TJA1057GT/1Z 产品概述

一、产品简介

TJA1057GT/1Z 是恩智浦(NXP)面向汽车与工业控制领域的单通道 CAN-FD 收发器,采用 SOIC-8 封装,支持 CAN 数据帧的传统位速与增强数据速(CAN-FD)。器件为单通道、半双工收发结构,兼顾高可靠性与工业级耐受性,适用于严苛环境下的车载网络节点与嵌入式控制器。

二、核心参数

  • 类型:CAN-FD 收发器(单通道、半双工)
  • 数据速率:最高 5 Mbps(数据相位)
  • 工作电压:4.75 V ~ 5.25 V
  • 工作电流(典型):约 70 mA(活动)
  • 静态/待机电流:约 1.2 mA
  • 工作温度:-40 ℃ ~ +150 ℃(高温等级,适合严苛环境)
  • 封装:SOIC-8(8 引脚)
  • 品牌:NXP(恩智浦)

三、主要特性与功能

  • 支持 CAN-FD 协议的数据相位高数据速率能力,满足 5 Mbps 等高速需求。
  • 宽电源容差及稳健的电源管理,适配 5V 汽车电源系统。
  • 低静态电流的待机模式,适合低功耗/睡眠态网络节点。
  • 工业/汽车级温度范围(-40 ℃ 至 +150 ℃),适合高温环境长期运行。
  • 常见保护功能(短路保护、热关断、总线故障检测/容错),提高系统鲁棒性(建议参考官方数据手册确认具体保护机制和极限值)。
  • SOIC-8 标准封装,便于直接替换与波形兼容的 PCB 设计。

四、典型应用场景

  • 汽车车身控制单元(BCM)、车身网关与车载传感器节点。
  • 工业自动化控制网络、现场总线接口模块。
  • 电机控制、网关、数据记录器等需要高可靠通信与高温耐受的嵌入式设备。

五、设计与布局建议

  • 在 VCC 端配备 0.1 µF 陶瓷旁路电容,并靠近器件引脚布局以抑制瞬态干扰。
  • CAN_H / CAN_L 差分对走线长度应匹配,差分阻抗控制在 120 Ω 匹配终端,推荐在总线两端各并联 120 Ω 终端电阻。
  • 在布线时将终端电阻靠近收发器放置,以减少反射与 EMI。必要时在差分总线上加入共模电感以抑制辐射。
  • 器件具有保护功能,但仍建议在设计中考虑外部浪涌保护与 TVS 二极管以应对高能瞬态事件。
  • 对于热设计,注意封装散热路径与 PCB 铜箔面积,避免长期高电流导致温升过高。

六、采购与兼容性说明

TJA1057GT/1Z 为 NXP 正式型号,SOIC-8 封装便于替换同类标准封装收发器。具体管脚功能、电气特性曲线、保护逻辑及推荐典型电路请以 NXP 官方数据手册为准;在批量导入前建议索取样片并进行实际信号完整性与热性能验证。

七、总结

TJA1057GT/1Z 以其支持 CAN-FD(最高 5 Mbps)、窄电压工作范围(4.75–5.25 V)、低待机电流(1.2 mA)及宽工作温度(-40 ℃ 至 +150 ℃)等特性,适合车载与工业级通信节点。合理的 PCB 布局与必要的外围保护电路能进一步提升系统可靠性,建议在设计初期结合官方资料进行详细验证与测试。

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
