5. Through-type current
Through-type current refers to the current which flows instantaneously, at the time of detection and release of a
voltage detector. Through-type current is large in CMOS output devices.
6. Oscillation
In applications where a resistor is connected to the voltage detector input , in the CMOS active low products for
example, 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 resultant input voltage drops
below the detection voltage -V
DET
, 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. A through-type current
is again generated, a voltage drop appears, and the process repeats. This unstable condition is referred to as
oscillation.
