SGM809-XXN3L/TR 是圣邦微(SGMICRO)推出的一款低功耗电压监控与复位芯片,集成电压监测、比较与推挽复位输出功能,适用于对单一路电源进行可靠监测并在电压异常时提供系统复位信号。器件采用小尺寸 SOT-23 封装并提供带卷带(TR)包装,便于自动化贴片生产与批量采购。
SGM809-XXN3L/TR 对指定电源电压进行实时监控。当被监控电压低于内置阈值(1.63 V)时,内部比较器触发,器件产生有效低电平的复位输出(RESET↓),向系统发出复位或禁止动作的信号。电压恢复并稳定高于阈值时,复位输出释放回高电平,系统恢复正常工作。
推挽输出结构能够在输出高、低两端均提供有效驱动能力,方便直接驱动 MCU、FPGA 或其他逻辑输入,无需外部上拉或下拉电阻,简化电路设计。
低静态电流(13 μA)使其非常适合电池供电或待机功耗敏感的应用场景;宽温度范围保证芯片在严苛工业或户外环境下仍能稳定工作。
SGM809-XXN3L/TR 提供 SOT-23 小封装,适合表贴工艺与高密度 PCB 设计。型号中的 “XX” 为阈值代码或版本标识,不同代码对应不同阈值或配置,具体命名规则与端子定义请参照圣邦微官方数据手册。尾缀 “TR” 表示卷带包装,方便自动化贴片生产。
总结:SGM809-XXN3L/TR 是一款结构简单、功耗低、推挽输出且适用工业温度的单路电压监控与复位芯片,适合对低电压点(1.63 V)进行可靠监控并提供直接的复位控制,广泛适用于电源管理和系统可靠性设计。更多详细电气特性、典型波形与应用电路建议,请参阅圣邦微官方数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
