SIT1051AT 产品概述

一、产品简介

SIT1051AT 是芯力特(SIT)推出的一款 CAN-FD 总线收发器,面向汽车及工业级高可靠性通信场景。该器件支持高达 5 Mbps 的数据速率,工作电压范围为 4.5V 至 5.5V,工作温度范围宽至 -40℃~+150℃,采用 SOP-8 封装,便于标准化 PCB 装配与批量生产。

二、主要性能特性

  • 支持 CAN-FD 通信速率,可满足高速数据交换需求。
  • 5 Mbps 的最大数据传输能力,适用于车载子系统和高速工业总线。
  • 宽电压工作范围 4.5V~5.5V,兼容常见 5V 系统供电。
  • 极宽的工作温度 -40℃~+150℃,适配高温环境和动力舱附近应用。
  • SOP-8 封装,体积小、散热和弯折可靠性平衡良好。
  • 设计用于总线环境的差分收发,对常见干扰具有良好抗扰性(需配合系统设计)。

三、典型技术参数

  • 器件类型:CAN-FD 收发器
  • 最大数据速率:5 Mbps
  • 工作电压:4.5V ~ 5.5V
  • 工作温度:-40℃ ~ +150℃
  • 封装形式:SOP-8
  • 品牌:SIT(芯力特)

(注:以上为核心参数摘要,具体电气特性如输入/输出电平、时序、静态电流、欠压/热保护等请参见厂商详细规格书。)

四、封装与引脚说明

SIT1051AT 采用标准 SOP-8 封装,适合自动化贴装与波峰/回流焊工艺。典型 CAN 收发器在此封装中会包含 VCC、GND、CANH、CANL、TXD、RXD 以及若干控制/状态引脚(如 EN/STB、RS 等),在设计前应参阅官方引脚图和封装尺寸以确认焊盘与散热方案。

五、应用场景

  • 汽车电子:动力控制模块、车身控制单元、车载网关等需耐高温的车载通信节点。
  • 工业控制:工业现场总线、高速数据采集与PLC 通信接口。
  • 能源与电力:逆变器、BMS 与功率电子设备附近的通信接口。
  • 其他:需要 5V 供电且要求高可靠通信的嵌入式系统。

六、设计使用建议与注意事项

  • 总线终端:在总线两端采用 120Ω 差分终端电阻以匹配阻抗,减少反射。
  • 电源旁路:在 VCC 近引脚处放置低 ESR 陶瓷电容(如 0.1µF)并配合适当的滤波,保证瞬态供电稳定。
  • 抗干扰保护:根据应用增加 TVS、共模电感等保护器件,提高抗浪涌与静电能力。
  • 布线与接地:差分线成对布线并尽量短,避免长分支(stub),良好接地与地平面可提升信号完整性。
  • 热管理:尽管器件支持高温工作,靠近热源或大功率器件时应留意散热与寿命影响。

七、可靠性与环境适应性

SIT1051AT 的温度规格扩展至 +150℃,表明其面向高温或严苛环境设计。实际可靠性还需参考厂商的 ESD、热循环、机械应力和寿命试验报告,系统级应用应在整机环境下验证其长期稳定性。

八、总结建议

SIT1051AT 是一款面向高温与高速总线的 CAN-FD 收发器,适合汽车动力舱、工业控制等苛刻环境中的高速差分通信需求。设计时建议结合厂商完整数据手册进行引脚、时序与电气限制检查,并在 PCB 布局、终端与防护电路上采取标准做法,以确保系统性能与可靠性。

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
