用于微处理的电源和电池电压的监测

CN705/706/707/708/813系列微处理器复位电路主要用于微处理的电源和电池电压的监测。CN705/706/707/708/813系列电路集成有微处理器复位电路、看门狗电路、手动复位电路和一个阈值为1.22伏的电源掉电电压比较器。本系列电路降低了系统的复杂性和外围元器件的数目，提高了系统的可靠性。CN705/706/707/708/813系列微处理器复位电路提供几种功能选择。每个器件都能在电源电压低于复位阈值时产生一个复位信号。此外CN705/706/813 还有一个定时为1.6秒的独立看门狗电路；CN707/708同时提供低有效和高有效的复位信号，但是没有看门狗电路。CN813除 • 复位信号在电源电压低至1.15伏时仍能维持可靠输出\r\n• 精确的电压监测功能，复位阈值从2.6伏到5.0伏，每0.1伏一档\r\n• 低工作电流：5V时典型值52微安\r\n• 复位脉冲宽度典型值200毫秒\r\n• 独立的看门狗电路，定时时间典型值为1.6秒\r\n• 提供电源掉电或者电池电压过低比较器\r\n• 与业界标准的705/706/707/708/813管脚排列、功能兼容\r\n• 8脚双列直插封装（DIP8）和8脚小外形封装（SOP8）;
