LP28056SPF 为 LOWPOWER(微源半导体)面向单节锂离子电池充电管理的高性能充电芯片。器件支持工作电压范围 4.5V 至 6.5V,最大充电电流可达 1.2A,充电终止电压(饱和电压)为 4.2V,静态电流极低仅为 1μA,适用于对待机能耗要求苛刻且需可靠充电管理的便携设备与物联网终端。器件封装为 ESOP-8,工作温度范围宽 (-40℃ ~ +85℃),便于工业级与民用级产品设计。
LP28056SPF 采用 ESOP-8 封装,便于焊接与热传导。对于持续高电流工作场景,建议在 PCB 下方和周围布局充足的铜箔和过孔形成散热通道,以降低结温并保证长期可靠性。设计时应参考实际功耗评估结温并预留足够的热裕度。
LP28056SPF 以其宽输入电压、1.2A 的充电能力、4.2V 的充电终止电压及超低 1μA 静态电流,适合对能耗敏感、要求可靠单节锂电池充电管理的便携与嵌入式产品。设计时需重视热管理与合理的外围元件选型,结合良好 PCB 布局可获得稳定、高效的充电性能。若需进一步的电气参数、引脚定义或典型应用电路图,建议参考器件的详细数据手册或联系 LOWPOWER(微源半导体)获得完整设计资料。

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.
