HMT1050T 产品概述

HMT1050T 是捷茂微(GATEMODE)推出的一款单通道CAN总线收发器,采用SOP-8封装,针对汽车级与工业级网络通信场景设计。器件支持最高1 Mbps的数据速率,工作电压为5 V,工作温度范围宽达-40℃到+125℃,具备多种保护与节能功能,适合在严苛环境下实现稳定的CAN侧物理层连接。

一、主要规格概览

  • 类型:CAN 收发器(单通道)
  • 数据速率:最高 1 Mbps
  • 工作电压:5 V
  • 工作电流(活动):约 75 mA
  • 静态电流(休眠/空闲):约 5 mA
  • 工作温度:-40℃ 至 +125℃
  • 封装:SOP-8
  • 主要功能:静默模式、热关断保护、ESD 保护、TXD 占优超时检测、总线故障保护

二、功能与保护特性解析

HMT1050T 集成了多项实用保护与控制功能:

  • 静默模式(Silent Mode):允许节点在不驱动总线的情况下监听总线,便于诊断、固件升级或从属节点监听,减少对线路的干扰。
  • TXD 占优超时(TXD Dominant Timeout):当驱动端意外长时间保持显性(dominant)状态时,超时机制可释放总线,避免单点失效导致总线挂死。
  • 热关断(Thermal Shutdown):在器件过热时自动切断驱动,防止因短路或高耗流导致损坏,提升系统安全性。
  • 总线故障保护:对短路至电源、接地或高电压脉冲提供鲁棒性,适合工业与汽车等恶劣环境。
  • ESD 保护:门级静电防护,增强现场装配与使用中的可靠性。

三、典型应用场景

  • 汽车电子:车身控制模块、仪表盘、车门控制器、智能网关等需要工业级温度与可靠性的场合。
  • 工业自动化:现场总线节点、PLC 外围模块、传感器网络等。
  • 运输与重型机械:恶劣电磁环境与高电压脉冲风险下的通信解决方案。
  • 诊断与测试设备:需要监听(静默)功能的现场诊断工具与数据记录器。

四、设计集成建议

  • 电源旁路:VCC 与 GND 之间应靠近器件放置 0.1 μF 陶瓷电容进行去耦,抑制瞬态噪声。
  • 总线终端:在网络两端使用 120 Ω 差分终端电阻;必要时在本端并联防浪涌TVS 和共模电感以提高抗扰度。
  • 布线注意:CAN_H/CAN_L 差分对保持等长,远离高频开关电源与大电流走线;GND 返回路径短且粗。
  • 故障检测与复位:利用器件的 TXD 超时与热关断信号配合上层 MCU 做故障记录与恢复策略。

五、选型理由与优势

HMT1050T 在5V工作域内提供了兼顾性能与可靠性的CAN收发能力:1 Mbps 的速率满足高带宽需求;-40℃~+125℃的温度范围和多重保护机制使器件适合汽车与工业级应用;SOP-8 封装便于现有生产线替换与布局。对于需要静默监听、总线健壮性的系统,HMT1050T 是一款性价比高且稳定的解决方案。

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
