摘要
介绍了微处理器电压监控电路的原理及设计方法。微处理器监控电路在微处理器系统中有效减少了监控系统电源和电池电压所需电路结构的复杂性和数量。与那些分立的集成电路元件和分散的结构相比,这种监控电路芯片对改进系统的可靠性和精确度有重要的意义。以监控门限为4.4V的电路为例对电路设计进行简单的介绍。
To introduce the theory and layout strategy of voltage supervisory circuito The microprocessor supervisory circuits reduce the complexity and number of components required to monitor power- supply and battery functionso These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components.
