与工程注意

  • 若系统需要更低待机电流或不同工作电压范围,请对比同系列或同厂商其它型号。
  • 在量产前务必参考 NXP 官方数据手册与应用说明,确认所有极限值、启动时序及容差指标。
  • 对于关键安全/功能节点,建议预留冗余与诊断机制,并在 PCB 层面实施适当防护以提高系统鲁棒性。

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
