R3117xxx3/4 SERIES LOW VOLTAGE DETECTOR with SENSE pin
The Ricoh R3117x series are CMOS-based voltage detector ICs featuring high threshold accuracy and ultra-low supply current. They operate at extremely low voltages (1.0V to 6.0V) and are suitable for applications such as system reset, battery checking, and power failure detection. The devices include a voltage reference unit, comparator, resistors for threshold setting, an output driver, and a hysteresis circuit.
