CA-IF1051S 产品概述

一、产品简介

CA-IF1051S 是川土微(Chipanalog)推出的一款高可靠性 CAN 总线收发器,面向汽车和工业现场总线应用。器件支持高达 2 Mbps 的差分数据传输,工作电压 4.5 V 至 5.5 V,工作电流典型值为 80 mA,工作温度范围宽至 -55 ℃ 至 +150 ℃,并在 CAN 总线端提供高达 ±58 V 的故障保护,显著提升系统抗干扰与抗故障能力。

二、主要特性

  • 支持差分数据速率:最高 2 Mbps,满足高速 CAN 通信需求。
  • 电源要求:单电源 4.5 V ~ 5.5 V 供电,便于与 5 V 逻辑系统接口。
  • 低功耗工作电流:典型值 80 mA(实际视工作条件而定)。
  • 宽温度范围:-55 ℃ ~ +150 ℃,适应苛刻环境与高温作业场景。
  • 强化故障保护:CAN_H/CAN_L 对地或对地电压出现异常时,器件可承受 ±58 V,提升系统安全性。
  • 封装形式:标准 SOIC-8,利于自动化贴装和替换维护。

三、目标应用场景

  • 汽车电子:车身控制模块、网关、动力总成控制单元(ECU)等需可靠总线通信的场合。
  • 工业自动化:PLC、驱动器、远程 I/O、现场总线网关等。
  • 轨道交通与工程机械:高温、强干扰环境下的总线扩展与诊断。
  • 通用嵌入式系统:需要抗短路、碰撞故障保护的差分通信接口场合。

四、封装与引脚说明

CA-IF1051S 提供 SOIC-8 封装形式,兼容常见的 PCB 布局与自动贴片工艺。引脚通常包括 VCC、GND、TXD、RXD、CAN_H、CAN_L 以及若干故障/配置引脚,便于与 MCU 或 CAN 控制器直接对接(详细引脚与功能请参照器件数据手册)。

五、设计与使用建议

  • 总线终端:典型差分总线两端各应并联 120 Ω 终端电阻,保证信号完整性与阻抗匹配。
  • 散热与布局:尽量将器件靠近总线连接器并保持良好接地,关键信号线短且对称,减少共模干扰。
  • 输入滤波与保护:在高干扰环境中可配合共模电感与 TVS 等器件进一步提升抗扰度。
  • 测试与可靠性:在高温和故障注入条件下进行系统级测试,验证 ±58 V 故障保护在实际应用中的表现。

CA-IF1051S 以其宽工作温度、高抗故障能力和标准封装,为需要高度可靠 CAN 通信的系统提供稳健的物理层解决方案。欲获取详细电气参数、典型波形和引脚定义,请参考芯片数据手册或联系川土微技术支持。

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
