CN825R 产品概述

一、概述

CN825R 是由 CONSONANCE(上海如韵)推出的一款低功耗电源监控器芯片,集成电压检测、看门狗定时器与手动复位功能。芯片采用 SOT-23-6 封装,面向嵌入式系统、低功耗物联网节点、电池供电设备及工业控制等场景,提供可靠的电源复位与系统看护能力。

二、主要参数

  • 工作电压范围:1.1V ~ 6.5V
  • 监控电压路数:1 路
  • 阈值电压(典型):2.63V
  • 复位保持时间(复位超时):200 ms
  • 静态电流(Iq):2.7 μA
  • 温度范围:-40 ℃ ~ +85 ℃
  • 复位有效电平:支持低电平有效或高电平有效配置
  • 附加功能:看门狗定时器;手动复位输入(外部按键或控制信号)

三、功能特点

  • 低功耗设计:静态电流仅 2.7 μA,适合电池供电和能耗敏感设备。
  • 宽电压工作范围:1.1V 至 6.5V,兼容多种单/多电池与稳压供电架构。
  • 稳定的上电/欠压复位:阈值 2.63V(典型),在电压下降或上电不稳时产生可靠复位脉冲,复位时间约 200 ms,保障系统上电稳定。
  • 看门狗功能:内置看门狗定时器,可在主控失控或死循环时触发复位,提升系统可靠性。
  • 手动复位:外接按键或控制信号可触发复位,方便调试与人工干预。
  • 抗干扰能力强:适合工业与现场环境,工作温度覆盖宽温区间。

四、典型应用

  • MCU/MPU 复位管理与电源监控
  • 物联网节点、无线传感器和遥测设备
  • 电池供电装置、便携式电子产品
  • 工业控制器、楼宇/安防设备等需要高可靠复位的系统

五、使用建议

  • 复位阈值与系统最小工作电压配合设计,确保在电压跌落期间主控已安全停机或保持复位。
  • 看门狗功能应结合定期喂狗机制使用,避免误触发;若系统需要可配置看门狗超时时间或加外部延时元件以满足应用需求。
  • 手动复位按键应接至指定复位输入,设计滤波或防抖电路以避免抖动误触发。
  • SOT-23-6 封装便于 PCB 布局与散热,建议靠近被监控芯片布置减小走线感应与寄生。

CN825R 以其低功耗、宽电压范围和集成看门狗/手动复位特性,为需要高可靠电源监控与复位管理的各种电子系统提供经济、稳定的解决方案。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
