ET6226M 产品概述

一、产品简介

ET6226M 是 UMW(友台半导体)推出的一款用于 LED 数码管显示的驱动器,采用 SOP-16 封装,集成驱动与键盘扫描功能。器件支持 8 段 × 4 位的显示配置,适用于各类需要多位数码显示且接口引脚受限的便携设备与家电控制面板。工作电压范围宽(3.0V~5.5V),能够兼容 3V 到 5V 的系统电源。

二、主要电气特性

  • 接口类型:2 线串行接口,便于与微控制器连接,占用引脚少,通信实现简单。
  • 静态电流:典型值约 300 μA,适合低功耗待机应用。
  • 位驱动电流:最高可达 150 mA(位驱动),用于驱动数码管位选端。
  • 段驱动电流:每段驱动可达 25 mA,支持较高亮度的 LED 显示。
  • 工作温度:-40 ℃ 至 +85 ℃,满足工业级温度要求。

三、功能亮点

  • 键盘扫描:内置键盘扫描功能,能够直接扫面并识别按键,减少外部独立键控电路设计。
  • 辉光可调:支持亮度调节(辉光可调),可通过串行接口调整显示亮度以适应不同照明环境或节能需求。
  • 低引脚数:2 线串行接口与 SOP-16 封装使其在空间与引脚资源受限的系统中具有很强的集成优势。

四、应用场景

ET6226M 非常适合用于家庭电器控制面板、便携式仪表、电子秤、医疗仪器前面板、车载仪表显示及其他需要 4 位 LED 数码显示并带键盘输入的嵌入式设备。

五、设计与注意事项

  • LED 限流:建议为每段 LED 配置合适的限流电阻或在系统层面控制段电流,以控制实际亮度并保护 LED。
  • 电源与去耦:推荐在 VCC 端添加 0.1 μF 陶瓷电容进行去耦,抑制瞬态干扰,保证串行通信稳定。
  • 功耗管理:在高亮度或多段同时点亮时,位/段驱动电流累积会显著增加瞬态电流,设计时需注意电源能力与 PCB 散热。
  • 接口兼容:2 线串行接口与多数 MCU 易于对接,但在系统设计中应注意信号电平(工作电压范围内),必要时采用电平转换电路。
  • 环境适应:器件支持 -40~+85 ℃ 工况,适用于工业与商用环境,但在极端高功耗状态下需关注封装温升。

六、小结

ET6226M 以其紧凑 SOP-16 封装、低静态电流、大驱动能力、键盘扫描与可调亮度等特性,为需要多位 LED 显示与键盘输入的产品提供了高集成度、低外部元件需求的解决方案。其宽工作电压与工业级温度范围使其在多种应用场景中具备良好的适用性。若需进一步引脚定义、电气时序或参考电路图,建议查阅厂方完整资料或联系 UMW 技术支持获取详细数据手册。

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
