CXLE8747闪光灯手电筒LED驱动器为前摄像头闪光灯和小电流后摄像头闪光灯应用而设计闪光超时保护电流通过RSET引脚和GND之间连接的外部电阻进行调节或RSET引脚连接到GND来设置为默认200毫安

CXLE8747是一款低成本闪光灯/手电筒LED驱动器，专为前摄像头闪光灯和小电流后摄像头闪光灯应用而设计。
CXLE8747集成了一个电流接收器，以确保在诸如VBAT电压、LED VF电压、环境温度变化等条件下LED电流恒定。LED电流可以通过RSET引脚和GND之间连接的外部电阻进行调节，也可以通过简单地将RSET引脚连接到GND来设置为默认200毫安。
CXLE8747具有闪光超时保护功能，防止LED灯在异常情况下过热。
输入电压范围：2.7~5.5V
最大可配置ILED:200mA
l ILED精度：+/-20%
闪光超时保护
过温保护

一.产品概述

---

    CXLE8747 is a low cost Flash/Torch LED driver designed for front camera flash and small current rear camera flash application. 

    CXLE8747 integrates a current sink to ensure constant LED current when conditions such as VBAT voltage, LED VF voltage, ambient temperature change. The LED current can be adjusted by external resistor connected between RSET pin and GND, and also can be set to default 200mA by just simply connect RSET pin to GND. 

    CXLE8747 has flash time-out protection function to prevent LED lamp from overheating in abnormal conditions.
