TJA1443AT/0Z 产品概述
一、产品简介
TJA1443AT/0Z 是恩智浦（NXP）推出的一款高性能高速 CAN 收发器，面向汽车与工业级网络应用，支持高达 5 Mbps 的数据速率。器件工作电压范围为 4.5 V ～ 5.5 V，工作温度范围宽（-40 ℃ ～ +150 ℃），封装为 14-SOIC（0.154", 3.90 mm 宽），适合苛刻环境下的长期可靠工作。
二、主要功能特性
- 支持高速 CAN 总线，最高数据速率 5 Mbps
- 超低待机静态电流：2 μA（低功耗待机模式）
- 多种工作模式：正常模式、静默（Silent）模式、低功耗模式、使能/禁能以及局部唤醒/唤醒功能
- 保护与可靠性：短路保护、热关断（热关机）保护、欠压检测保护、ESD 抗扰度
- 传输安全：TXD 占优超时（防止 TXD 卡位导致总线持续占优）
三、电气与封装信息
- 工作电压：4.5 V ～ 5.5 V
- 工作温度：-40 ℃ ～ +150 ℃
- 静态电流（低功耗/待机）：约 2 μA
- 封装：14-SOIC（0.154"，宽度 3.90 mm）
- 品牌：NXP（恩智浦）型号：TJA1443AT/0Z
四、典型应用场景
- 汽车域控制器（车身电子、车身网关、车载诊断）
- 高速 CAN 总线网关与收发模块
- 工业控制网络与传感器节点
- 需要低功耗待机与唤醒功能的分布式系统
五、设计注意事项与建议
- 在 VCC 引脚附近放置合适值的旁路电容（如 0.1 μF 与 1 μF），以抑制瞬态噪声。
- CANH/CANL 终端电阻（典型 120 Ω）应靠近收发器布置，必要时配合共模电感与滤波网络以提高 EMC 性能。
- 为了利用器件的保护功能，建议在布线时预留热关断与短路容差，避免长期过流运行。
- 对于需要局部唤醒的系统，合理使用器件的唤醒和使能引脚，避免误唤醒并保证低功耗性能。
六、结论
TJA1443AT/0Z 结合高速数据能力、极低待机功耗和多重硬件保护，非常适合要求可靠性与能效并重的汽车与工业 CAN 网络应用。使用时注意良好 PCB 布局与电源滤波设计，可发挥器件在耐久性与抗扰度方面的优势。若需详细电气参数与时序，请参考恩智浦官方数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
