微处理器复位电路

AiP811/AiP812系列产品是用于检测电源电压并提供复位信号的微控制器复位电路。电路提供硬件复位、上电检测和掉电检测功能。在硬件复位有效时,复位端口始终保持有效状态。在硬件复位结束后,当电源电压低于电路的检测电压时,复位端口保持复位有效状态；当电源电压高于电路的检测电压时,内部定时器将开始工作,延时240ms（典型值）后将复位端口状态改变为复位结束状态。AiP811提供低电平有效的复位信号（RESETN）,并且为推挽输出。AiP812提供高电平有效的复位信号（RESET）,并且为推挽输出。 • 内置上拉电阻且低电平有效的硬件复位端口MRN\n• 上电复位延时时间典型240ms\n• ESD-HBM：4000V\n• 封装形式：SOT23-5/SOT143;
