R3117xxx1/2 SERIES LOW VOLTAGE DETECTOR with SENSE pin NO.EA-186-200807 Notice If the SENSE pin voltage of R3117xxx1A/C and R3117Qxx2A/C make the gradual curve by raising 0.5V/ms or less, it may cause noise when the output voltage is switched from low to high. Please use R3117xxx3A/C and R3117Qxx4A/C Series for new designs instead of these products to avoid the above problem. 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 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.
