LP28057ASPF 是 LOWPOWER(微源半导体)面向单节锂离子电池的充电管理芯片,封装为 ESOP-8。芯片输入工作电压范围为 4.5V ~ 6.5V,最大充电电流可达 1A,充电饱和电压(终止电压)为 4.2V。器件支持电池温度检测功能,适用于需要精确温度保护和低静态电流的便携设备与智能终端。工作温度范围 -20℃ ~ +85℃,静态电流仅 1μA,适合要求长待机和低漏电的应用场合。
ESOP-8 封装兼顾封装密度与散热性能,布板时注意暴露焊盘或增加散热铜箔以提升热流散能力。器件工业级温度范围使其适合多种环境应用,但在高温或高功率工作点应做热仿真与可靠性验证。
如需原理图参考、典型应用电路或完整电气规格(引脚定义、时序、编程方法等),建议下载 LOWPOWER 官方数据手册或联系厂家技术支持获取详细资料与评估板。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
