The R3112x Series are CMOS-based voltage detector integrated circuits designed with high detector threshold accuracy and ultra-low supply current. They operate at extremely low voltages and include internal components such as a voltage reference unit, comparator, resistor network, output driver, hysteresis circuit, and an output delay circuit. The detector threshold is fixed internally with high accuracy, eliminating the need for external adjustment.
