Datasheet Summary
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 parator, 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,...
