BL55077 是贝岭(BELLING)推出的一款低功耗 LCD 驱动器,封装为 LQFP-64(10×10mm)。器件集成升压电路与内部振荡器,支持 40 段显示与 40×4 bit 的位配置(可驱动多达 160 个 LCD 段位),采用简洁的 2 线串行接口,适合对引脚和功耗有严格要求的便携及工业显示产品。
器件支持 40 段物理驱动并以 40×4 bit 方式组织显示位,适合小至中等规模字符、符号和图标型 LCD 面板。偏压可在 1/3 与 1/2 间切换以平衡对比度和电流消耗;集成升压器可在低电压供电时仍维持足够的 LCD 驱动电压,保证显示对比度。
LQFP-64(10×10mm)表面贴装封装,利于自动化生产与散热。封装引脚数足够实现灵活的控制与扩展,建议 PCB 设计时注意焊盘布局、地平面和热均匀性以确保长期可靠性与良好 EMI 表现。
在最终选型前请核对目标 LCD 面板的段/位数量、面板电容与对比度需求,并参考 BL55077 详细数据手册中的引脚定义、时序、电平与典型应用电路。若系统对功耗或温漂有更苛刻要求,可与厂方或经销商确认器件的典型特性与可靠性验证记录。

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.
