MAX811SEUS+T 是一款用于微处理器/微控制器电源监控的低功耗 supervisor 芯片,适用于 1.0V 至 5.5V 的电源系统。主要参数包括:单路电压监控、监测阈值为 2.63V、主动低电平复位(RESET 为低有效)、开漏输出、带手动复位按键输入、复位维持时间约 140ms、典型静态电流仅 10µA,工作温度范围 -40℃ 至 +85℃,封装为 SOT-143-4,品牌为 ADI/Linear,带卷带包装(+T)。
芯片持续监测单路系统电源电压。当被监控电压低于内部阈值(2.63V)时,器件将把 RESET 引脚拉为低电平以保持系统复位;当电压回升并稳定超过阈值后,器件在内置的复位超时(典型 140ms)后释放 RESET,使系统可靠上电。器件提供一个手动复位输入(通常标为 MR),外部按键或逻辑信号可强制产生低电平复位。输出为开漏类型,便于与多设备线或外部上拉电阻配合使用。
MAX811SEUS+T 适合对单一路电压进行可靠监控且要求极低静态电流的应用。若需要不同阈值、推挽输出或内置看门狗功能,可参考同系列或同类器件并核对输出类型与阈值公差。购买时注意后缀 +T 表示卷带包装,便于自动化贴片生产。

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.
