SGM809-ZXN3/TR 是由圣邦微(SGMICRO)推出的一款单路电压监控器(复位 IC),采用 SOT-23 小封装并以带卷装(TR)方式供货。器件用于对系统供电电压进行实时监测,在监控电压异常时产生复位信号,保证微控制器和数字逻辑在电源不稳时不会进入不可预测状态。器件工作温度范围宽(-40℃ 至 +125℃,Tj),适合工业级应用。
当被监控电压下降至低于 2.32 V 时,器件将把复位输出拉至高电平,向系统发出复位请求;当电压回升超过阈值后,器件在内部定时 240 ms 后释放复位(复位输出返回低电平),为电源和时钟稳定提供缓冲时间。推挽输出能直接驱动后级复位引脚或外部指示器,无需上拉电阻。
SOT-23 小尺寸封装便于在空间受限的板级设计中应用,TR(带卷装)适合自动化贴片生产。-40℃ 至 +125℃ 的工作温度范围满足多数工业与汽车电子周围环境要求(请参考数据手册以确认具体的热性能与焊接规范)。
总结:SGM809-ZXN3/TR 提供稳定的单电压监控与 240 ms 复位保持时间,封装小、温度范围宽,适合对系统可靠性有严格要求的各种电子设备。欲获取更详细的电气参数、引脚定义和典型应用电路,请参考厂商完整数据手册。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
