HMT1051T/3是GATEMODE(捷茂微)推出的高速CAN收发器,专为汽车电子、工业自动化等对通信速率、环境适应性要求严苛的场景设计。核心特性聚焦“高速通信+宽温宽压+低功耗”三大维度,具体包括:支持最高5Mbps数据速率、-40℃+125℃工业级宽温范围、4.5V5.5V宽电源电压、5mA低静态电流,以及SOP8标准贴片封装,可直接兼容主流PCB设计。
5Mbps数据速率是HMT1051T/3的核心亮点——当前主流CAN FD协议支持最高8Mbps速率,5Mbps可覆盖90%以上的工业/汽车高速通信场景(如汽车动力系统实时数据传输、工业机器人运动控制指令)。相比传统1Mbps速率的CAN收发器,传输效率提升4倍,大幅缩短指令响应时间,避免通信瓶颈。
4.5V5.5V的电源范围,兼容汽车12V系统经DC-DC转换后的5V电源(汽车电源波动通常为9V16V,转换后5V±10%即此范围),也适配工业24V系统的5V输出。5mA静态电流在待机/低负载状态下显著降低功耗,适合电池供电的车载终端等续航敏感场景。
-40℃~+125℃的工作温度,接近AEC-Q100车规级标准,可适应汽车发动机舱高温(夏季可达100℃以上)、工业现场低温严寒(北方冬季户外设备),以及极端温差变化,避免温度导致的通信中断或器件损坏。
SOP8贴片封装体积紧凑(约5.2mm×6.4mm),适合PCB布局紧凑的设备(如汽车ECU、小型PLC)。引脚间距1.27mm,焊接工艺成熟(兼容回流焊、波峰焊),批量生产良率高,无需额外定制封装。
HMT1051T/3的参数特性使其可广泛应用于以下领域:
相比进口品牌(如TI SN65HVD230、NXP TJA1050),HMT1051T/3具备以下优势:
为确保通信稳定,设计时需注意:
HMT1051T/3作为GATEMODE推出的高速CAN收发器,凭借高速通信、宽温宽压、低功耗等特性,可有效满足汽车电子、工业自动化等领域的通信需求,是进口同类产品的高性价比替代方案。
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.
