Remark Although the detection voltage and release voltage overlap in the range of 2.725 V to 2.754 V,
+VDET is always larger than VDET.
2. Hysteresis Width (VHYS)
Hysteresis width is the voltage difference between the detection voltage and the release voltage (The
voltage at point B
The voltage at point A=VHYS in Figure 15). The existence of the hysteresis width avoids
malfunction caused by noise on input signal.
3. Delay Time (tD)
Delay time is a time internally measured from the instant at which input voltage to the VDD pin exceeds
the release voltage (
+VDET) to the point at which the output of the OUT pin inverts. The delay time
changes according to the external capacitor (CD).

4. 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, and small in Nch
open-drain output products.
