VOLTAGE DETECTOR WITH SENSE PIN
Rev.1.1_00
The S-1002 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed internally with an accuracy of ±1.0% (−VDET(S) ≥ 2.2 V). It operates with current consumption of 500 nA typ. Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even if the SENSE pin falls to 0 V. Two output forms Nch open-drain output and CMOS output are available.
