R3112x SERIES
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-087-160310
1
OUTLINE
The R3112x 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, 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.
Three types of packages, SOT-23-5, small SC-82AB, SC-88A and ultra-small SON1612-6 can be selected so
that high density mounting on boards is possible.

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.

1. Output voltage is equal to supply voltage. (As for Nch open drain type, equal to pull-up voltage.)
2. When the supply voltage is down to the detector threshold voltage level(Point A),
VrefV
DD(RbRc)/(RaRbRc) is true, then output of the comparator is reversed from "L" to "H", therefore
output voltage becomes GND level.
3. When the supply voltage is lower than minimum operating voltage, the operation of output transistor is
indefinite. In the case of Nch open drain type, output voltage is equal to pull-up voltage.
4. Output Voltage becomes GND level.
5. When the supply voltage is higher than released voltage (Point B), VrefV
DDRb/(RaRb) is true, then
output of the comparator reaches the threshold level, and Output of Shmitt Trigger is reversed from "H" to
"L", then output voltage is equal to supply voltage. (As for Nch open drain type, equal to pull-up voltage.)
) The difference between released voltage and detector threshold voltage means hysteresis range voltage.

Capacitor Voltage
Supply Voltage
When the supply voltage which is higher than released voltage is forced to VDD pin, charge to an external
capacitor starts, then capacitor voltage increases. Until the capacitor voltage reaches to CD Pin threshold voltage,
output voltage maintains "L". When the capacitor voltage becomes higher than CD pin threshold voltage, output
voltage is reversed from "L" to "H". Where, the time interval between the rising edge of supply voltage and output
voltage reverse point means output delay time.
Output Delay Time
Output Delay Time (tD) can be calculated with the next formula.
tD0.69RDCD(s)
RD is internal resistor and set at 6.5M(Typ.) typically. CD(F) describes the capacitance value of an external
capacitor. Therefore,
