TJA1441AT/0Z是恩智浦(NXP)推出的一款高速CAN总线收发器,作为CAN系统的物理层核心器件,负责连接CAN控制器与总线网络,实现逻辑信号与差分总线信号的双向转换。凭借高带宽、宽温适应性等特性,它广泛适配汽车电子、工业自动化等对可靠性要求严苛的场景,是当前高速CAN总线系统的主流选择之一。
作为NXP经典TJA系列的一员,TJA1441AT/0Z定位为高速CAN收发器,针对对数据实时性、传输带宽要求较高的应用设计。NXP作为全球汽车电子与工业控制领域的核心供应商,其TJA系列收发器经过多年市场验证,具备成熟的可靠性与兼容性,TJA1441AT/0Z延续了该系列的技术优势,同时优化了高速传输性能,适配新一代车载与工业系统的需求。
支持最高5Mbps数据速率,属于高速CAN(HS-CAN)范畴(通常高速CAN速率≥1Mbps),可满足汽车ADAS系统的多传感器数据融合(如毫米波雷达、摄像头的实时数据传输)、工业机器人的控制指令交互等高带宽需求,相比低速CAN(≤125kbps)的传输效率提升超40倍。
实现CAN控制器的TTL/CMOS逻辑电平与CAN总线的差分电平(CAN_H/CAN_L)转换,同时具备信号放大、噪声抑制功能,确保总线信号在1km以内的长距离传输中保持稳定,减少误码率。
采用8-SOIC封装(小外形集成电路),尺寸为0.154英寸(约3.90mm宽),属于表面贴装类型,体积紧凑,适合PCB空间有限的场景(如汽车仪表盘ECU、小型工业控制器)。
典型引脚配置包括:VCC(供电)、GND(地)、TXD(发送数据输入)、RXD(接收数据输出)、CAN_H/CAN_L(总线接口)、S(待机/正常模式选择)、NC(空脚),引脚功能清晰,便于电路设计与焊接,可兼容现有CAN系统的硬件布局。
TJA1441AT/0Z的特性使其适配多类高可靠性场景:
支持**-40℃~+150℃**的工作温度,覆盖汽车级宽温要求,可稳定工作于发动机舱高温环境(最高可达125℃)或低温地区(如北方冬季),无需额外温度补偿,降低系统设计复杂度。
具备CAN总线故障保护功能(如CAN_H/CAN_L短路、过流保护),同时差分传输天然抗共模干扰,符合汽车电子EMC(电磁兼容性)标准,减少对外辐射干扰,提升系统抗外界电磁干扰能力(如车载系统抗点火干扰)。
采用NXP成熟的半导体工艺,经过汽车级可靠性测试(如高低温循环、振动测试、湿度测试),可确保在严苛环境下长期稳定工作(典型寿命超10年),降低系统维护成本。
综上,TJA1441AT/0Z凭借高速传输、宽温适应性、紧凑封装等特性,成为汽车电子与工业自动化领域高速CAN总线系统的理想选择,可有效提升系统的传输效率与可靠性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
