CN3387 产品概述

一、产品简介

CN3387 是 CONSONANCE(上海如韵)推出的一款面向镍氢电池组的充电管理 DC-DC 芯片。芯片工作于外置器件工作模式,采用 SSOP-10 封装,适合对体积和成本有要求的便携类电源管理设计。设计用于对 4~12 节镍氢电池组进行稳健充电控制,适配多种工业与消费电子应用场景。

二、主要参数

  • 芯片类型:充电芯片(DC-DC 供电架构,外置器件支持)
  • 工作电压:2.7V ~ 6.5V
  • 充电饱和电压:1.205V(参考值)
  • 适配电池:镍氢电池(NiMH),节数 4 ~ 12 节
  • 0V 电池充电:不支持(需外部前级复活电路)
  • 静态电流(Iq):2 µA
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SSOP-10

三、核心特性

  1. 低静态电流:2 µA 静态电流利于延长系统待机寿命,适合低功耗设计。
  2. 宽输入电压范围:2.7V~6.5V,便于从多种电源(适配器、USB、电池)取电并驱动外部 DC-DC 方案。
  3. 支持中等规模电池组:兼容 4~12 节 NiMH 电池,满足常见充电组需求。
  4. 外置器件灵活性:采用外置 DC-DC 及被动元件实现更高的充电电流和功率扩展,系统可按需扩展设计。

四、典型应用

  • 家用/工业便携设备电源管理
  • 无绳电话、便携式工具的镍氢电池充电模块
  • 电池备份与维护充电系统
  • 对成本与封装要求较高的消费电子设备

五、设计与使用注意事项

  • 由于芯片不支持 0V 电池直接充电,若需对深度放电或开路电池进行复活,必须在前端加入独立的唤醒/预充电电路。
  • 充电饱和电压 1.205V 为参考值,实际系统应根据电池厂商推荐和温度补偿策略设定终止逻辑与监控阈值,防止过充或欠充。
  • 外置 DC-DC 与功率器件选择应根据目标充电电流和效率要求合理配置,并注意散热与电磁兼容性。
  • PCB 布局时应重视地线回流、输入/输出去耦和 SSOP-10 管脚焊盘规范,保证稳定性与可靠性。
  • 工作环境温度在 -40 ℃ 至 +85 ℃ 范围内,严苛环境下建议进行完整热测试与老化验证。

六、封装与可靠性

CN3387 提供 SSOP-10 封装,适合常规 SMT 生产流程。结合低静态电流与宽温度规格,可在工业级与消费级产品中长期可靠工作。选型时请参照厂商完整数据手册进行电气特性与典型应用电路设计,以确保系统安全与性能达标。

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
