HIGH-WITHSTAND VOLTAGE
BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING) VOLTAGE DETECTOR
Rev.1.2_00
The S-1011 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed
internally, and the accuracy of the S-1011 Series A / C / E / G type is ±1.5%. It operates with current consumption of
600 nA typ.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared in the SENSE detection
product, so the output is stable even if the SENSE pin falls to 0 V.
The detection signal and release signal can be delayed by setting a capacitor externally, and the detection delay time
accuracy is ±20% (CN = 3.3 nF, Ta = +25°C), the release delay time accuracy is ±20% (CP = 3.3 nF, Ta = +25°C).
Output form is Nch open-drain output.

3. Hysteresis width (VHYS)
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 = VHYS in Figure 24 and Figure 28). 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.
