RN5VD SERIES LOW VOLTAGE DETECTOR WITH OUTPUT DELAY NO. EA-027-160309 OUTLINE The RN5VD 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, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high accuracy internally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available. Since the package for these ICs is SOT-23-5 package, high density mounting of the ICs on board is possible.

When input voltage (VDD) reaches the state of Vref≥VDD · (Rb+Rc) / (Ra+Rb+Rc) at point A (Detected Voltage –VDET) , the output of comparator is reversed, so that output voltage becomes GND. Discharging is performed from CD pin connected to an external capacitor. No delay time is generated. Step 3. Output voltage becomes indefinite when power source voltage(VDD) is smaller than minimum operating voltage. When the output is pulled up, VDD is output. Step 4. Output voltage becomes equal to GND. Step 5. When input voltage (VDD) reaches the state of Vref≤VDD · Rb/ (Ra+Rb) at Point B (Released Voltage +VDET) , the output of comparator is reversed, and the external capacitor is charged through CD pin, so that output voltage becomes equal to pulled-up voltage after a delay time tD (=0.69× 106× CD) . 14 RN5VD • Output Delay Operation Supply Voltage (VDD) CD pin Voltage Released Voltage (+VDET) CD pin Threshold Voltage (VTCD) GND Output Voltage (OUT) GND Output Delay Time (tD) When the supply voltage crosses the released voltage (+VDET) from a low value to a value higher than the released voltage (+VDET) , the CD pin voltage starts to increase (starts to charge the external capacitor). The output voltage is maintained at “L” level until the CD pin voltage reaches to VTCD (CD pin threshold voltage) after that the output voltage is reversed to “H”. The time period from beginning of charging capacitor to output voltage reversing represents the output delay (tD) . • Output Delay Time Delay time (tD) can be set accordance with the capacitance CD of external capacitor as below tD=0.69 × 10 6× CD (s) 15 RN5VD TEST CIRCUITS ISS +5V or VDD VDD VDD 470kΩ VIN VIN RN5VD SERIES RN5VD SERIES GND GND Fig. 3 Supply Current test Circuit Fig. 4 Detector Threshold Test Circuit VDD VDD VIN IOUT VIN RN5VD SERIES OUT OUT RN5VD××C SERIES VDS GND IOUT OUT VDD+VDS GND Fig. 5 Nch Driver Output Current Test Circuit Fig. 6 Pch Driver Output Current Test Circuit +5V or VDD VDD VDD VIN CD RN5VD SERIES VDS VIN 470kΩ ICD OUT CD OUT VDS GND GND Fig. 7 CD pin Threshold Voltage Test Circuit Fig. 8 CD pin Sink Current Test Circuit +VDET+2.0V +5V VDD Input Voltage CD VIN 0.7V CD GND RN5VD SERIES 470kΩ OUT GND 100% Output Voltage 50% Fig. 9 Output Delay Time Test Circuit GND tPHL *) at Fig.4,7,9.

And, the cross conduction current*1, which occurs when changing from the detecting state to the release state, is decreased the input voltage by [Cross Conduction Current] x [Resistance Value] only. And then, this device will enter the re-detecting state if the input voltage reduction is larger than the difference between the detector voltage and the released voltage. When the input resistance value is large and the VDD is gone up at mildly in the vicinity of the released voltage, repeating the above operation may result in the occurrence of output. As shown in Figure A/B, set R1 to become 100 kΩ or less as a guide, and connect CIN of 0.1 μF and more to between the input pin and GND. Besides, make evaluations including temperature properties under the actual usage condition, with using the evaluation board like this way. As a result, make sure that the cross conduction current has no problem.
