MAX811T 产品概述
一、主要特点
MAX811T 是一款单路电压监控器，适用于对单一供电轨进行复位控制与监测的场合。器件输出为推挽（推挽输出），复位信号为低电平有效（复位有效电平：低）。芯片内部集成手动复位功能，但不包含看门狗定时器。工作电压范围宽：1.2V 至 5.5V，静态工作电流仅 8µA，适合电池供电与低功耗系统。
二、电气性能要点
- 电压阈值：2.84V（阈值电压）；当供电低于该电压时触发复位。
- 复位保持时间：约 140ms（复位超时），保证电源回升阶段系统得到充分复位时间。
- 工作温度：-40℃ 至 +85℃（保证在工业级温度下可靠工作）。
- 受监控电压数：1 路。
三、封装与品牌
- 封装类型：SOT-143，小尺寸、便于占板面积受限的应用。
- 品牌：TECH PUBLIC（台舟电子），适用于替代或设计使用该型号器件的 BOM 列表。
四、典型应用场景
- 电池供电设备（便携电子、仪表）需要低静态电流与准确电压监控；
- MCU 和数字系统上电/欠压复位保护；
- 工业控制与通信设备，在-40℃ 至 +85℃ 环境下保证系统可靠启动。
五、使用建议
- 在 PCB 布局中，SOT-143 的热与接地走线需要与系统其他元件协调，以保证热稳定性和可靠的逻辑电平；
- 若系统需要看门狗功能，应外加独立看门狗方案，因为本器件不含看门狗计时；
- 复位引脚为低电平有效，外部逻辑或上拉电阻需按系统电平正确配置，避免误复位。
如需更详细的电气特性曲线、引脚定义或参考电路图，请索取器件完整数据手册以便进行最终设计验证。

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.
