VOLTAGE DETECTOR WITH OUTPUT DELAY RN5VD SERIES APPLICATION MANUAL NO.EA-027-0006 VOLTAGE DETECTOR WITH OUTPUT DELAY RN5VD SERIES OUTLINE The RN5VD Series are voltage detector ICs with output delay functions and 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, a hysteresis circuit and an output delay generator. The detector threshold is fixed with high accuracy in the IC and requires no adjustment. The RN5VD Series are operable by a lower voltage than that for the R x 5VL Series, and can be driven by a single battery. Two output types, Nch open drain type and CMOS type, are available. Since the package for these ICs are SOT-23-5(Mini-mold)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 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) . 16 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" state. 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) 17 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 RN5VD xx C (CMOS Output) is used in FIG.10,this IC may oscillate by the through-type current at the detection when impedance is connected between Power Source VDD and RN5VD VDD Pin.When RN5VD xx A (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.
