1.
Detection voltage (-VDET)
The detection voltage -VDET 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 [(-VDET)min.] and maximum [(-
VDET)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 -VDET is 0.784 in a product while -VDET is 0.816 in another of the same S-80808AN.
2.
Release voltage (+VDET)
The release voltage +VDET 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 [(+VDET)min.] and
maximum [(+VDET)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
+VDET is 0.802 in a product while +VDET 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, +VDET will
always be larger than -VDET.
3.
Hysteresis width (VHYS)
The hysteresis width is the voltage difference between the detection voltage and the release voltage
(B-A=VHYS 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.
