R×5VL SERIES APPLICATION MANUAL
CONTENTS
R×5VL SERIES OUTLINE The R×5VL Series are voltage detector ICs with high detector threshold accuracy and ultra-low supply current by CMOS process. 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. Two output Types, Nch open drain type and CMOS type, are available. Three types of packages, TO-92, SOT-89 (Mini-power Mold), SOT-23-5 (Mini-mold), are available. 2.0V to 6.0V is possible (refer to Selection Guide).

R×5VL Output Delay Time tPLH is defined as follows: 1. In the case of Nch Open Drain Output: When the time at which a pulse voltage which increases from 1.2V to +VDET+2.0V is applied to VDD is Time A, and the time at which the output reaches 3.5V under the conditions that the output pin (OUT) is pulled up to 7V by a resistor of 100kΩis Time B, the time period from Time A through Time B. 2. In the case of CMOS Output: When the time at which a pulse voltage which increases from 1.2V to +VDET +2.0V is applied to VDD is Time A, and the time at which the output voltage reaches the voltage of (+VDET+2.0V)/2 is Time B, the time period from Time A through Time B.

R×5VL OPERATION FIG. 1 Block Diagram Operation Diagram Step 1. Output Voltage is equal to Power Source Voltage (VDD). Step 2. When Input Voltage to Comparator reaches the state of Vref ≥VDD·(Rb+Rc)/(Ra+Rb+Rc)at Point A (Detected Voltage –VDET), the output of Com- parator is reserved, so that Output Voltage becomes GND. Step 3. 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 reserved, so that Output Voltage becomes equal to Supply Voltage (VDD) FIG. 2 Operation Diagram Step Step 1 Step 2 Step 3 Step 4 Step 5 Comparator(+)Pin Input Voltage I II II II I Comparator Output H L Indefinite L H Tr. 1 OFF ON Indefinite ON OFF Output Tr.

R×5VL 1. When R×5VL××C (CMOS Output) is used in FIG. 8, this IC may oscillate by the through-type current at the detec- tion when impedance is connected between Power Source VDD and R×5VL VDD Pin.When R×5VL××A (Nch Open Drain Output) is used in FIG. 8, and R becomes excessively large, Detector Threshold may be varied because of the voltage drop of the supply current in the IC itself. 2. The connection as shown in FIG. 9 may cause the oscillation in both R×5VL××C (CMOS Output) and R×5VL××A (Nch Open Drain Output).

R×5VL TAPING SPECIFICATIONS (Unit: mm)
- TO-92 (Note) When taping is conducted, the pins of TO-92 are subjected to a particular forming. (Note) TZ type tape is not in the form of a reel, but is packed in a zigzag state in a box.Therefore, the tape can be used as either an RF type tape or an RR type tape,depending upon the pulling out direc- tion (B or F).
