描述
BD4269UEFJ-C是一款45V高耐压稳压器,内置用来监控IC输出电压下降的复位电路,以及用来监控IC输入电源电压或其他电源电压下降的复位电路。本产品的静态电流非常低,适合用来进一步降低系统的消耗电流。输出低电压复位和电源电压检测复位功能可通过外置电阻器来调整检测电压。另外,复位信号的恢复延迟时间可以通过外置电容器进行调整。本系列产品中的BD4269EFJ-C是为提高生产效率而变更生产线后的型号。在新项目选型时,建议选择该型号。另外,在技术规格书中的保证特性并没有差异。除非另有说明,否则我们还会披露文档和设计模型的 BD4269EFJ-CE2 数据。

General Description  
Key Specifications  
BD4269FJ-C BD4269EFJ-C are a low quiescent  
voltage regulator with 45V absolute maximum voltage  
allowing usage in battery direct-connected systems. IC  
integrates Power on and under-voltage reset and Input  
voltage reset for VCC or other voltages. Quiescent  
current is minimized to optimize the system current  
consumption. Offers selection of the output current  
between 200 mA or 300 mA depending on the  
application.
