R3116x-Y Series
0.8% Low Voltage Detector with Output Delay for High Temperature Applications
NO.EA-347-140819
OUTLINE
The R3116x is a CMOS-based voltage detector IC 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.
This IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output
driver, a hysteresis circuit and an output delay circuit. The detector threshold is internally fixed with high accuracy
and does not require any adjustment.
Two output types, Nch open drain type and CMOS type are available.
R3116x is offered in a 5-pin SOT-23-5 package and an ultra-small 4-pin DFN(PLP)1010-4 package which can
achieve the smallest possible footprint solution on boards where area is limited.

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 are not assured.

RECOMMENDED OPERATING CONDITIONS
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.
