■ OUTLINE
The R3111 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,
resistors for detector threshold setting, an output driver and a hysteresis
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.
■ FEATURES
● Ultra-low Supply
Current...............................................TYP.0.8µA (VDD=1.5V)
● Wide Range of Operating Voltage....................................... 0.7
to 10.0V(Topt=25°C)
● Detector Threshold....................... Stepwise setting with a step of
0.1V in the range of
0.9V to 6.0V is possible.
● High Accuracy Detector Threshold...................................... ±2.0%
● Low Temperature-Drift Coefficient of Detector Threshold............ TYP.
±100ppm/°C
● Two Output Types .......................................... Nch Open Drain
and CMOS
● Four Types of Packages...... TO-92, SOT-89(Mini-power Mold), SOT-23-5 (Mini
mold), SC-82AB
■ APPLICATIONS
● CPU and Logic Circuit Reset
● Battery Checker
● Window Comparator
● Wave Shaping Circuit
● Battery Back-up Circuit
● Power Failure Detector
