TJA1145AT/FD/0Z 产品概述

一、概览

TJA1145AT/FD/0Z 是恩智浦(NXP)推出的一款单通道 CAN-FD 收发器(IC TRANSCEIVER FULL 1/1),面向要求高速与高可靠性的车载与工业网络物理层应用。器件支持 CAN-FD 数据速率至 5 Mbps,工作电压范围为 4.5 V 至 5.5 V,适用于以 5V 供电为主的系统。其工作温度范围宽(-40℃ 至 +150℃),能够满足严苛环境下的长期运行要求。

二、主要电气参数

  • 类型:CAN-FD 收发器(单通道,1/1)
  • 最大数据速率:5 Mbps(CAN-FD)
  • 工作电压(VCC):4.5 V ~ 5.5 V
  • 工作电流:65 mA(典型/最大工作态,应参考数据手册)
  • 静态电流(待机/静止):68 μA(低功耗态利于节能与微唤醒设计)
  • 工作温度:-40℃ ~ +150℃
  • 封装:SOP-14
  • 品牌:NXP(恩智浦)

三、功能与应用场景

TJA1145AT/FD/0Z 提供 CAN-FD 物理层传输所需的差分驱动与接收功能,适合车载网络(如域控制器、车身电子控制单元、车载网关)及要求高实时性的工业控制网络。典型应用包括:

  • 汽车控制网络(ADAS、动力及车身控制)
  • 车载网关与 ECU 之间的高速通信链路
  • 工业总线系统中需要更高带宽的节点
  • 严苛环境中的嵌入式网络接口

四、封装与机械特性

该器件采用 SOP-14 封装,利于传统 PCB 组装流程与自动贴装。SOP-14 在空间与散热方面达到平衡,适合车规应用的可靠焊接和长期稳定性要求。由于器件额定温度上限达 +150℃,在热管理和 PCB 设计中仍应考虑功耗散热路径和周围器件的热影响。

五、设计注意事项

  • 电源滤波与去耦:建议在 VCC 近端放置低 ESR 电容(如 0.1 μF + 1 μF 的组合)以保证瞬态响应与抑制噪声;同时考虑 CAN 总线上的共模干扰抑制。
  • 布线与阻抗匹配:CAN 差分对需保持恒定差分阻抗并尽量短直,避免不必要的分支;终端电阻应按总线拓扑正确配置。
  • 低功耗模式利用:静态电流仅 68 μA,可用于待机或休眠态节能设计,唤醒路径与控制信号逻辑应在系统设计中明确。
  • 热设计:持续 65 mA 的工作电流在高温环境下会产生热量,建议评估 PCB 散热、器件间距和外壳散热条件,必要时采用散热优化方案。
  • 数据手册确认:本概述基于关键参数,实际应用前应参考恩智浦官方数据手册以确认引脚排列、电气时序、保护特性(如短路保护、ESD、失能/复位逻辑)以及封装尺寸与焊接规范。

六、选型建议与优势

TJA1145AT/FD/0Z 的优势在于针对 CAN-FD 高速通信的支持、宽温特性与较低待机电流,适合需要在恶劣环境中长期运行且对带宽有较高要求的系统。若项目要求 5V 供电、SOP-14 封装兼顾产线适配性、并重视待机能耗与高温可靠性,该器件是值得优先考虑的物理层收发器选项。最终选型应综合系统总线拓扑、EMC 要求及热/机械约束,配合数据手册进行验证与样片测试。

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
