WS2813B-MINI-V1 内置IC全彩LED产品概述

一、产品定位与核心价值

WS2813B-MINI-V1是世微半导体(Worldsemi)推出的内置恒流驱动IC的SMD3535封装全彩LED,针对高密度小间距显示、智能可控照明、微型电子状态指示等场景设计,核心优势在于小体积集成、高亮度色彩还原、高速信号传输,可直接通过单总线级联控制,无需额外驱动芯片,大幅简化电路设计与BOM成本。

二、核心技术特性

  1. 内置单总线控制IC:集成恒流驱动与信号解码功能,仅需1根数据线即可实现多灯级联,支持“一灯一线”精准控制,减少外围电路复杂度;
  2. 精准三基色配比:红(R)、绿(G)、蓝(B)峰值波长分别为621nm、520nm、471nm,符合人眼视觉舒适的色彩范围,发光强度R=240mcd、G=870mcd、B=220mcd,色彩饱和度与亮度均衡;
  3. 高速数据传输:支持800Kbit/s数据速率,长距离级联(单总线可带数十至数百灯)仍保持信号稳定,无丢码、延迟问题;
  4. 宽范围PWM调光:2kHz PWM调光频率,覆盖0-100%线性亮度调节,无明显频闪,适配不同场景亮度需求;
  5. 低功耗设计:静态电流仅0.7mA,待机功耗极低,适合电池供电的便携式产品(如智能手环、小型玩具);
  6. 小体积高密度:SMD3535封装(3.5mm×3.5mm×1.5mm),表面贴装工艺兼容自动化生产,可实现小间距(如1mm以下)LED模组排列,提升显示分辨率。

三、关键性能参数明细

类别 参数详情 三基色波长 R:621nm(峰值)、G:520nm、B:471nm 发光强度 R:240mcd、G:870mcd、B:220mcd(典型值) 控制特性 单总线协议、数据速率800Kbit/s、PWM频率2kHz 电气参数 工作电压DC 5V、静态电流≤0.7mA、典型驱动电流20mA 封装尺寸 SMD3535(3.5×3.5×1.5mm) 工作温度 存储:-40℃+85℃;工作:-20℃+60℃ ESD防护 ≥2kV(人体模式)

四、典型应用场景

  1. 小间距LED显示:微型电子屏幕(如智能手表、手环显示)、小型信息公告屏、车载HUD辅助显示;
  2. 智能氛围照明:车载内饰氛围灯、家居情景灯、舞台微型灯效、桌面创意灯组;
  3. 消费电子配件:机械键盘背光、游戏手柄状态灯、蓝牙耳机指示灯、智能音箱呼吸灯;
  4. 玩具与创意产品:可编程玩具灯效(如机器人、无人机状态灯)、DIY创意灯串、小型装饰灯;
  5. 工业控制指示:小型设备状态指示灯、传感器信号显示、仪器仪表背光。

五、封装与可靠性说明

  • SMD3535封装优势:采用耐高温环氧树脂封装,兼容回流焊工艺(符合JEDEC标准温度曲线),焊接可靠性高;小体积可实现高密度排列,适配小型化产品设计;
  • 可靠性设计:内置IC集成ESD防护电路,抗静电能力强;发光芯片采用高亮度GaN基材料,光衰低(1000小时光衰≤5%),长期使用亮度稳定;
  • 散热注意:虽单灯功耗低(典型20mA×5V=0.1W),但高密度级联时需预留适当散热空间,避免局部过热影响寿命。

六、使用注意事项

  1. 电源要求:使用稳定DC 5V电源,电压波动需控制在±0.5V以内,防止过压损坏LED或IC;
  2. 信号传输:级联时数据线长度建议≤5m(单总线),长距离可加终端匹配电阻(100Ω左右),避免信号反射;
  3. 静电防护:生产、焊接、组装过程中需佩戴防静电手环,使用防静电工作台,防止静电击穿IC;
  4. 焊接工艺:回流焊温度峰值≤260℃(持续时间≤10秒),手工焊接温度≤350℃(持续时间≤3秒),避免过温损坏。

WS2813B-MINI-V1通过集成化设计平衡了小体积、高性能与易用性,是小型化智能显示、照明产品的高性价比选择。

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
