3. Delay time (t
4. Through-type current
The hysteresis width is the voltage difference between the detection voltage and the release voltage.
The existence of the hysteresis width prevents malfunction caused by noise on the input voltage.
The through-type current refers to the current that flows instantaneously when the voltage detector
detects and releases a voltage. The through-type current flows at a frequency of 20 kHz during the
release delay time since the internal logic circuit operates.
The delay time is a time internally measured from the instant at which the voltage input to the VDD pin
exceeds the release voltage (+V
