Worldsemi(世界半导体)推出的WS2814C是一款4通道集成式LED驱动控制芯片,专为小功率LED照明、指示及显示场景设计,集成PWM调光功能,具备宽电压兼容、工业级温宽等核心特性,可有效简化电路设计并提升LED应用的稳定性。
WS2814C定位于中小功率多通道LED驱动,单芯片可同时驱动4路独立LED,无需额外添加调光控制单元,适用于对成本、体积敏感的消费电子、工业设备及户外小型应用场景。其核心是在紧凑封装内实现“驱动+调光”一体化,减少外围元件数量,降低PCB布局复杂度。
WS2814C的核心参数覆盖电源、驱动、调光及环境适应性,具体如下:
WS2814C采用8引脚小型贴片封装(SOP-8),体积紧凑(封装尺寸:5.2mm×4.0mm×1.5mm),便于自动化贴装,引脚功能清晰易识别:
引脚编号 引脚名称 功能说明 1 VDD 3.7V~5.3V直流电源输入 2 GND 电源地(需可靠接地,避免虚焊) 3 CH1 第1路LED驱动输出 4 CH2 第2路LED驱动输出 5 CH3 第3路LED驱动输出 6 CH4 第4路LED驱动输出 7 PWM PWM调光信号输入(TTL电平兼容) 8 NC 空脚(可悬空或接地,不影响功能)WS2814C因体积小、集成度高、温宽宽,广泛应用于以下场景:
WS2814C针对恶劣环境做了可靠性优化:
为确保WS2814C稳定工作,需注意以下细节:
综上,WS2814C以“高集成度、宽电压、工业级温宽”为核心优势,是小功率多通道LED应用的高性价比选择,可满足消费电子、工业设备等多领域的设计需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
