36 V, SENSE-Input Voltage Detector with Delay Function (External Delay Time Setting) S-1011 Series

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.
