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.
