Technical Terms
1.
Detection voltage (-V
DET
)
The detection voltage -V
DET
is the voltage at which the output switches to low. This detection voltage varies slightly among
products of the same type. The variation of voltages between the specified minimum [(-V
DET
)min.] and maximum [(-
V
DET
)max.] values is called the detection voltage range (See Figure 5).
Example :
For the S-80808AN, detection voltage lies in the range of 0.784
≤
(-V
DET
)
≤
0.816.
This means that -V
DET
is 0.784 in a product while -V
DET
is 0.816 in another of the same S-80808AN.
2.
Release voltage (+V
DET
)
The release voltage +V
DET
is the voltage at which the output returns (is
“
released
”
) to high. This release voltage varies
slightly among products of the same type. The variation of voltages between the specified minimum [(+V
DET
)min.] and
maximum [(+V
DET
)max.] values is called the release voltage range (See Figure 6).
Example :
For the S-80808AN, the release voltage lies in the range of 0.802
≤
(+V
DET
)
≤
0.867. This means that
+V
DET
is 0.802 in a product while +V
DET
is 0.867 in another of the same S-80808AN.
Remark:
Although the detection voltage and release voltage overlap in the range of 0.802 V to 0.816 V, +V
DET
will
always be larger than -V
DET
.
3.
Hysteresis width (V
HYS
)
The hysteresis width is the voltage difference between the detection voltage and the release voltage
(B-A=V
HYS
in Figure 10). By giving a device hysteresis, trouble such as noise at the input is avoided.
4.
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, and also flows to some extent in Nch open-drain output
devices.
