CN1185 产品概述
一、产品简介
CN1185 是 CONSONANCE（上海如韵）推出的一款多路电压检测与复位监控芯片，属于电压检测器/复位 IC 类别。器件提供开漏输出，可对多达 4 路受监控电压进行检测，并在检测到电压低于阈值时产生复位信号。器件工作电压范围宽（2.7V 至 6V），工作温度范围为 -40℃ 至 +85℃，静态电流仅 7.3µA，适合低功耗系统的上电监控与电源完整性保障。封装为 TSSOP-16，便于中小批量到工业级应用。
二、主要性能特点
- 芯片类型：电压检测器 / 复位 IC
- 输出类型：开漏（需要外部上拉）
- 工作电压：2.7V ~ 6V，兼容常见单电源与双电源系统
- 受监控电压路数：4 路，支持多电源轨监控
- 工作温度：-40℃ ~ +85℃，满足工业级温度要求
- 静态电流（Iq）：7.3µA，适合电池供电与低功耗场景
- 封装：TSSOP-16，利于散热与 PCB 布局
三、功能与工作原理
CN1185 对被监控的电源轨进行连续监测，当任一路电压降至预设阈值以下时，器件将通过开漏输出拉低复位信号，通知系统进入复位或受控状态，以防止系统因欠压而出现运行异常。开漏输出便于多个监控器并联或与外部逻辑电平兼容；外部上拉电阻可根据系统电平与速度要求选取合适阻值。器件的低静态电流设计在系统待机或睡眠时最大限度减少能耗。
四、典型应用场景
- MCU/MPU 的电源上电复位与欠压保护
- 多电源系统（如数字核、模拟核、I/O 电源）的统一监控与顺序控制
- 电池供电设备的电源完整性检测（如便携式仪器、手持终端）
- 工业控制与通信设备中的可靠性提升方案
- 系统复位链路的冗余与外设复位控制
五、使用建议与注意事项
- 由于输出为开漏结构，必须外接合适的上拉电阻至目标逻辑电平；上拉电阻阻值影响上升时间与功耗，典型取值范围为 10kΩ～100kΩ，具体应根据系统需求调整。
- 为保证电压检测精度与稳定性，建议在 VCC 端放置 0.1µF 旁路电容并尽量靠近器件引脚布局，减小噪声与瞬态影响。
- 在多路检测场合，合理规划各被监控电压的采样与滤波，避免瞬态脉冲误触发复位。
- TSSOP-16 封装需注意焊盘设计与散热，严格按照制造商推荐的 PCB 焊盘与回流温度曲线进行组装。

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.
