TPAX809SS3 是由 TECH PUBLIC(台舟电子)推出的一款低电压检测(Voltage Detector / 复位IC)器件,封装为常见的 SOT-23 三引脚封装。器件对单路电源进行监控,当被监控电压低于设定阈值时产生低电平复位信号,复位保持时间由器件内部定时电路决定,典型复位超时为 140 ms。该器件适合对微控制器、数字逻辑及系统电源进行可靠上电与掉电复位管理。
当被监控电压 VDD 高于阈值 2.63 V 时,TPAX809SS3 释放复位输出,系统开始正常运行;若 VDD 低于阈值或电源出现瞬态下降,器件将输出低电平复位信号,维持约 140 ms 的内部复位超时,确保下游器件进入确定的复位状态,防止逻辑错误或数据损坏。推挽输出提供较强的驱动能力,可直接驱动多数 MCU 的复位输入。
TPAX809SS3 提供标准 SOT-23 三引脚封装,典型功能包括 VDD、GND 与 RESET 三个引脚,便于 PCB 占板空间优化与自动贴装生产。具体引脚排列与封装尺寸请参照 TECH PUBLIC 提供的器件数据手册与封装图。
在选型时确认阈值 2.63 V 是否满足系统上电/欠压保护要求;若系统需不同阈值,可参考同系列其他型号。注意工作温度范围与实际工况匹配,特殊环境(高温、强干扰)下应做额外的可靠性验证与抗干扰设计。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
