CN305 产品概述
一、产品简介
CN305 是 CONSONANCE（上海如韵）推出的一款双路低功耗比较器，采用 SOT-23-6 小封装，工作电源范围宽（1.9V ~ 6V），工作温度 -40℃ ~ +85℃。器件输出为开漏结构，静态工作电流仅 11μA（typ），传播延迟约 15μs，适合对功耗敏感且对速度要求不高的各类检测与比较应用。
二、主要特点
- 双路比较器，节省 PCB 空间与器件成本。
- 输出类型：开漏（open-drain），便于与不同电平系统和外部拉高电阻连接。
- 低静态电流 Iq ≈ 11μA，适合电池供电与节能场景。
- 传播延迟 tpd ≈ 15μs，适用于低频或慢速信号检测。
- 单电源供电：1.9V ~ 6V，可直接与常见 MCU、传感器电源共用。
- 封装：SOT-23-6，体积小，便于批量自动贴装。
三、典型应用
- 电池电压监测与低电压报警
- 传感器阈值检测（温度、光照、压力等）
- 电源管理与电池保护电路
- 门限比较、施密特触发（可外部加滞后）
- 工业控制与仪表中的低速比较场景
四、使用建议与电路要点
- 由于输出为开漏，必须外接拉高电阻至所需逻辑电平（不超过器件 VCC）。典型值：若优先低功耗，可选 10k；若需较快上升沿，可选 2.2k–4.7k。
- 传播延迟 ~15μs，故不适合高频精确定时的应用；用于几十 kHz 以下比较与检测更为合适。
- 建议在 VCC 与 GND 之间并联 0.1μF 陶瓷去耦电容，靠近器件电源引脚放置，减少电源噪声对比较精度的影响。
- 输入端避免超过电源轨（超出 VCC 或低于 GND），如可能出现超限，应在输入端串联限流电阻或加钳位二极管。
- 若需抗抖动或确定清晰开关边沿，建议对某一路加小量正反馈构成滞后（施密特型），外部通过电阻网络实现。
五、封装与订购信息
- 品牌：CONSONANCE（上海如韵）
- 型号：CN305
- 封装：SOT-23-6（适合自动化贴装）
- 应在订购时确认完整的器件标识、批次与包装，以便于可靠性与版本追溯。
六、注意事项
- 在高温或高噪声环境下，比较器的偏置与漂移可能影响阈值精度，应在系统设计中预留校准或滤波手段。
- 输出为开漏，不具备主动输出高电平能力，外接拉高电阻及拉高电压需与系统逻辑兼容。
- 在实际设计前如需更详细电气特性（输入失调电压、最大输出电流、输入共模范围等），建议参考 CN305 的完整数据手册或与供应商技术支持确认。
总体而言，CN305 以其低功耗、小封装和宽电源范围，适用于多种要求低静态电流、低速比较的便携与工业应用。

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.
