SCS5090EA 充电芯片产品概述
一、核心定位与目标应用
SCS5090EA是杰盛微（JSMSEMI）针对2节串联锂电池开发的专用充电芯片，聚焦「小体积、宽温、快充」三大核心需求，适配便携式、工业级等多场景设备。典型应用包括：
- 便携式储能电源（2节锂电容量10000mAh20000mAh，1.8A充电可实现35小时满电）；
- 户外照明设备（露营灯、应急灯，支持-40℃低温环境稳定充电）；
- 小型电动工具（电动螺丝刀、迷你电钻，满足现场快充补电需求）；
- 工业手持终端（巡检仪、数据采集器，宽温环境下持续可靠工作）。
二、关键性能参数解析
芯片核心参数精准匹配2节锂电池（标称7.4V、满电8.4V）的充电需求，具体如下：
- 工作电压范围：3.6V~6V
兼容主流输入源（5V USB充电器、单节锂电池3.7V、低压太阳能板），无需额外升压/降压电路，简化系统设计； - 最大充电电流：1.8A
支持快充模式，相比传统1A充电速度提升80%，解决用户「慢充痛点」； - 充电饱和电压：8.5V
充电后期自动切换至恒压模式，精准匹配电池满电状态，避免过充导致的电池寿命缩短； - 电池温度检测：内置NTC接口
实时监测电池温度，过温（>60℃）/欠温（<0℃）时自动停止充电，防止热失控或低温充电损坏； - 工作温度范围：-40℃~+85℃
覆盖工业级宽温要求，可在极端环境（北方冬季户外、南方夏季车间）稳定工作，无需额外散热组件。
三、封装与环境适应性
采用ESOP-8封装，兼具小体积与可靠性，适合紧凑设备集成：
- 体积紧凑：封装尺寸（5.0mm×6.0mm）可嵌入手持终端、迷你储能电源等空间受限场景；
- 散热优化：外露散热焊盘配合PCB铜箔，可有效导出1.8A充电时的热量，避免芯片过热；
- 环保与抗干扰：符合RoHS标准，引脚抗腐蚀性能优异，可适应潮湿、多尘的工业环境。
四、安全防护特性
内置多重安全机制，从输入到电池全链路防护：
- 过充保护：电池电压达8.5V时自动关断充电，防止膨胀；
- 过流保护：电流超1.8A时限流至1.5A，避免芯片/电池损坏；
- 输入过压保护：输入电压超6V（如7V）时切断输入，保护后端电路；
- 电池反接保护：极性接反时不工作，防止短路烧毁。
五、设计与应用注意事项
为确保稳定工作，需关注以下细节：
- 输入滤波：输入引脚串联10Ω~22Ω限流电阻，并联10μF陶瓷电容，滤除纹波；
- 温度检测：外接10kΩ/25℃ NTC，靠近电池放置，提升温度监测精准度；
- 散热布局：ESOP-8散热焊盘下增加2~3层铜箔（面积≥10mm×10mm），强化散热；
- 输出匹配：输出端串联1μF陶瓷电容、并联100μF电解电容，降低充电纹波对电池的影响。
SCS5090EA凭借宽温、快充、小体积与多重安全防护，成为2节锂电池设备的高性价比充电解决方案，适合对成本、体积、可靠性有严格要求的应用场景。

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.
