Siproin SSP4056HEP8BG 单节锂电池充电芯片产品概述

一、核心定位与适用场景

SSP4056HEP8BG是上海矽朋(Siproin)推出的一款单节锂电池专用充电管理芯片,主打「宽电压兼容、低功耗待机、工业级宽温可靠性」三大核心优势,适配主流便携设备及严苛环境下的锂电池充电需求,是消费电子、物联网终端、户外储能等领域的高性价比选择。

二、关键性能参数解析

1. 宽电压输入覆盖

支持3.8V~25V输入电压,兼容5V USB、9V/12V适配器、24V车载电源等常见供电场景,无需额外电压转换电路即可适配多类型输入源,简化系统设计流程。

2. 精准充电控制

最大充电电流1A,适配单节锂电池(3.7V/4.2V标称)的常规充电需求;采用恒流(CC)+恒压(CV) 经典充电模式,保证电池充电效率与循环寿命。

3. 工业级宽温适应

工作温度范围-40℃~+85℃,满足户外低温(如冬季户外设备)、高温(如夏季车载/密闭设备)等严苛环境的稳定运行,可靠性优于普通消费级芯片。

4. 极低待机功耗

静态电流(Iq)仅6uA,在电池供电的待机场景(如TWS充电盒未插电时),可最大程度减少电池自放电损耗,延长设备待机时长。

5. 电池温度安全监测

内置电池温度检测引脚,通过外接NTC热敏电阻实时监测电池温度,实现高温降流/停充、低温禁止充电,避免电池过温老化或低温充电损坏,提升充电安全性。

三、核心功能与设计优势

1. 集成多重安全保护

除电池温度检测外,芯片集成过充保护(CV模式电压锁存)、过流保护(充电电流限制)、短路保护等基础安全功能,全流程保障电池与系统安全。

2. 简化系统设计

采用ESOP-8小封装(尺寸约5mm×6mm),集成度高;外围仅需少量电阻、电容及NTC即可实现完整充电功能,无需复杂辅助电路,降低BOM成本与PCB空间占用。

3. 稳定充电曲线

恒流阶段电流稳定,恒压阶段电压精度达±1%以内,避免电池过充或欠充,有效延长锂电池循环寿命。

四、封装与可靠性

SSP4056HEP8BG采用ESOP-8封装,散热性能优于普通SOP封装,适合小型化设备集成;上海矽朋作为国内专注电源管理芯片的厂商,该芯片经过高低温循环、ESD抗扰度、寿命测试等多轮可靠性验证,符合工业级产品质量标准。

五、典型应用场景

  1. 便携消费电子:TWS蓝牙耳机充电盒、蓝牙音箱、智能手环/手表、便携充电宝等小型设备,满足低功耗待机与宽电压输入需求。
  2. 物联网终端:低功耗传感器节点、智能门锁、智能家居控制器等,适配电池供电的长期待机场景。
  3. 户外与工业设备:户外应急灯、便携储能电源、车载小电器(如行车记录仪备用电池)等,适应宽温环境与车载24V电源输入。
  4. 小型储能产品:18650/21700单节锂电池组成的应急电源、太阳能小系统等,兼容低电压(3.8V)太阳能输入。

SSP4056HEP8BG凭借宽电压、低功耗、工业级宽温及高集成度等优势,为单节锂电池充电场景提供了高性价比的解决方案,适合对成本、体积、可靠性有综合要求的应用。

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
