3. Hysteresis width (V_HYS)
The hysteresis width is the voltage difference between the detection voltage and the release voltage (the voltage at
point B − the voltage at point A = V_HYS in Figure 25, Figure 27, Figure 33 and Figure 35). Setting the hysteresis
width between the detection voltage and the release voltage, prevents malfunction caused by noise on the input
voltage.
4. Feed-through current
The feed-through current is a current that flows instantaneously to the VDD pin at the time of detection and release
of a voltage detector.
