5. Oscillation
In applications where a resistor is connected to the voltage detector input (Figure 11 and 12), the through-type current
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 resultantly drops below the detection voltage -VDET, the output
voltage returns to its low level. In this state, the through-type current -- and its resultant voltage drop -- have disappeared,
and the output goes back from low to high. Again, a through-type current is generated, a voltage drop appears, and the
process repeats. Oscillation refers to this unstable condition
.
