R3112x SERIES
LOW VOLTAGE DETECTOR WITH OUTPUT DELAY
NO. EA-087-090422
1
OUTLINE
The R3112x Series are CMOS-based volt age detect or ICs with high detector threshold a ccuracy 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 consi sts of a voltage referen ce unit, a comp arator, resistor net for d etector threshold settin g,
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.

RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment sho uld b e designed that the mounted semiconductor device s o perate 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 su rge. And the semicondu ctor devices may receive seriou s damage when they continu e
to operate over the recommended operating conditions.

1. Output voltage is equal to sup ply voltage. (As for Nch open drain type, equal to pull-up volta ge.)
2. When the supply voltage i s do wn to the detector threshold voltage level(Point A),
Vref
>
=
VDD×(Rb+Rc)/(Ra+Rb+Rc) is true, then output of the comparato r is reversed f rom “L” to “H”, therefore
output voltage becomes G ND 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 volt age.
4. Output Voltage becomes G ND level.
5. When the supply voltage is higher than released voltage (Point B), Vref
<
=
VDD×Rb/(Ra+Rb) 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.

Supply Voltage
When the supply voltage which is higher than released voltage is forced to VDD pin, charge to an external
capacitor st ar t s, then cap acitor voltage increa ses. Until the ca p acitor volt age rea ches to CD Pin thre shold v olt age,
output voltage maintains “L”. When the capacitor voltage becomes higher than CD pin threshold voltage, output
voltage is rev ersed from "L” to "H". Where, the time interval betwee n the rising edge of supply volt age and output
voltage reverse poi nt means output delay time.
Output Dela y Time
Output Delay Time (tD) can be calculated with the next formula.
tD=0.69×RD×CD(s)
RD is internal resistor and set at 6.5MΩ(Typ.) typically. CD(F) describes the capacitance value of an external
capacitor. Therefore,
tD=0.69×6.5×106×CD(s)
