CN3058E 磷酸铁锂电池管理芯片（SOP-8-EP）产品概述
一、产品简介
CN3058E 是 CONSONANCE（上海如韵）推出的一款面向单节磷酸铁锂（LiFePO4）电池的电池管理芯片，采用 SOP-8-EP 封装，集成低静态电流充电管理和电池温度检测功能。器件专为对体积、功耗和可靠性有较高要求的便携与工业设备设计，支持最高 1A 的恒流充电能力，适配单节 3.2V 标称的磷酸铁锂电池充电要求。
二、关键性能参数
- 最大充电电流：1A（可通过外围元件设定与限制）
- 充电饱和电压（终止电压）：3.6V（符合 LiFePO4 充电规范）
- 工作电压范围：3.8V ~ 6V（供应电压需高于充电电压以保证正常工作）
- 静态电流（Iq）：约 3μA（低待机功耗，适合低功耗系统）
- 工作温度范围：-40℃ ~ +85℃
- 电池节数：1 节磷酸铁锂电池
- 电池温度检测：支持（用于温度保护和充电策略判断）
- 封装：SOP-8-EP（带散热焊盘，便于 PCB 散热设计）
三、功能特性
- 针对 LiFePO4 的恒流-恒压（CC/CV）充电算法，充至 3.6V 并在电流下降至终止电流时完成充电。
- 集成低静态电流的待机设计，适合电池供电或长期待机场景。
- 支持电池温度检测接口（NTC），可实现过温/欠温充电抑制，提升安全性与电池寿命。
- SOP-8-EP 带散热焊盘，利于在 1A 充电条件下进行热管理与 PCB 散热。
四、典型应用场景
- 智能表计、IoT 终端、无线传感器、便携式工业设备
- 备用电源、应急照明、手持工具与小型医疗设备
- 任何采用单节磷酸铁锂电池并需稳定、长寿命充电管理的系统
五、设计与使用建议
- 输入电源需高于充电饱和电压并留有足够裕量（建议 ≥ 5V 在 1A 充电时以保证器件头部余压）。
- 在 PCB 设计上充分利用 SOP-8-EP 的热焊盘进行散热，必要时配合铜箔加厚或热孔过孔以降低结温。
- 使用外置电流检测或限流元件时，请按器件手册或参考电路选择合适的取样电阻与滤波，确保准确的充电电流设定与安全保护。
- 电池温度检测建议采用常用 10k NTC 或按资料指定类型，以实现准确的温度门限控制。
- 系统应增加输入反接保护、热关断和定时器等冗余安全措施，满足产品安规与可靠性要求。
六、采购与技术支持
CN3058E 由 CONSONANCE（上海如韵）供应，封装为 SOP-8-EP，适合自动贴片加工。对接采购或获取参考设计与资料时，请向供应商索取完整数据手册、参考电路与热设计建议，以便在目标应用中实现最佳性能与安全性。

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.
