R3130N/R3131N SERIES
Low Voltage Detector with Built-in Delay Circuit
NO.EA-073-130424
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 reference, 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. (R3131N Series are "Non-promotion")

• 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
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.

In the above diagram,
1 Output voltage becomes equal to supply voltage (Nch open drain output Type; equal to pull-up Voltage).
>
2When 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.
3 When supply voltage is lower than minimum operating voltage, output of transistor is indefinite, therefore
output is also indefinite.
4 Output voltage is equal to GND level.
5 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.

Figure A

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 internal
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.

without prior written consent of Ricoh.
3.Please be sure to take any necessary formalities under relevant laws or regulations before
exporting or otherwise taking out of your country the products or the technical information
described herein.
4.The technical information described in this document shows typical characteristics of and
example application circuits for the products. The release of such information is not to be
construed as a warranty of or a grant of license under Ricoh's or any third party's intellectual
property rights or any other rights.
5.The products listed in this document are intended and designed for use as general electronic
components in standard applications (office equipment, telecommunication equipment,
measuring instruments, consumer electronic products, amusement equipment etc.). Those
customers intending to use a product in an application requiring extreme quality and reliability,
for example, in a highly specific application where the failure or misoperation of the product
could result in human injury or death (aircraft, spacevehicle, nuclear reactor control system,
traffic control system, automotive and transportation equipment, combustion equipment, safety
devices, life support system etc.) should first contact us.
6.We are making our continuous effort to improve the quality and reliability of our products, but
semiconductor products are likely to fail with certain probability. In order to prevent any injury to
persons or damages to property resulting from such failure, customers should be careful enough
to incorporate safety measures in their design, such as redundancy feature, firecontainment
feature and fail-safe feature. We do not assume any liability or responsibility for any loss or
damage arising from misuse or inappropriate use of the products.
7.Anti-radiation design is not implemented in the products described in this document.
8.Please contact Ricoh sales representatives should you have any questions or comments
concerning the products or the technical information.
For the conservation of the global environment, Ricoh is advancing the decrease of the negative environmental impact material.
After Apr. 1, 2006, we will ship out the lead free products only. Thus, all products that will be shipped from now on comply with RoHS Directive.
Basically after Apr. 1, 2012, we will ship out the Power Management ICs of the Halogen Free products only. (Ricoh Halogen Free products are
also Antimony Free.)
