SGM804-2.63YN5G/TR 是 SGMICRO(圣邦微)推出的一款低电压监控复位芯片,采用 SOT-23-5 封装,适用于各种微控制器和系统电源监督场景。器件监控单路电压,当被监控电压低于阈值时输出主动复位信号;器件工作电压范围宽(1.0 V 至 5.5 V),适配电池供电与常见单电源系统。该型号阈值电压为 2.63 V,复位为低电平有效,复位脉冲最短保证时间为 4.25 ms。
当被监控的 VCC(或指定电源轨)低于 2.63 V 时,SGM804-2.63YN5G/TR 会将 RESET 输出拉为低电平,向系统发出复位请求,保证系统处于已知初始状态;当电压回升到阈值之上并稳定后,器件继续保持 RESET 低电平至少 4.25 ms(复位超时),随后释放复位(RESET 回到高电平),确保上电/掉电切换期间系统完成初始化。推挽输出可直接驱动多数 MCU 的复位引脚,无需外部上拉电阻(但应参考系统电平与负载能力)。
SGM804-2.63YN5G/TR 提供 SOT-23-5 小封装,适合空间受限的便携与嵌入式设备。器件在 -40 ℃ 到 +85 ℃ 的温度范围内工作,满足大多数工业级与商业级应用的环境要求。
小结:SGM804-2.63YN5G/TR 以其宽工作电压、固定 2.63 V 阈值和推挽输出特性,为需要可靠上电/欠压复位且体积受限的系统提供了简洁有效的电压监控解决方案。

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.
