CN809M 是由 CONSONANCE(上海如韵)推出的一款低功耗电压监控器(复位 IC),采用 SOT-23-3 封装。器件工作电压范围宽(1.15V 至 5.5V),静态电流仅 3.2µA,适合电池供电和低功耗系统。复位输出为低电平有效,典型阈值电压为 4.38V(单路监控),复位超时约 140ms,工作温度范围 -40℃~+85℃。
当被监控电压低于阈值(4.38V)时,CN809M 将输出低电平以保持系统在复位态;当电压回升并超过阈值且稳定后,器件继续保持复位时间约 140ms,随后释放复位,确保系统稳定启动。器件不含看门狗定时器及手动复位按钮接口,如需这些功能可在外部电路中补充。
型号:CN809M
品牌:CONSONANCE(上海如韵)
封装:SOT-23-3
在选型或批量采购前,建议下载并参阅器件完整数据手册,确认阈值容差、输出类型(开漏/推挽)、极限参数与封装标识,以满足最终系统设计需求。

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.
