RN5VD SERIES LOW VOLTAGE DETECTOR WITH OUTPUT DELAY NO. EA-027-111103 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 VrefVDD * (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 VrefVDD * 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 (=0.69x 106x 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 x 10 6x CD (s) 15 RN5VD TEST CIRCUITS ISS +5V or VDD VDD VDD 470k 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 RN5VDxxC 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 470k 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 470k OUT GND 100% Output Voltage 50% Fig. 9 Output Delay Time Test Circuit GND tPHL *) at Fig.4,7,9.

When RN5VDxxC (CMOS Output) is used in Fig.10,this IC may oscillate by cross conduction current at the detection when impedance is connected between Power Source VDD and RN5VD VDD Pin.When RN5VDxxA (Nch Open Drain Output) is used in Fig.10, 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. 11 may cause the oscillation in both RN5VDxxC (CMOS Output) and RN5VDxxA (Nch Open Drain Output) 25 1.
