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
voltage at point B
The voltage at point A
=
V
HYS
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.
