supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high
accuracy internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type
are available.
density mounting on boards is possible.
FEATURES
APPLICATIONS
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
The R3112x Series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low
Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting,
Three types of packages, SOT-23-5, small SC-82AB, and ultra-small SON1612-6 can be selected so that high
