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.
