R3118x Series  
0.6V detect VD with Delay Function and SENSE pin  
The R3118x Series are CMOS-based voltage detector ICs with the built-in output delay circuit that can operate at low voltage. Since  
R3118x has a SENSE pin for monitoring voltage separately from the power pin, its reset signal does not become unstable as long as  
power supply is secured and the "L" can be maintained. The detector threshold can be specified from 0.6V. The delay time can be set  
with an external capacitor connected to CD pin. In addition to SOT-23-5 and SC-88A packages, a 1.2mm square DFN(PLP)1212-6  
package is also available.  
FEATURES  
• Supply Current (ISS) ························Typ. 0.4μA (at release, VDD=6V)  
• Operating Voltage Range (VDD) ······1.0V to 6.0V  
• Reset Signal ···································"L"  
• Detector Threshold Accuracy ·········± 1.5% (-VDET 1.6V)  
>
=
• Detector Threshold Range (-VDET)··0.6V to 5.0V (internally fixed)  
• Temp. coeff. of Detector Threshold······Typ. ± 30ppm/°C  
• Output Delay···································Typ. 100ms delay set with a 0.022μF • Two Output Types···························Nch. Open Drain and CMOS  
external capacitor  
• Packages········································DFN(PLP)1212-6, SC-88A, SOT-23-5  
(The above shows specification at Topt=25 C. Design assurance value at -40 C Topt 85 C is also available. For details, please refer to the datasheet.)
