SIT1044T(芯力特)CAN‑FD收发器 产品概述

一、产品简介

SIT1044T 是芯力特(SIT)推出的一款面向汽车与工业总线应用的 CAN‑FD 收发器,采用 SOP‑8(150 mil)封装。器件工作电压为典型的 5V(工作电压范围 4.75V ~ 5.25V),支持 CAN‑FD 数据速率,满足现代车辆与工业控制器对高带宽数据传输的需求。其设计兼顾高速数据通信能力与低功耗特性,可在极端环境下稳定工作(工作温度范围 -40°C ~ +125°C),适合严苛可靠性要求的系统。

二、主要规格参数

  • 类型:CAN‑FD 收发器
  • 工作电压:4.75V ~ 5.25V(典型 5V)
  • 工作温度:-40°C ~ +125°C(工业/车规级温度范围)
  • 数据速率:最高可支持 5 Mbps(FD 数据相)
  • 工作电流(活动态):约 70 mA
  • 静态电流(待机/睡眠态):约 30 μA
  • 封装:SOP‑8 (150 mil)
  • 品牌:SIT(芯力特)

三、功能与特点

  • 支持 CAN‑FD:支持高达 5 Mbps 的数据传输速率,满足 CAN‑FD 中数据相较传统 CAN 更高带宽的需求。
  • 低待机功耗:静态电流仅约 30 μA,适合需长时间待机或低功耗策略的系统设计。
  • 宽温域工作:-40°C 至 +125°C 的工作温度覆盖典型汽车与工业环境。
  • 标准化封装:SOP‑8(150 mil)封装便于通过常规 SMT 工艺进行组装和替换。
  • 可靠通信:活动态工作电流约 70 mA,保证在负载与总线激活时有稳定驱动能力。

(注:以上参数来自基础信息汇总,具体功能细节请参考芯力特官方数据手册以获得完整电气特性与时序说明。)

四、典型应用场景

  • 汽车域控制器(车身控制单元、车载网关、ADAS 相关模块)
  • 工业控制与自动化系统(PLC、现场总线接口)
  • 电机控制器与逆变器通信接口
  • 车载诊断与数据记录设备
  • 任何需要在 5V 总线环境中实现 CAN‑FD 通信的嵌入式系统

五、封装与引脚(概览)

SOP‑8(150 mil)常见于小尺寸但易于焊接的中等引脚数器件。SIT1044T 的封装便于与多数 PCB 设计流程兼容。典型引脚包括 VCC、GND、TXD、RXD、CANH、CANL、及电源/模式相关引脚(详细引脚排列与功能请参照官方引脚图与数据手册)。

六、设计与布板建议

  • 电源去耦:VCC 端近旁放置 0.1 μF 陶瓷去耦电容,并配合一个 4.7–22 μF 的旁路电容用于抑制低频波动。
  • 总线终端与匹配:在总线两端采用 120 Ω 终端电阻,必要时在器件附近加入共模电感或小阻值串联电阻(22–33 Ω)以改善信号完整性与振铃。
  • TVS 与浪涌保护:在 CANH/CANL 线上配合 TVS 二极管和浪涌保护元件,用于增强抗瞬态过压能力与 ESD 性能。
  • 布线注意:CANH 与 CANL 保持差分对布线,线长匹配、靠近接地平面,减少干扰。尽量避免在差分对附近穿越高速信号或开关电源走线。
  • 接地策略:使用单一地平面或低阻抗回流路径,减少地环路与共模干扰。

七、可靠性与注意事项

  • 热管理:SOP‑8 封装的散热依赖 PCB 铜面积与走线,若长时间高负载工作应增加散热铜箔或使用更大接地平面以降低结到环境的热阻。
  • ESD 与浪涌:尽管设计用于恶劣环境,仍建议在 PCB 级别加入 ESD/浪涌防护器件以提升系统可靠性。
  • 电源序列:严格按数据手册中推荐的电源上电/下电顺序与滤波要求执行,以防止错误工作或损伤器件。
  • 测试与验证:在最终系统中进行电磁兼容(EMC)、总线冲突、长线通信与温度循环验证,确保在目标应用场景长期稳定运行。

八、采购与封装信息

  • 型号:SIT1044T
  • 品牌:SIT(芯力特)
  • 封装:SOP‑8(150 mil)
  • 建议在采购前向供应商或芯力特官方索取最新数据手册、器件可靠性报告与 AEC‑Q100(若适用)认证信息,以确认器件满足具体项目的质量与认证要求。

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
