R3111x SERIES  
LOW VOLTAGE DETECTOR  
OUTLINE  
NO.EA-056-130722  
The R3111x series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low  
supply current, 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.  
Three output types, Nch open drain “L” type, Nch open drain “H” type and CMOS type are available.  
The R3111x Series are operable at a lower voltage than that for the Rx5VL series, and can be driven by a  
single battery.  
Seven types of packages, TO-92 (Discontinued), SOT-89, SOT-23-3, SOT-23-5, SC-82AB, SC-88A and  
SON1612-6 are available.

ABSOLUTE MAXIMUM RATINGS  
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the  
permanent damages and may degrade the life time and safety for both device and system using the device  
in the field. The functional operation at or over these absolute maximum ratings is not assured.  
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)  
All of electronic equipment should be designed that the mounted semiconductor devices operate within the  
recommended operating conditions. The semiconductor devices cannot operate normally over the  
recommended operating conditions, even if when they are used over such conditions by momentary  
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue  
to operate over the recommended operating conditions.

DEFINITION OF OUTPUT DELAY TIME  
Output Delay Time (tPLH) is defined as follows:  
1. In the case of Nch Open Drain Output:(R3111xxxxA/B)  
Under the condition of the output pin (OUT) is pulled up through a resistor of 470kΩ to 5V, the time interval  
between the rising edge of VDD pulse from 0.7V to (+VDET)+2.0V and becoming of the output voltage to 2.5V.  
2. In the case of CMOS Output:(R3111xxxxC)  
The time interval between the rising edge of VDD pulse from 0.7V to (+VDET)+2.0V and becoming of the output  
voltage to ((+VDET)+2.0V)/2.

a detector threshold voltage (−VDET).  
Step 3. When the supply voltage is lower than the minimum operating voltage, the operation of the output  
transistor becomes indefinite. The output voltage is equal to the pull-up voltage.  
Step 4. The output Voltage is equal to the GND level.

Step 5. At Point “B”, Vref VDD×Rb/(Ra+Rb) is true, as a result, the output of comparator is reversed from "L" to

TECHNICAL NOTES  
When R3111xxxxA/B (Nch Open Drain Output Type) is used in Figure A or Figure B, if impedance of Voltage  
Supply pin, VDD and VDD of this IC is large, detector threshold level would shift by voltage dropdown caused by  
the consumption current of the IC itself. Released voltage may also shift and delay time for start-up might be  
generated by this usage.  
When R3111xxxxC (CMOS Output Type) is used in Figure A or Figure B, Output level could be unstable by  
cross conduction current which is generated at detector threshold level or at released voltage level, therefore, do  
not use this IC with the connection in Figure A or Figure B.  
The connection in Figure C may cause the oscillation in both R3111xxxxC (CMOS Output) and R3111xxxxA/B  
(Nch Open Drain Output), therefore do not use R3111x Series with the connection in Figure C.
