LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
R3112xxx1A/C Series
2001. Apr. 4
Rev. 1.10 - 1 -
I
OUTLINE
The R3112 Series are voltage detector ICs with high detector threshold accuracy and ultra-low
supply current by CMOS process, which can be operated at an extremely low voltage and is used for
system reset as an example.
Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector
threshold setting, 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.
Two types of packages, SOT-23-5 and ultra small SC-82AB can be selected so that high density
mounting on boards is possible.
