TJA1044GT/1 产品概述
一、产品概况
TJA1044GT/1 是恩智浦（NXP）推出的一款高性能 CAN 收发器，面向汽车及工业级控制网络设计。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，适配标准高速 CAN 总线，兼顾低功耗待机与稳健的工作保护特性。封装为常用的 SOIC-8，便于 PCB 布局与替换。
二、主要参数与特性
- 数据速率：最高 5 Mbps，满足高速 CAN 通信需求。
- 工作电压：4.5V ~ 5.5V，适配 5V 系统设计。
- 工作电流：典型工作电流约 60 mA（总线活动状态下）。
- 静态/待机电流：低至 15 μA，利于节能与休眠管理。
- 工作温度：-40 ℃ ~ +150 ℃，覆盖严苛环境与汽车级温度要求。
- 封装：SOIC-8，常见表贴封装，便于制造与维护。
三、功能与设计亮点
TJA1044GT/1 作为 CAN 收发器，承担 CAN 控制器与差分总线之间的电平与隔离转换。器件通常具备以下功能：
- 差分驱动与接收，保证总线上的差分信号完整性；
- 低功耗待机模式，实现节点睡眠与快速唤醒；
- 总线故障保护（短路、开路及振铃抑制）与热关断保护，提升系统可靠性；
- 与微控制器的 TXD/RXD 接口兼容，易于软件层集成与诊断。
四、典型应用场景
- 车身电子（BCM、车门模块、车灯控制等）；
- 发动机与底盘控制单元（ECU 通信互联）；
- 工业自动化网络与传感器节点；
- 总线诊断工具、数据记录仪与网关设备。
五、封装、选型与可靠性建议
- 推荐封装：SOIC-8（便于手工与批量焊接），留意引脚排列与散热走线；
- 电源旁路：在 VCC 处建议使用适当的去耦电容，抑制瞬态干扰；
- PCB 布局：CANH/CANL 走差分线、靠近收发器引出并留出隔离回路，减少干扰；
- 温度与热管理：器件支持高温工作，但在高发热场景下应确保散热与良好通风。
总结：TJA1044GT/1 以其 5 Mbps 的高速能力、宽电压范围、极低待机电流与宽温度等级，适合需要高可靠性和低功耗的汽车及工业 CAN 网络设计。设计时结合合适的 PCB 布局与电源滤波，可充分发挥其性能并提升系统稳定性。
Request for quote

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.
