TJA1448BT/0Z 产品概述

一、产品简介

TJA1448BT/0Z 是恩智浦(NXP)推出的一款高速 CAN 收发器,用于车用或工业环境下的差分总线通信。该器件支持高达 5 Mbps 的数据速率,工作电压范围为 4.5V 至 5.5V,工作温度覆盖 -40℃ 到 +150℃,适合在严苛环境中实现可靠的 CAN 数据链路。

二、主要特性

  • 支持高速 CAN 通信,数据速率最高 5 Mbps,满足实时数据交换需求。
  • 宽电压工作范围:4.5V–5.5V,适配车载 5V 电源总线。
  • 宽温度范围:-40℃ 至 +150℃,适用于高温/严寒工况。
  • 常见的可靠性与保护特性(差分收发、总线短路容错、瞬态干扰抑制及热保护等)有利于提升整车/系统稳定性。
  • 品牌与封装:NXP(恩智浦),14-SOIC(0.154",3.90mm 宽)封装,便于 PCB 布局与自动贴装。

三、电气与环境参数(概要)

  • 数据速率:5 Mbps(最高)
  • 工作电压:4.5V ~ 5.5V
  • 工作温度:-40℃ ~ +150℃
    这些参数确保在典型车载总线及工业现场总线环境中均能稳定工作,兼顾噪声抑制与长期可靠性。

四、封装与安装

14-SOIC 封装(0.154",3.90 mm 宽),引脚排列适合常见的微控制器与收发器布局。封装尺寸利于散热与机械强度,便于量产贴片和焊接工艺控制。

五、典型应用场景

  • 车载 CAN 总线节点(发动机控制、车身控制单元、车载网关)
  • 工业自动化与现场总线接口
  • 船舶与轨道交通的通信接口(需符合系统认证要求)
  • 需耐高温或高电压扰动的嵌入式通信模块

六、设计与可靠性要点

在使用时应关注电源去耦、共模干扰抑制以及总线防护措施(瞬态电压抑制器、隔离/滤波等)。针对高温应用,需考虑 PCB 散热设计与长期热应力影响,保证焊点及封装可靠性。建议参考器件数据手册进行典型应用电路与外部保护元件的选型。

七、采购与替代建议

作为 NXP 系列高速 CAN 收发器的一员,TJA1448BT/0Z 在车规与工业应用中具有良好兼容性。如需替代或比较,可在同类车规级 CAN 收发器中对比数据速率、工作温度、保护特性和封装尺寸,从而选择更契合系统需求的型号。

如需更详细的电气参数、引脚定义或参考电路,请提供是否需要数据手册或具体应用场景,以便进一步补充。

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
