2 / 28 page VOLTAGE DETECTOR WITH OUTPUT DELAY RN5VD SERIES 1 OUTLINE The RN5VD Series are voltage detector ICs with output delay functions and high detector threshold accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low volt- age and is used,for instance, for system reset. Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an output driver, a hysteresis circuit and an output delay generator. The detector threshold is fixed with high accuracy in the IC and requires no adjustment. The RN5VD Series are operable by a lower voltage than that for the R ×5VL Series, and can be driven by a single battery. Two output types, Nch open drain type and CMOS type, are available. Since the package for these ICs are SOT-23-5(Mini-mold)package, high density mounting of the ICs on board is possible. • Output Delay ......................................................TYP. 100ms with external capacitor : 0.15µF • Ultra-low supply current...................................TYP. 1.0µA (RN5VD15 × : VDD=3.5V) • Broad Operating Voltage Range.......................0.7V to 10.0V • Detector Threshold ............................................Stepwise setting with a step of 0.1V in the range of 0.9V to 6.0V is ................................................................................possible.
