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. 5VT Series are operable by a lower voltage than that for the R × 5VL Series, and can be driven by a sinThe R × gle battery. Two output types, Nch open drain type and CMOS type, are available. Three types of packages, TO-92, SOT89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available.

In the case of CMOS Output, Output Voltage becomes unstable when Supply Voltage (VDD) is smaller than Minimum Operating Voltage. In the case of Nch Open Drain Output, a pulled-up voltage is output. Step 4. Output Voltage becomes equal to GND. Step 5. When Input Voltage to Comparator reaches the state of Vref≤VDD· (Rb)/(Ra+ Rb) at Point B (Released Voltage +VDET), the output of Comparator is reversed, so that Output Voltage becomes equal to Supply Voltage (VDD). 14 R× 5VT TEST CIRCUITS ISS VDD VDD R×5VT SERIES GND VSS VSS OUT VDD VDD Rn Rn:R×5VT××A:470kΩ R×5VT××C:None VDET R×5VT OUT SERIES GND VSS FIG. 3 Supply Current Test Circuit VDD VDD R×5VT SERIES OUT IOUT +VDS FIG. 4 Detector Threshold Test Circuit VDD VDD R×5VT××C OUT SERIES GND VSS VSS VSS IOUT VDD –VDS GND VSS FIG. 5 Nch Driver Output Current Test Circuit +5.0V +VDET+2.0V 0.7V VSS P.G.
