  • 超低静态电流(2uA典型值),支持低功耗待机;
  • 工业级宽温范围(-40℃~+125℃),满足 harsh环境应用;
  • SOP-8L表面贴装封装,便于PCB设计与批量生产。

二、关键参数详解

1. 通信性能

HMT234T支持1Mbps高速通信,差分传输机制(CAN_H/CAN_L)具备强抗干扰能力,可抑制总线噪声,典型传输距离达1km@1Mbps,满足工业/车载总线的长距离通信需求。

2. 电源与功耗

  • 供电范围:3V~3.6V单电源,无需额外电源转换,简化系统设计;
  • 静态电流:2uA(待机模式),适合电池供电的便携设备(如无线传感器节点);
  • 工作电流:600uA(典型值,1Mbps通信时),功耗远低于传统收发器,提升系统能效。

3. 环境适应性

  • 工作温度:-40℃~+125℃工业级宽温,可稳定工作于户外、车载等极端场景;
  • 存储温度:-55℃~+150℃,满足器件长期存储可靠性要求。

三、封装与引脚功能

HMT234T采用SOP-8L 封装(8引脚表面贴装),引脚布局清晰,兼容主流PCB规范,核心引脚功能如下:

  1. VCC:电源输入(3V~3.6V);
  2. GND:地;
  3. TXD:CAN发送数据输入(来自MCU);
  4. RXD:CAN接收数据输出(至MCU);
  5. CAN_H:CAN总线高电平端;
  6. CAN_L:CAN总线低电平端;
  7. NC:空脚(无连接);
  8. S:睡眠控制引脚(低电平触发待机模式)。

四、典型应用场景

HMT234T的参数特性覆盖多领域需求:

  1. 工业自动化:PLC、远程IO模块、传感器网络(宽温适应车间 harsh环境);
  2. 汽车电子:车身控制单元(BCM)、OBD诊断系统、CAN总线节点(1Mbps匹配车载通信);
  3. 电池供电设备:便携工业检测仪、无线传感器节点(2uA静态电流延长电池寿命);
  4. 智能家居/楼宇自动化:智能网关、安防系统、智能照明(稳定通信+低功耗)。

五、可靠性与设计优势

  • ESD防护:内置±8kV接触放电、±15kV空气放电防护,避免静电损坏;
  • EMI优化:差分传输+低功耗电路,减少电磁干扰,符合EMC标准;
  • RoHS合规:无铅无卤封装,满足环保要求;
  • 睡眠模式:S引脚触发待机,静态电流仅2uA,大幅降低系统待机功耗。

六、品牌与选型建议

GATEMODE(捷茂微)是国内专注汽车级/工业级接口芯片的厂商,产品通过AEC-Q100(车载级)、ISO 9001认证,质量可靠。HMT234T对比同类产品的核心优势:

  • 超低静态电流(2uA),适配电池供电场景;
  • 工业级宽温(-40~125℃),覆盖更多应用;
  • 高性价比,降低系统BOM成本。

若需高速CAN通信、低功耗及宽温适应性,HMT234T是理想选型方案。

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.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
