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.

*1. −VDET: Actual detection voltage value, −VDET(S): Set detection voltage value
*2. Hysteresis width is "unavailable", so release voltage = detection voltage.
*3. The current flowing through the SENSE pin resistance is not included.
*4. VDS: Drain-to-source voltage of the output transistor
*5. The time period from when the pulse voltage of −VDET(S) + 0.5 V → −VDET(S) − 0.5 V is applied to the SENSE pin to
when VOUT reaches VDD / 2, after voltage of 16.0 V is applied to the VDD pin and the SENSE pin input voltage (VSENSE)
reaches the release voltage once.
*6. The time period from when voltage of 16.0 V is applied to the VDD pin and the pulse voltage of −VDET(S) − 0.5 V →
−VDET(S) + 0.5 V is applied to the SENSE pin to when VOUT reaches VDD / 2.
