CA-IF1051HS 产品概述

一、产品简介

CA-IF1051HS 是川土微(Chipanalog)推出的一款高可靠性CAN收发器,面向汽车与工业现场总线应用设计。器件在4.5V~5.5V供电范围内工作,支持最高2Mbps的数据传输速率,并具备高强度的故障保护能力(±70V)。器件采用SOIC-8封装,适合标准PCB装配与量产。

二、主要技术参数

  • 类型:CAN收发器
  • 数据速率:最高 2 Mbps
  • 工作电压:4.5 V ~ 5.5 V
  • 工作电流:典型 80 mA
  • 静态电流:2.5 mA
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 故障保护:CAN总线端口 ±70 V
  • 品牌:Chipanalog(川土微)
  • 封装:SOIC-8

三、关键特性

  • 宽温工作:支持-55 ℃ 到 +150 ℃的极宽温区,满足汽车和严苛工业环境的长期可靠性要求。
  • 高速通讯:最大2Mbps的数据速率可满足常见的高速CAN或车辆内部控制网络需求。
  • 强抗故障能力:双向总线端口可承受±70V的瞬态或故障电压,提升系统在短路、电源反接或电磁干扰下的存活能力。
  • 低静态功耗:待机/静态状态下电流仅约2.5mA,利于系统的节能与休眠管理。
  • 标准封装:SOIC-8 便于在现有的PCB和SMT工艺中替换与集成。

四、典型应用场景

  • 车载CAN网络(车身控制、动力总成、网关模块等)
  • 工业自动化现场总线与设备互联
  • 重型机械与工程车辆的控制与监测系统
  • 需要高抗干扰与宽温的嵌入式通信节点

五、封装与引脚建议

  • 封装:SOIC-8,标准引脚排列,便于替代与维修。
  • 推荐在VCC旁并联0.1µF与1µF的去耦电容,靠近器件放置以减少电源噪声。
  • 总线端建议在两端各并联120Ω终端电阻以保证差分阻抗匹配。必要时在终端处加入TVS器件作为二次保护。

六、使用建议与注意事项

  • 供电电压应严格控制在4.5V~5.5V范围内,避免长期偏离以确保参数稳定与寿命。
  • 在高电流工作场景下(例如频繁发送大帧),注意PCB散热设计,并留出热流/散热通路。
  • 如系统存在强电磁干扰或接地回路问题,建议在器件周边做好信号地与电源地分离与滤波设计。
  • 在设计冗余或保护策略时,可结合器件的±70V故障保护特性,简化外部保护元件配置,但对极端故障场景仍建议做级联保护。

七、可靠性与测试建议

  • 在产品验证阶段,进行温度循环、长期高低温老化以及总线短路/电压尖峰注入测试,以验证在-55 ℃~+150 ℃和±70V故障条件下的稳定性。
  • 关注器件的热阻与PCB热管理,必要时在关键点做热成像验证。

八、总结

CA-IF1051HS 为面向严苛环境的CAN收发器,凭借±70V的强故障保护、宽温范围与2Mbps的高速能力,适合汽车级与工业级应用场景。其SOIC-8封装与较低静态功耗使其在空间受限且需长时间在线的系统中具有良好实用性。设计时按推荐去耦、终端匹配与热管理方案实施,可快速构建稳定可靠的CAN节点。

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
