CXDR75107内部计时器延迟输出返回到非活动状态，以确保系统正确复位。延迟时间td在VCC上升到阈值电压VIT+以上后开始。当电源电压降到阈值电压VIT-（2）以下时，输出再次激活。不需要外部组件。所有器件都有一个由内部分压器设置的固定感应阈值电压VIT。CXDR75107包含一个手动复位输入MR。MR处的低电平导致RESET（RESET）激活。产品频谱设计用于2.5V、3V、3.3V和5V的电源电压。这些电路以SOT-23-5封装提供。CXDR75107主要为基于DSP和处理器的系统提供电路初始化和时序监控。在通电期间，当电源电压VCC高于1.1 V时，将断言复位（重置）。此后，电源电压监管器监控VCC，并在VCC保持在阈值电压以下时保持复位（重置）激活
