CAT809STBI-GT3-MS 是美森科(MSKSEMI)推出的一款低功耗电压监控器(复位芯片),采用 SOT-23 封装。器件对单路电源进行监控,当被监控电压低于门限电压 2.93V 时,会产生低电平有效的复位信号,典型复位脉宽为 240ms。工作电压范围宽(1.0V~5.5V),并能在 -40℃~+125℃ 的工业级温度下稳定工作,适合便携式音频及消费类电子产品的电源监测与复位保护。
当被监控电压持续低于 2.93V 时,CAT809STBI-GT3-MS 将输出一个低电平复位信号,抑制系统进入不确定状态;当电压恢复到阈值以上并保持一定时间后(复位超时 240ms),器件释放复位,输出回到高电平,使系统能可靠上电启动。推挽输出能提供更稳定的驱动能力,适合直接拉高或拉低下游逻辑电平。
(详尽的动态参数、输入漏电流、输出驱动能力及时序特性请参见官方数据手册)
器件采用 SOT-23 小型封装,占板面积小,适合移动设备与便携终端的空间优化设计。SOT-23 的引脚排列与常见复位器件兼容,便于替代或升级现有设计。
CAT809STBI-GT3-MS 是一款性能稳定、封装紧凑的低功耗电压监控器,凭借 2.93V 的精确阈值、240ms 的复位保持时间以及推挽输出特性,适用于对上电行为和欠压保护有严格要求的便携式音频与消费电子产品。对于需要可靠上电初始化和抗电源瞬态能力的设计,CAT809STBI-GT3-MS 提供了简洁且高效的解决方案。有关更详细的时序、功耗与典型应用电路,请参阅厂商提供的数据手册。

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.
