Low Voltage Detector with Built-in
Delay Circuit
R3130NxxxA/C, R3131NxxxA/C
OUTLINE
R3130N/R3131N Series are CMOS-based low voltage detector ICs with built-in delay circuit, high
Detector Threshold accuracy and ultra low supply current which can be operated at low voltage.
These ICs can be used as system reset generator, and each of these ICs consists of a voltage ref-
erence, a comparator, resistors for setting voltage detector threshold, an output driver transistor, and
an output delay generator.
Detector threshold is fixed internally with high accuracy and requires no adjustment. When Supply
Voltage crosses a setting detector threshold voltage from a high value to a lower value, this IC generates
reset signal.
R3130N Series output “L” at detection mode, while R3131N Series output “H”.
Further, each of R3130N/R3131N Series embeds an output delay generator, when Supply Voltage
crosses a setting detector threshold voltage from a low value to a higher value, during a setting delay
time which is fixed in the IC, this IC keeps the reset condition.
Output Delay Time can be selected. (Typ. 240ms is standard.)
Two output types, Nch open drain type and CMOS type, are available.
Since the package for these ICs is SOT23-3 (Mini-mold) package, high density mounting of the ICs
on board is possible.

• Output Delay Operation
Output Delay Time, or Tdelay is specified as follows:
1.In the case of Nch open drain output:
The time interval from rising edge of VDD pulse (1.0V→(VDET)+1.0V) to the time at which the output
reaches 2.5V under the condition that the output pin (OUT) is pulled up to 5V through a 470kΩ
resistor.
2.In the case of CMOS output
The time interval from rising edge of VDD pulse (1.0V→(VDET)+1.0V) to the time at which the output
reaches VDD/2.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum Ratings are threshold limit values that must not be exceeded even for a moment
under any conditions.
Moreover, such values for any items must not be reached simultaneously. Operation above these
absolute maximum ratings may cause degradation or permanent damage to the device. These are
just stress ratings and do not necessarily imply to guarantee operation below these limits.

Operating Diagram
In the above diagram,
Output voltage becomes equal to supply voltage (Nch open drain output Type; equal to pull-up
Voltage).
①
① When supply voltage is down to the detector threshold level (Point A), Vref ≥ VDD× Rb/(Ra+Rb) is
true. Then, Output of the comparator is reversed, thus output voltage becomes equal to GND level.
① When supply voltage is lower than minimum operating voltage, output of transistor is indefinite,
therefore output is also indefinite.
① Output voltage is equal to GND level.
① When supply voltage is higher than released voltage (Point B), Vref ≤ VDD× Rb/(Ra+Rb) is true. Then
output of the comparator is reversed, thus output voltage becomes equal to supply voltage (Nch
open drain output type; equal to pull-up voltage).
* There is no hysteresis range between detector threshold and released voltage.

Operation Diagram
In the above diagram,
① Output voltage becomes equal to GND level.
①When supply voltage is down to the detector threshold level (Point A), Vref ≥VDD× Rb/(Ra+Rb) is true.
Then, output of the comparator is reversed, thus output voltage becomes equal to supply voltage
(Nch open drain output type; equal to pull-up Voltage).
① When supply voltage is lower than minimum operating voltage, Output of transistor is indefinite,
therefore output is also indefinite.(Nch open drain output type; Output voltage level is equal to
pull-up voltage.)
① Output voltage is equal to supply voltage. (Nch open drain output type; equal to pull-up voltage.)
① When supply voltage is higher than released voltage (Point B), Vref ≤ VDD× Rb/(Ra+Rb) is true. Then
output of the comparator is reversed, thus output voltage becomes equal to GND level after the
output delay time.
* There is no hysteresis range between detector threshold and released voltage.

Figure A
Figure B
As shown wiring in Figure A and Figure B may cause unstable operation by cross conduction current
at detection of all types of R313xN Series. The detector threshold may shift because of voltage drop by
consumption current of this IC itself.
*At the power-on state, if VDD starts up from minimum input voltage (1V) or less very rapidly, the in-
ternal initialization may not be finished, and output may be unstable. If the transient time from the
minimum input voltage to the detector threshold level at the power-on state is 30µs or less, fully
evaluation is necessary.
