WS2812E-2427 产品概述

一、产品简介

WS2812E-2427 是一款由 worldsemi 提供的三色集成光源,内置驱动IC的幻彩灯珠。单点单控(单线数据链式级联)设计,工作电压范围宽(3.7V~5.3V),高性价比、低功耗(典型工作电流 12mA),体积小巧(2.7×2.4×1.1mm),适用于对空间和成本敏感的小型产品,如汽车氛围灯、小家电和机器人等。

二、主要技术参数

  • 波长:R 620–625nm;G 520–525nm;B 449–454nm
  • 发光强度(典型):R 320mcd;G 1000mcd;B 110mcd
  • 工作电压:3.7V ~ 5.3V
  • 工作电流(典型):单色/单点 12mA(全色工作需按实际配置估算)
  • 静态电流:0.6mA
  • PWM 频率:2kHz(亮度调制)
  • 数据速率:800 kbit/s(单线串行协议)
  • 工作温度:-40℃ ~ +65℃
  • 外形尺寸:长 2.7mm × 宽 2.4mm × 高 1.1mm
  • 封装:SMD-4P(四引脚贴片)
  • 功能特性:内置上电复位电路、内置掉电复位电路

三、功能与优势

  • 内置控制IC,支持单线串联控制,级联便捷,减少外部驱动器件数量。
  • 2kHz PWM 提供平滑亮度调节,800kbps 数据速率兼容常见的灯带/像素级控制协议。
  • 上电/掉电复位电路保证启动和关断过程的可靠性,降低异常状态。
  • 小体积、高亮度(尤其绿色通道),适配小型化产品布局与视觉效果需求。
  • 宽电压和宽温度范围,适合汽车与部分工业场景的电源与温度波动。

四、封装与引脚说明

  • 封装形式:SMD-4P,底部/侧面四焊盘。典型引脚功能为 VDD、GND、DIN(数据输入)、DOUT(数据输出)。
  • PCB 布局建议:在每颗灯珠的 VDD 与 GND 旁放置 0.1µF 陶瓷去耦电容;数据线靠近 DIN 端焊盘处可串联 220–470Ω 的缓冲电阻以抑制信号反射;多个灯珠串联时每段建议保持良好地线回流并评估电压跌落。

五、典型应用场景

  • 汽车内饰氛围灯(需考虑车载电源瞬态与抗干扰设计)
  • 桌面/便携小家电的状态指示与装饰照明
  • 服务机器人、玩具与智能硬件的像素化光效
  • 可定制灯带、迷你显示与装饰面板

六、设计注意事项

  • 电源管理:按预计最大点数计算总电流(每点典型 12mA),为整串选择合适的稳压电源与线路尺寸。
  • 电平匹配:若 MCU 输出电平低于 VDD 的有效高电平阈值(例如 MCU 3.3V 而驱动串以 5V),建议使用电平移位器或提高信号强度以保证可靠通信。
  • 热管理:虽然功耗较低,但密集布置和持续高亮时仍需关注热积累,必要时留出散热空间或间隔布局。
  • 抗干扰与保护:车载或工业应用中建议增加输入瞬态保护、滤波及适当保险元件,防止电压尖峰影响内置IC。
  • 焊接工艺:遵循通用无铅回流曲线与封装厂商推荐的焊接参数,避免过热导致封装或内部IC损伤。

七、订购与规格确认

型号:WS2812E-2427
品牌:worldsemi
封装:SMD-4P,尺寸 2.7 × 2.4 × 1.1 mm
如需样片、批量采购或更详细的器件规范书(包含完整电气特性曲线、时序图、参考PCB封装与回流曲线),建议联系供应商或索取 Datasheet 进行确认,便于在具体项目中完成可靠性与一致性验证。

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
