ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
In applications where a resistor is connected to the voltage detector input (Figure 22), taking a CMOS
active low product for example, the through-type current, which is generated when the output goes from
low to high (release) causes a voltage drop equal to [through-type current] × [input resistance] across the
resistor. When the input voltage drops below the detection voltage (−V
goes to low level. In this state, the through-type current stops and its resultant voltage drop disappears,
