TCM809SVNB713 是 Microchip(美国微芯)出品的一款单通道电压监控与复位芯片,采用 SOT-23 小封装,适用于对单一路电源进行可靠的上电复位与低电平复位监控。器件工作电压范围为 1.0 V 至 5.5 V,复位为低电平有效(RESET#),输出为推挽驱动,标准复位脉冲宽度约为 140 ms,工作结温范围为 -40 ℃ 至 +125 ℃,适配工业级温度要求。
TCM809SVNB713 在电源上电或电压下降时持续监测 VCC。一旦被监控电压低于内部设定阈值(4.63 V),器件将把复位输出(RESET#)拉低,强制被监控系统进入复位状态;当电压回升并稳定高于阈值后,器件在内部延时(约 140 ms)后释放复位,确保被监控系统有足够时间完成上电初始化。由于输出为推挽结构,可直接驱动目标芯片的复位脚或外部逻辑,无需外部上拉,提高系统简洁性和响应可靠性。
TCM809SVNB713 以其宽电压范围、推挽输出、低电平有效复位以及 140 ms 的可靠复位保持时间,为需要稳定上电复位和欠压保护的电子系统提供了简洁而可靠的解决方案。其 SOT-23 小封装和工业级温度适应能力,使其非常适合空间受限且对可靠性要求较高的便携与嵌入式应用。在设计中合理匹配阈值并注意去耦与布局,可充分发挥该器件在系统复位管理中的作用。

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.
