2. Hysteresis Width (V
HYS
)
Figure 20 Release Voltage (CMOS Output Products)
The hysteresis width is the voltage difference between the detection voltage and the release voltage (The

in
Figure 16
). The existence of the hysteresis width
prevents malfunction caused by noise on input signal.
3. Through-type Current
The through-type current refers to the current that flows instantaneously at the time of detection and release
of a voltage detector. The through-type current is large in CMOS output products, small in Nch open-drain
output products.
4. Oscillation
In applications where a resistor is connected to the voltage detector input (
Figure 13
), 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
DET
) as a result, the output voltage goes to low level.
In this state, the through-type current stops and its resultant voltage drop disappears, and the output goes
from low to high. A through-type current is again generated, a voltage drop appears, and repeating the
process finally induces oscillation.
