ETA6002E8A 产品概述

一、产品简介

ETA6002E8A 是钰泰(ETA)面向单节锂离子/锂聚合物电池的线性充电管理芯片,采用 ESOP-8 封装。芯片支持从 4.4V 到 5.5V 的输入工作电压,最大充电电流可达 2.5A,充电采用典型的恒流-恒压(CC/CV)策略,充饱和电压为 4.20V。器件工作温度范围宽(-40℃ 至 +85℃),支持电池温度检测与 0V 唤醒充电,静态电流仅 70µA,适合需低待机功耗与较高充电速率的便携式应用。

二、主要规格要点

  • 输入电压(工作):4.4V ~ 5.5V
  • 最大充电电流:2.5A(可编程)
  • 充电饱和电压:4.20V(单节)
  • 适配电池类型:单节锂离子 / 锂聚合物
  • 支持 0V 电池充电(电池深度放电唤醒)
  • 支持电池温度检测(TS 引脚,配 NTC)
  • 静态电流(Iq):70µA
  • 工作温度:-40℃ ~ +85℃
  • 封装:ESOP-8
  • 品牌:ETA(钰泰)

三、功能特性与应用价值

  • 低静态电流:70µA 的待机耗电对要求长待机或电池维护场景非常友好,能减少系统在未充电时的能耗。
  • 支持 0V 唤醒:当电池电压极低时能进行预充电,恢复电池保护电路后进入正常充电,提升系统可靠性。
  • 电池温度检测:通过 TS 引脚配合标准 NTC,可以实现过冷/过热保护,符合电池安全充电规范。
  • 高充电电流能力:最高 2.5A 输出适合中高功率便携设备,实现较快充电速度。
  • 宽输入电压及工业级工作温度,适用车载附件、工业便携终端等对环境适应性要求高的场景。

四、典型应用场景

  • 移动电源(Power Bank)、便携充电器
  • 便携式音箱、移动摄像机、无人机遥控器
  • 工业便携终端、手持仪器、电动工具控制模块(单节电池快速充电)
  • 智能家居与 IoT 设备(需要低待机电流)

五、设计注意事项与建议

  • 输入源稳定性:确保输入 5V 源在 4.4V~5.5V 范围内稳定,USB 供电时建议加足够的输入旁路电容与滤波。
  • 充电电流设定:器件通常需外接电流设定/电流检测电阻以确定恒流值,选择电阻时需参考芯片数据手册中的参考电压/计算公式。
  • 散热考虑:线性充电器在高电流下会有较大功耗(约为 (Vin - Vbat) × Icharge),板级需做好铜箔散热、EN/热关断及热关断布局以避免过热降额。
  • 电池温度监控:推荐使用标准 10k NTC 并按照数据手册设定温度门限,避免在不安全温度范围内充电。
  • 0V 充电策略:若需支持“唤醒”深度放电电池,应按推荐的前充电流与时间设计,以防对电池造成损伤。
  • 布局与旁路:BAT 与 IN 引脚附近放置低 ESR 电容,确保稳压与瞬态响应;地线应做星形或短回路,减少噪声影响。

六、封装与引脚提示

ETA6002E8A 采用 ESOP-8 小型封装,适合商用化 SMT 组装。典型管脚包括 IN/VBUS、BAT、GND、TS、PROG/ILIM、STAT、EN/CE 等(具体引脚命名与功能请以正式数据手册为准),请在设计前参考官方资料完成引脚连线与外围器件选择。

总结:ETA6002E8A 是一款面向单节锂电高效、安全且具备低静态功耗的充电管理芯片,适合需要兼顾充电速度与功耗控制的便携与工业应用。设计时应重点关注散热与电流设定,严格按照数据手册完成温度保护与 0V 唤醒策略,以确保系统长期稳定与电池安全。

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
