LTR-507ALS-01 产品概述

一、产品简介

LTR-507ALS-01 是光宝(LITEON)推出的一款微型集成数字光传感器,融合环境光强(ALS)与接近检测(PS)功能,内置LED驱动器,采用无铅芯片式表面贴装封装。器件将光强信息直接转换为通过 I2C 总线读取的数字量,具有宽动态范围内线性响应,适用于高环境亮度场景的光感测与省电唤醒应用。

二、主要技术参数

  • 感测类型:光强(ALS) + 接近(PS)
  • 最大感光能力:64 klx(64,000 lux)
  • 分辨率:11 bit
  • 接口类型:I2C 数字输出
  • 工作电压:2.4 V ~ 3.6 V
  • 静态电流(IQ):约 5 μA(典型)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装尺寸:长 2.65 mm × 宽 2.00 mm × 高 1.30 mm(SMD)
  • 功能特性:低功耗/睡眠模式、事件触发中断、内置温度补偿、光谱校正/滤光、可调增益控制

三、功能亮点

  • 低功耗设计:器件支持睡眠模式与事件驱动中断,使主控无需持续轮询,显著降低系统平均功耗,静态电流仅约 5 μA。
  • 宽动态与线性输出:在大范围环境亮度下保持线性响应,最高可测至 64 klx,适合户外与室内强光场景。
  • 光谱校正与滤光:内建光谱校正机制,优化对人眼感知光强的响应,提升显示亮度/背光控制与自动曝光的准确性。
  • 温度补偿:内置温度补偿功能,减少温度变化对测量精度的影响,提升长期与不同环境条件下的稳定性。
  • 可调增益与接近检测:通过可调增益扩展灵敏度范围,内置接近传感与 LED 驱动可用于近距离唤醒或防误触功能。

四、典型应用场景

  • 智能手机、平板与笔记本屏幕的自动亮度与省电控制
  • 可穿戴设备与 IoT 终端的环境光调整与唤醒检测
  • 摄像头自动曝光参考与光线补偿
  • 智能家居照明与控制系统中的光照测量与场景判断
  • 工业/医疗设备中的环境光监测(在额定温度范围内)

五、系统集成与使用建议

  • 接口:通过主控 MCU 的 I2C 总线读取光强数据,建议在系统设计时保留中断线以启用事件触发模式,从而减少主控唤醒次数与功耗。
  • 电源:器件支持 2.4 V ~ 3.6 V 电源,建议在供电设计上考虑稳压与去耦,确保测量精度与系统抗干扰能力。
  • 光学布局:为保证接收光线的代表性与避免直射强光或遮挡,需在 PCB 布局与传感窗口设计上留出合理的视场角与遮挡保护。
  • 校准:尽管器件内置光谱校正与温度补偿,针对特定应用(如精确照度测量)仍建议结合系统实测进行软件端校准与增益配置。
  • 尺寸与封装:微型 SMD 封装(2.65 × 2.00 × 1.30 mm)便于手机与可穿戴类紧凑设备的系统集成,但需注意焊接工艺与回流曲线以保证可靠性。

六、总结

LTR-507ALS-01 是一款面向便携与嵌入式产品的高集成度数字光传感器,兼具低功耗、宽动态范围与温度/光谱补偿能力,适合需要精确光强感知与低功耗事件驱动的场景。其微型 SMD 封装与 I2C 接口便于在移动设备、消费类电子与智能终端中快速集成与应用。若需更多寄存器、I2C 寄存器映射或参考电路图,请查阅官方数据手册以获得详尽设计指南与应用实例。

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
