HMT1044T CAN收发器产品概述

HMT1044T是捷茂微(GATEMODE)推出的一款工业级高速CAN收发器,专为需要高可靠性、低功耗及宽温适应性的通信场景设计。其核心参数覆盖工业自动化、汽车电子等领域的主流需求,兼具高速通信与节能特性,是总线通信节点的理想选择。

一、产品核心定位与优势

HMT1044T的设计聚焦工业级可靠性与场景适配性,核心优势体现在三个维度:

  1. 高速通信能力:支持5Mbps数据速率,可兼容CAN FD协议的高速传输需求,满足工业现场对实时数据交互的要求;
  2. 宽温宽压适应性:工作温度覆盖-40℃+125℃(工业级标准),工作电压兼容4.5V5.5V(常见MCU/电源的5V±10%范围),适配极端环境;
  3. 低功耗设计:静态电流仅5uA,通信时工作电流70mA,平衡性能与节能,适合电池供电或长期待机的节点(如远程监测设备)。

二、关键技术参数详解

1. 通信性能

  • 数据速率:5Mbps(典型值),支持CAN 2.0A/B协议,可兼容CAN FD的高速传输模式;
  • 差分传输:CAN_H与CAN_L采用差分信号传输,抗电磁干扰(EMI)能力强,适合工业现场复杂电磁环境;
  • 总线负载:可支持最多110个节点(CAN总线标准负载能力),满足多设备组网需求。

2. 电源特性

  • 工作电压:4.5V~5.5V(覆盖汽车电子、工业控制的常用供电范围,无需额外电平转换);
  • 工作电流:70mA(通信时典型值,低功耗设计减少电源负担);
  • 静态电流:5uA(休眠模式典型值),支持硬件/软件唤醒,节能效果显著。

3. 环境适应性

  • 工作温度:-40℃~+125℃(工业级宽温,可在户外、高温车间等极端场景稳定运行);
  • 存储温度:-55℃~+150℃(满足运输/存储的极端条件);
  • 湿度范围:5%~95%(无凝结),适配潮湿环境。

4. 封装与引脚

  • 封装形式:SOP-8(贴片式封装,尺寸小、易焊接,适合高密度PCB设计);
  • 引脚定义:符合CAN收发器通用规范(含VCC、GND、CAN_H、CAN_L、TX、RX、休眠控制脚、空脚),无需特殊适配即可替换同类产品。

三、典型应用场景

HMT1044T的参数特性使其适配多领域场景,核心应用包括:

  1. 工业自动化:PLC、传感器节点、机器人控制系统(宽温+高速满足现场实时交互);
  2. 汽车电子:车身控制系统、动力总成(如发动机ECU)、车载诊断系统(OBD)(5V兼容汽车电源,宽温适配车载环境);
  3. 智能交通:交通信号控制器、车载终端、道路监测设备(抗干扰+低功耗适合户外长期运行);
  4. 物联网边缘节点:远程环境监测(温湿度、水位)、智能农业传感器(低静态电流延长电池寿命);
  5. 医疗设备:小型诊断仪器、监护设备(可靠性+宽温满足医疗场景稳定性要求)。

四、可靠性与应用设计建议

1. 可靠性保障

  • ESD防护:支持±15kV接触放电、±8kV空气放电(符合IEC 61000-4-2标准),避免静电损坏;
  • 过温保护:内置过温检测机制,温度过高时自动关断输出,保护芯片及总线;
  • EMC兼容性:符合EN 55032(工业EMC标准),减少对周边设备的干扰。

2. 设计注意事项

  • 电源滤波:VCC引脚并联10uF电解电容+0.1uF陶瓷电容,过滤电源噪声;
  • 终端电阻:CAN总线两端焊接120Ω终端电阻(匹配总线阻抗,减少信号反射);
  • 休眠唤醒:休眠控制脚(S脚)接MCU GPIO实现硬件唤醒,静态模式下需确保TX/RX电平稳定;
  • 布线规范:CAN_H与CAN_L平行布线、长度一致,远离高速数字信号线,减少串扰;
  • 静电防护:CAN总线引脚外接TVS管(如SMBJ6.5),增强ESD防护能力。

五、总结

HMT1044T作为捷茂微的工业级CAN收发器,以高速、宽温、低功耗为核心亮点,适配多领域通信需求。其SOP-8封装易集成,可靠性符合工业标准,是替代传统CAN收发器的高性价比选择,尤其适合对成本敏感且要求性能稳定的场景。

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
