CN61CN33产品概述
一、产品简介
CN61CN33是CONSONANCE（上海如韵）推出的一款低功耗电压检测与复位管理芯片，专为3.3V系统及电池供电设备设计。器件提供开漏输出、低电平有效复位信号，用于在供电电压异常时向系统产生可靠的复位脉冲，防止微控制器或外设在欠压条件下工作异常。
二、主要参数
- 芯片类型：电压检测器（监控一路电压）
- 阈值电压：3.3V（监测阈值）
- 工作电压范围：1.15V ~ 5.5V
- 输出类型：开漏（需外部上拉）
- 复位有效电平：低电平有效（/RESET）
- 复位超时：30 μs（复位保持时间）
- 静态电流（Iq）：典型 4 μA
- 工作温度：-40 ℃ ~ +85 ℃
- 封装：SOT-23
三、功能特点
- 低功耗：静态电流仅约4 μA，适合电池供电与低功耗设计。
- 宽电源兼容：1.15V~5.5V的工作电压范围使其可用于多种电源平台。
- 开漏输出：便于与不同电平的系统接口共用，同步多片器件或实现线与逻辑级联。
- 快速复位：30 μs的复位超时适合对短时欠压快速响应的场景。
- 单路监控：针对单一路电压进行可靠检测，结构简单易于集成。
- 工业级温度：-40 ℃~+85 ℃，满足工业和消费类产品的温度要求。
四、典型应用场景
- 单片机、MCU电源监控与复位管理（3.3V系统）。
- 电池供电设备（便携终端、传感器节点、物联网终端）。
- 电源序列控制、上电复位（POR）以及掉电保护电路。
- 各类嵌入式模块、通信设备和外围电路的电压监督。
五、设计建议
- 输出为开漏结构，需要外部上拉电阻（常用10kΩ）至系统逻辑电平（≤5.5V）。上拉电阻值可根据上拉速度与功耗权衡选择。
- 复位为低电平有效，设计时请确认外部电路不会因噪声引入错误复位；必要时可在/RESET线上添加小电容滤波。
- 推荐在VDD引脚附近放置去耦电容（例如0.1 μF）以抑制瞬态噪声，改善检测稳定性。
- 在电源轨上有较大噪声或强干扰时，可适当增加上电滞回或采用硬件上电延时以避免误触发。
六、封装与采购
CN61CN33采用SOT-23小型封装，便于节省PCB空间并完成表面贴装装配。器件由CONSONANCE（上海如韵）提供，可按批量或样品形式采购。产品常用于量产电子设备的电源监控子系统，选择时请参考完整数据手册以获取详细的电气特性、引脚定义及应用电路图。
如需样片测试、电路参考或在特定系统中的应用建议，可提供电路原理图与参数匹配支持，协助快速完成设计验证与量产适配。

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.
