VOL TAGE 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 × 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.

Moreover, such values for any two items must not be reached simultaneously. Operation above these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only and do not necessarily imply functional operation below these limits. 5 R N5VD ELECTRICAL CHARACTERISTICS • RN5VD09A/C Topt=25˚C Symbol Item Conditions MIN. TYP. MAX.

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) . 16 R N5VD • Output Delay Operation Supply Voltage (VDD) Released Voltage (+VDET) CD pin Voltage 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 × 10 6× CD (s) 17 R N5VD TEST CIRCUITS ISS +5V or VDD VDD VIN RN5VD SERIES GND VIN RN5VD SERIES GND OUT VDD 470kΩ FIG. 3 Supply Current test Circuit FIG. 4 Detector Threshold Test Circuit VDD VIN RN5VD SERIES GND OUT VDS IOUT VDD VIN RN5VD××C SERIES GND IOUT OUT VDD+VDS FIG. 5 Nch Driver Output Current Test Circuit FIG. 6 Pch Driver Output Current Test Circuit +5V or VDD VDD VIN CD VDS RN5VD SERIES GND VDD 470kΩ OUT OUT VDS VIN ICD CD RN5VD SERIES GND FIG. 7 CD pin Threshold Voltage Test Circuit FIG. 8 CD pin Sink Current Test Circuit +VDET+2.0V +5V VDD 470kΩ OUT Input Voltage CD VIN 0.7V GND RN5VD SERIES GND CD 100% Output Voltage 50% FIG. 9 Output Delay Time Test Circuit GND tPHL tD *) at FIG.4,7,9.
