Low Voltage Detector with built-in
Delay Circuit
R3130N×××A/C, R3131N×××A/C
OUTLINE
R3130N/R3131N Series are low voltage detector ICs with built-in delay circuit, high Detector Threshold accuracy
and ultra low supply current by CMOS process, 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 com-
parator, 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 are 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)+0.1V) 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)+0.1V) 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 con-
ditions.
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 neces-
sarily imply to guarantee operation below these limits.

As shown wiring in Figure A and Figure B may cause unstable operation by through-type current at detection of all
types of R313×N Series. And Detector Threshold may shift because of voltage drop by consumption current of this
IC itself.
