R3111x SERIES

LOW VOLTAGE DETECTOR

NO.EA-056-130722

1

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 (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.

Step 1. The output voltage is equal to the pull-up voltage.

>

=

Step 2. At Point “A”, Vref VDD (Rb Rc)/(Ra Rb× + + +Rc) 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

VDD Rb/(Ra× +Rb) 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.

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.
