BUILT-IN DELAY CIRCUIT HIGH-PRECISION VOLTAGE DETECTOR

Seiko Instruments Inc.
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-80915AN, detection voltage lies in the range of 1.470
≤
-V
DET
)
≤
1.530.
This means that -V
DET
is 1.470 in a product while -V
DET
is 1.530 in another of the same S-80915AN.
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-80915AN, the release voltage lies in the range of 1.514
≤
(+V
DET
)
≤
1.652. This means that
+V
DET
is 1.514 in a product while +V
DET
is 1.652 in another of the same S-80915AN.
Remark: Although the detection voltage and release voltage overlap in the range of 1.514 V to 1.530 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 11). By giving a device hysteresis, trouble such as noise at the input is avoided.
4.
Delay time (td)
The delay time is a time that the input voltage to
V
DD
terminal exceeds the release voltage (+V
DET
)
and then the output of the OUT terminal inverts.
The delay time can be changed by the additional
external capacitor C
D
