CAT811STBI-GT3-MS 产品概述

一、产品简介

CAT811STBI-GT3-MS(品牌:MSKSEMI/美森科)是一款低功耗电压检测器,工作电压范围为1.0V至6.0V,针对单路电源监控设计。器件在被监控电压低于阈值2.93V时产生低电平有效复位信号,支持手动复位功能,采用推挽输出结构,复位保持时间为240ms,适合用于对供电瞬态和启动过程进行可靠复位控制的场景。

二、主要规格

  • 芯片类型:电压检测器(Voltage Detector)
  • 输出类型:推挽输出(Push-Pull)
  • 工作电压:1.0V ~ 6.0V
  • 复位有效电平:低电平有效(Active Low)
  • 阈值电压:2.93V(监测电压阈值)
  • 受监控电压数:1路
  • 手动复位:具备(外部触发复位)
  • 看门狗定时器:无
  • 复位超时:240ms(复位保持时间)
  • 工作温度:-40℃ ~ +125℃
  • 静态电流(Iq):典型5µA(低功耗)
  • 封装:DO-214AA(SMB)

三、功能与优势

  • 低工作电压与宽范围供电(1V~6V),适配普通单节锂电池及多种低压系统。
  • 推挽输出可直接驱动上拉或下拉负载,无需外部上拉电阻,改善上/下拉响应速度与抗干扰能力。
  • 低静态电流(约5µA),有利于电池供电设备延长待机时间。
  • 240ms的复位超时保证在上电和掉电瞬态期间为被控设备提供足够的复位宽裕,提升系统登录和初始化稳定性。
  • 宽温范围(-40℃~+125℃)满足工业级应用要求。
  • 手动复位输入为系统调试、固件更新或外部故障时提供简单可靠的人工复位手段。

四、典型应用

  • 单片机/微处理器复位管理(上电复位、掉电保护)
  • 电池供电的便携式设备(手持终端、测量仪器)
  • 工业控制设备、电源监控与保护模块
  • 嵌入式系统的可靠启动与看门监控(作为独立电压监测单元)
  • 需要低静态电流和宽温域的户外或环境苛刻应用

五、设计要点与使用建议

  • 复位引脚连接:将复位输出直接连至微控制器复位输入,若系统对上拉有特殊要求请参考推挽输出特性选择合适的终端电阻或缓冲器。
  • 去抖与滤波:如电源噪声较大,可在被监控电压线上增加适度去耦电容以抑制短脉冲误触发;但需注意过大的电容可能影响上电检测响应。
  • 手动复位:手动复位端设计为外部开关到地或外加驱动,确保按下或触发时能将复位信号拉低并维持至少器件规定的最小脉宽。
  • 温度与封装:DO-214AA(SMB)封装热容与机械强度较好,请在PCB布局中考虑焊盘和散热路径,确保在高温或功耗场景下可靠性。
  • ESD与保护:在有强电磁干扰或静电风险的环境下,增加适当的ESD保护与滤波元件以提高系统鲁棒性。

六、可靠性与选型提示

CAT811STBI-GT3-MS以其低功耗、明确的阈值和工业温度等级适合要求长期可靠工作的产品。在选型时请确认阈值2.93V是否满足系统复位窗口,并考量封装形式(DO-214AA/SMB)对PCB空间与装配工艺的影响。若需集成看门狗或多路监控功能,可在系统层面结合其它器件实现。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
