SIT1044QT 产品概述
一、产品简介
SIT1044QT 是芯力特（SIT）推出的一款 CAN-FD 总线收发器，专为需支持扩展数据速率与严苛工作环境的工业与车载系统设计。器件兼容 CAN-FD 协议，支持高达 5Mbps 的数据传输速率，并在 -40℃ 至 +125℃ 的温度范围内稳定工作，适合工业级与汽车级应用。
二、主要性能指标
- 类型：CAN-FD 收发器
- 最大数据速率：5 Mbps
- 工作电压：4.75 V ~ 5.25 V
- 工作电流（典型）：30 μA
- 静态电流：30 μA
- 工作温度：-40℃ ~ +125℃
- 品牌：SIT（芯力特）
- 封装：SOP-8
三、产品特点与优势
- 高速传输：支持 CAN-FD 规范下 5 Mbps 的数据速率，满足高带宽数据交换需求。
- 低功耗：工作与静态电流均为 30 μA（典型），适合对能耗敏感的系统与长时间待机应用。
- 宽温度范围：-40℃ 至 +125℃ 覆盖工业与汽车级环境，可靠性高。
- 标准封装：SOP-8 便于替换与批量组装，适配现有 PCB 布局。
四、典型应用场景
- 汽车电子网络（车身控制、车载网关）
- 工业自动化总线系统（现场总线、PLC 通信）
- 医疗仪器、楼宇控制与能源管理等需要可靠通讯与低功耗的场合
五、封装与引脚信息
SOP-8 封装适合通过波峰或回流焊工艺装配。建议在 VCC 与 GND 之间放置 0.1 μF 陶瓷去耦电容，并在差分线两端根据系统布局配备 120 Ω 终端电阻以及必要的共模滤波器或瞬态抑制器以提高 EMC 性能与抗干扰能力。
六、使用建议与可靠性
为保证通信稳定性与长期可靠性，建议：
- VCC 采用清洁电源，近端放置去耦电容；
- CAN_H / CAN_L 差分线保持对称、阻抗匹配并尽量避免信号线并行；
- 系统级加入短路保护与 ESD 防护元件；
- 在高温或振动环境下进行完整的系统验证与寿命预测。
SIT1044QT 提供兼具高速、低功耗与工业耐受性的 CAN-FD 收发能力，是工业与汽车网络设计中的稳健选择。若需更详细的电气特性曲线、典型应用电路或样片支持，可联系厂商技术服务获取完整数据手册。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
