5 LOW VOLTAGE DETECTOR R 5VT LINE The R 5VT Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low voltage 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 and a hysteresis circuit. The detector threshold is fixed with high accuracy. The R 5VT 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.

When R 5VT C (CMOS Output) is used in FIG. 9, this IC may oscillate by the through-type current at the detection when impedance is connected between Power Source and R 5VT Pin.When R 5VT A (Nch Open Drain Output) is used in FIG. 9, and R becomes excessively large, may be varied because of the voltage drop of the supply current in the IC itself. 2. The connection as shown in FIG. 1 may cause the oscillation in both R 5VT C (CMOS Output) and R 5VT A (Nch Open Drain Output). 24
