CN803R 产品概述
一、产品简介
CN803R 是 CONSONANCE（上海如韵）推出的一款单路电压监控器（Voltage Monitor），采用 SOT-23-3 封装，工作电压范围宽（1.15V～5.5V），专为微控制器和数字系统提供可靠的复位功能。器件静态电流低，仅 3.2 μA，适合电池供电与低功耗应用。复位有效为低电平（低电平有效），输出为开漏结构，便于与外部上拉电阻和多片级联使用。
二、关键参数
- 监控路数：1 路
- 阈值电压：2.63 V（典型）
- 工作电压：1.15 V ～ 5.5 V
- 复位超时：140 ms（典型）
- 复位有效电平：低电平有效
- 输出类型：开漏（Open-drain）
- 静态电流（Iq）：3.2 μA（典型）
- 工作温度：-40 ℃ ～ +85 ℃
- 看门狗/手动复位：无
- 封装：SOT-23-3
三、功能特性
- 稳定的低压检测：当 VCC 低于 2.63 V 时，器件将产生复位输出，保证被监控系统在电源异常或上电过程中处于确定状态。
- 自动复位延时：复位信号持续约 140 ms，确保系统在电源恢复后有足够时间完成初始化。
- 开漏输出：允许与不同电压域的上拉电阻连接，便于多设备共享总线或与外部逻辑兼容。
- 低功耗设计：3.2 μA 的静态电流适合长期供电或电池供电系统。
四、典型应用
- 单片机、DSP 等微处理器的电源监控与复位。
- 电池供电设备、可穿戴设备与物联网终端。
- 工业控制、消费电子、通信设备的可靠上电与掉电保护。
- 多电源系统中的电压监督与复位链路。
五、设计与使用建议
- 由于输出为开漏，需在复位输出端接适当阻值的上拉电阻（典型 10 kΩ），上拉电压应与目标逻辑电平一致。
- 在芯片 VCC 引脚附近放置去耦电容（例如 0.1 μF）以抑制瞬态噪声，避免误触发。
- 将 CN803R 靠近被监控的逻辑芯片布置，减少走线感应和杂散电阻带来的误差。
- 对于关键应用，建议参考完整数据手册确认迟滞、电平公差和温漂等详细特性。
六、封装与采购信息
- 型号：CN803R
- 品牌：CONSONANCE（上海如韵）
- 封装：SOT-23-3，适合自动贴片生产与小体积设计。
CN803R 因其低功耗、简单可靠的复位特性，适用于需要稳定上电复位且对外设兼容性有要求的嵌入式系统。选择时请参照制造商数据手册以获得完整电气特性与使用限制。

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.
