3.3V/5V MicroManager

DS1836微管理器完成三个重要的系统功能。首先，一个精确的温度补偿基准和比较器电路监视VCC电压的状态，当检测到电源超出容差时，器件将产生内部的电源失效信号，强制复位输出处于有效状态。如果VCC电压继续下降，降到低于3.8V (3.3V型号为2.6V)时切换为电池供电。当VCC电压超过3.9V (3.3V型号为2.8V)时，VOUT再次由VCC供电。当VCC返回到容差以内时，复位信号继续保持有效状态350ms。\n最后，DS1836还支持检测输入，无论检测输入电压何时低于1.25V，将发出非屏蔽中断。 ·5V或3.3V上电复位\n·真正的3V工作电源开关\n·在3.8V (3.3V型号为2.6V)时，切换为电池工作\n·尤其适合于设计双电源供电系统\n·电源瞬变期间，复位输出有效\n·在VCC返回容差范围后,复位输出继续保持350ms有效\n·减少分立元件\n·精密的温度补偿电压基准和电压检测\n·8引脚DIP封装或节省空间的8引脚SO表贴封装\n·低电流工作的CMOS复位输出\n·-40°C至+85°C工作温度范围\n·尤其适合于PIC微处理器应用;
