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 VrefVDD *(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) 14 R x5VL TEST CIRCUITS Rn:R x5VL xxA:100k ISS VDD VDD VDD Rx5VL SERIES Rx5VL SERIES OUT R x5VL xxC:None Rn VDD OUT VDET GND GND VSS VSS VSS FIG. 4 Detector Threshold Test Circuit FIG. 3 Supply Current Test Circuit VDD VDD VDD VDD Rx5VL SERIES OUT IOUT Rx5VLxxC OUT SERIES +VDS IOUT VDD -VDS GND GND VSS VSS VSS VSS FIG. 6 Pch Driver Output Current Test Circuit FIG. 5 Nch Driver Output Current Test Circuit +7.0V VDD +VDET+2.0V Rx5VLxxA OUT SERIES P.G. 1.2V VSS GND ROUT 100k OUT COUT VSS FIG. 7 Output Delay Time Test Circuit In Output Delay Time Test Circuit in FIG.7, it's Output Voltage Fall Times (tPHL) and Rise Times (tPLH) are defined as shown below. +VDET+2.0V +VDET+2.0V Input Voltage (VDD) Input Voltage (VDD) 1.2V 1.2V GND GND 7.0V +VDET+2.0V Output Voltage Output Voltage 3.5V +VDET+2.0V 2 GND GND tPHL tPLH Nch Open Drain Output tPHL tPLH CMOS Output 15 R x5VL TYPICAL CHARACTERISTICS 1) Supply Current vs. Input Voltage R x5VL27C R x5VL36C 3.0 4.0 25C 2.0 -30C 1.5 1.0 0.5 Supply Current Iss( A) Supply Current Iss(A) Topt=80C 2.5 0.0 Topt=80C 3.0 25C 2.0 -30C 1.0 0.0 0 1 2 3 4 5 6 7 8 Input Voltage VIN(V) 0 9 10 1 2 3 4 5 6 7 8 Input Voltage VIN(V) 9 10 R x5VL45C 3.0 Supply Current Iss(A) Topt=80C 2.5 25C 2.0 -30C 1.5 1.0 0.5 0.0 0 1 2 3 4 5 6 7 8 Input Voltage VIN(V) 9 10 2) Detector Threshold vs. Temperature R x5VL36C R x5VL27C 4.0 2.9 +VDET 2.8 2.7 2.6 2.5 -40 -20 16 -VDET 0 20 40 60 80 100 Temperature Topt(C) Detector Threshold VDET(V) Detector Threshold VDET(V) 3.0 3.9 3.8 +VDET 3.7 3.6 3.5 -40 -20 -VDET 0 20 40 60 80 100 Temperature Topt(C) R x5VL R x5VL45C Detector Threshold VDET(V) 4.9 +VDET 4.8 4.7 4.6 -VDET 4.5 4.4 -40 -20 0 20 40 60 80 100 Temperature Topt(C) 3) Output Voltage vs. Input Voltage R x5VL27A 3 2 1 0 0 1 2 3 Input Voltage VIN(V) 5 4 Topt=25C 4 3 2 1 0 0 1 2 3 4 Input Voltage VIN(V) 5 Topt=25C 6 Output Voltage VOUT(V) R x5VL36A Topt=25C Output Voltage VOUT(V) Output Voltage VOUT(V) 4 5 4 3 2 1 0 0 1 2 3 4 5 Input Voltage VIN(V) 6 17 R x5VL 4) Nch Driver Output Current vs. VDS R x5VL27C R x5VL36C Topt=25C 10 16 8 6 2.0V 4 1.5V 2 12 0.5 1.0 1.5 2.0 VDS(V) R x5VL45C 2.5 8 6 2.0V 4 0 0.0 3.0 2.5V 10 2 0 0.0 Topt=25C VIN=3.0V 14 Output Current IOUT(mA) Output Current IOUT(mA) VIN=2.5V 1.5V 0.5 1.0 1.5 2.0 2.5 3.0 3.5 VDS(V) Topt=25C 30 Output Current IOUT(mA) VIN=4.0V 25 3.5V 20 3.0V 15 10 2.5V 2.0V 1.5V 5 0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 VDS(V) 5) Nch Driver Output Current vs. Input Voltage R x5VL27C 10 R x5VL36C VDS=0.5V VDS=0.5V 14 8 Output Current IOUT(mA) Output Current IOUT(mA) Topt=-30C Topt=-30C 25C 6 4 80C 2 0 10 25C 8 6 80C 4 2 0 0 18 12 1 2 Input Voltage VIN(V) 3 0 1 2 3 Input Voltage VIN(V) 4 R x5VL R x5VL45C 8 VDS=0.5V Output Current IOUT(mA) Topt=-30C 25C 6 80C 4 2 0 0 1 2 3 4 Input Voltage VIN(V) 5 6) Pch Driver Output Current vs. Input Voltage R x5VL27C 3.5 VDS =2.1V 2.5 1.5V 2.0 1.5 1.0V 1.0 0.5V 0.5 0 Topt=25C 3.0 VDS=2.1V 2.5 1.5V 2.0 1.0V 1.5 1.0 0.5V 0.5 0.0 1 2 3 4 5 6 Input Voltage VIN(V) R x5VL45C 3.0 Output Current IOUT(mA) R x5VL36C Topt=25C Output Current IOUT(mA) Output Current IOUT(mA) 3.0 7 0 1 2 3 4 5 Input Voltage VIN(V) 6 7 Topt=25C VDS=2.1V 2.5 1.5V 2.0 1.5 1.0V 1.0 0.5V 0.5 0.0 0 1 2 3 4 5 Input Voltage VIN(V) 6 7 19 R x5VL 7) Output Delay Time vs. Load Capacitance 10 R x5VL27A Topt=25C Topt=25C 10 tPHL 1 tPHL 0.1 tPLH 0.01 0.0001 0.001 0.01 Load Capacitance COUT(F) R x5VL45A Output Delay Time tP(ms) 100 Topt=25C 10 1 tPHL tPLH 0.1 0.01 0.0001 20 0.1 0.001 0.01 Load Capacitance COUT(F) 0.1 Output Delay Time tP(ms) Output Delay Time tP(ms) tPLH 1 tPHL 0.1 tPLH 0.01 0.0001 0.001 0.01 Load Capacitance COUT(F) 0.1 R x5VL TYPICAL APPLICATION * R x5VL xxA CPU Reset Circuit (Nch Open Drain Output) (1) Input Voltage to R x5VL xxA is the same as (2) Input Voltage to R x5VL xxA is different the input voltage to CPU. from the input voltage to CPU.

When R x5VL xxC (CMOS Output) is used in FIG. 8, this IC may oscillate by the through-type current at the detection when impedance is connected between Power Source VDD and R x5VL VDD Pin.When R x5VL xxA (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.
