R3117x SERIES
LOW VOLTAGE DETECTOR with SENSE pin
NO.EA-186-080617
OUTLINE
The R3117x series are CMOS-based voltage detector ICs 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.
Each of these ICs consists of a voltage reference unit, a comparator, resistors for detector threshold setting,
an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy internally and does
not require any adjustment.
The tolerance of the detector threshold is ±15mV (-VDET <= 1.5V) or ±1.0% (1.5V< -VDET). Since the sense pin is
separated from the VDD pin of the IC, therefore, even if the sense pin voltage becomes to 0V, the output voltage
keeps its "L" level.
Two output types, Nch open drain type and CMOS type are available.
Three types of packages, SOT-23-5, SC-88A, and DFN(PLP)1010-4 are available.

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.
