CN825Z 产品概述
一、产品简介
CN825Z 是由 CONSONANCE（上海如韵）推出的一款低功耗电源监控器芯片，集成看门狗定时器和手动复位功能，适用于对单路电源进行可靠监控与系统复位控制。芯片封装为 SOT-23-6，工作温度范围宽（-40℃～+85℃@(Ta)），工作电压范围 1.1V ～ 6.5V，专为电池供电与低功耗嵌入式系统设计。
二、主要特性
- 复位输出支持两种极性：低电平有效或高电平有效，满足不同系统复位接口需求；
- 内置看门狗定时器，防止软件失陷时系统长期停滞；
- 提供手动复位输入，便于外部按键或控制器强制复位；
- 超低静态电流 Iq = 16 μA，有利于延长电池寿命；
- 基准阈值电压 2.32V（典型），对单路电源进行精确监测；
- 复位保持时间（复位超时）约 200 ms，确保上电或复位后微控制器稳定启动；
- 支持 1.1V～6.5V 宽电压工作范围，适配多种供电方案；
- 封装：SOT-23-6，体积小，易于自动贴装。
三、功能说明
CN825Z 在电源电压低于阈值时输出复位信号，保证 MCU 和关键外设在电源不稳时处于复位状态，防止异常运行。看门狗定时器需由系统周期性“喂狗”（软件或外部脉冲）以避免超时触发复位，从而提供对软件死循环和异常状态的保护。手动复位引脚允许用户通过按键或外部逻辑直接触发复位，便于调试与人为干预。
四、应用场景
- 低功耗物联网节点、传感器终端；
- 电池供电的便携设备与可穿戴设备；
- 工业控制、仪器仪表和家用电器控制板；
- 汽车电子（非车规级应用需验证）；
- 所有需高可靠启动与软件自恢复的嵌入式系统。
五、设计注意事项
- 将 VDD 连接到被监控的电源轨，GND 接系统地；复位输出连至 MCU 复位引脚；手动复位按钮或外部逻辑应避免产生毛刺，可并联去抖电路或 RC 滤波；
- 在有强电磁干扰或长走线的环境下，建议在 VDD 与 GND 之间增加去耦电容以提高稳定性；
- 根据系统对复位极性的需求，选取相应的输出极性版本或在上位电路进行逻辑转换；
- 留意看门狗的服务策略，确保在中断或低功耗待机场景下不会误触发看门狗复位。
CN825Z 以其低功耗、宽电压、集成看门狗与手动复位功能，为需要可靠电源监控与自动恢复能力的嵌入式系统提供了一种紧凑且易用的解决方案。若需更详细的电气特性曲线、典型应用电路或封装引脚定义，请参考 CN825Z 的完整数据手册或联系 CONSONANCE 客服技术支持。

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.
