OUTLINE
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, 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 470k 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.

Operation Diagram
Explanation of operation
Step 1. The output voltage is equal to the pull-up voltage.
Step 2. At Point “A”, Vref
VDD(RbRc)/(RaRbRc) is true, as a result, the output of comparator is reversed
from "H" to "L", therefore the output voltage becomes the GND level. The voltage level of Point A means
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
VDDRb/(RaRb) is true, as a result, the output of comparator is reversed from "L" to
"H", then the output voltage is equal to the pull-up voltage. The voltage level of Point B means a released
voltage (VDET).
) The difference between a released voltage and a detector threshold voltage is a detector threshold hysteresis.

Power Dissipation (SOT-23-3)
Power Dissipation (PD) depends on conditions of mounting on board. This specification is based on the
measurement at the condition below:
(Power Dissipation (SOT-23-3) is substitution of SOT-23-6.)
Measurement Conditions
Standard Test Land Pattern
Environment Mounting on Board (Wind velocity=0m/s)
Board Material Glass cloth epoxy plastic (Double sided)
Board Dimensions 40mm 40mm 1.6mm
Copper Ratio Top side: Approx. 50%, Back side: Approx. 50%
Through-holes 0.5mm 44pcs
Measurement Result (Ta=25C, Tjmax=125C)
Standard Land Pattern Free Air
Power Dissipation 420mW 250mW
Thermal Resistance ja = (125-25C)/0.42W = 238C/W 400C/W

TECHNICAL NOTES
When connecting resistors to the device’s input pin
When connecting a resistor (R1) to an input of this device, the input voltage decreases by [Device’s
Consumption Current] x [Resistance Value] only. And, the cross conduction current*1, which occurs when
changing from the detecting state to the release state, is decreased the input voltage by [Cross Conduction
Current] x [Resistance Value] only. And then, this device will enter the re-detecting state if the input voltage
reduction is larger than the difference between the detector voltage and the released voltage.
When the input resistance value is large and the VDD is gone up at mildly in the vicinity of the released voltage,
repeating the above operation may result in the occurrence of output.
As shown in Figure A/B, set R1 to become 100 kΩ or less as a guide, and connect CIN of 0.1 μF and more to
between the input pin and GND. Besides, make evaluations including temperature properties under the actual
usage condition, with using the evaluation board like this way. As a result, make sure that the cross conduction
current has no problem.
