CN803S 产品概述
一、主要特性
CN803S 是上海如韵（CONSONANCE）推出的一款单电压电源监控器，采用 SOT-23 封装，专为低功耗系统设计。关键参数包括：工作电压 1.15V～5.5V、复位阈值 2.93V、复位超时 140ms、静态电流仅 3.2µA、工作温度范围 -40℃～+85℃。复位输出为开漏且为低电平有效，不带看门狗与手动复位功能。
二、产品功能与工作原理
CN803S 监测单路供电电压，当被监控电压低于 2.93V 时，器件将把 RESET 拉低（开漏），并在电压回到正常后延时约 140ms 才释放复位，确保系统在电源恢复期间有稳定的上电时间窗口，避免因电源抖动造成错误复位。
三、典型应用场景
- 便携式与电池供电设备的电压监测与复位保护
- 工业控制、仪器仪表中 MCU 的上电复位电路
- 低功耗物联网节点、传感器模块的电源监督
- 任何需在 1.15V～5.5V 范围内保证可靠复位的嵌入式系统
四、封装与引脚（典型）
三引脚 SOT-23 封装，典型引脚功能为：VCC（供电）、GND（接地）、RESET（开漏输出，低电平有效）。该封装利于空间受限的系统集成。
五、设计建议
- RESET 为开漏输出，设计时需外接上拉电阻到所需复位电平（常接至 VCC 或 MCU 的 I/O 电压）。
- 在关键电源线上加适当去耦电容以抑制瞬态干扰，保证阈值检测稳定。
- 复位超时 140ms 适合大多数 MCU 上电初始化，如需更长复位时间可配合外部电路延长。
- 由于不具备看门狗功能，系统若需死机恢复请另行增加看门狗方案。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
