用来监测电源电压或电池电压的微处理器复位电路

CN803/809/810系列电路是用来监测电源电压或电池电压的微处理器复位电路。本系列电路不需要外围器件,从而提高了系统的可靠性，降低了系统的本。本系列电路在被监测的电源电压低于预先设置的复位阈值时，输出有效的复位信号；当电源电压上升到复位阈值以上时，在至少140毫秒的时间内复位信号还将维持有效。CN803提供漏极开路复位输出，CN809/810提供CMOS复位输出。CN803的漏极开路输出需要一个上拉电阻，此电阻可以被连接到VCC或VCC以外的其它电源。CN803/809的复位输出为低有效，CN810的复位输出为高有效。在设计上保证短时间的电源突降不会影响复位输出。在整个温度范围内,当电源 • 精确的复位阈值：±2.5%\r\n• 提供两种复位输出：\r\n• 最小140ms的复位脉冲宽度\r\n• 低工作电流：3V时典型值3.2µA\r\n• 复位信号在电源电压低至1.15V时仍能维持可靠输出\r\n• 对短时间电源突降的过滤功能\r\n• 工作温度范围：－40°C to +85°C\r\n• 采用SOT23-3封装;
