R3130 Series
Voltage Detector with Delay Function (Internal Counter Type)

Product Specifications

The R3130 Series are CMOS-based voltage detector ICs with the built-in output delay circuit. There is no hysteresis between the detector threshold and the released voltage. Reset signal is "L". A delay capacitor is not needed, because the output delay time is generated with the counter in the IC.

FEATURES

Operating Voltage Range (Maximum Rating) 1.0 V to 6.0 V (6.5 V)
Supply Current Typ. 1.25 µA (R313xN27xx: VDD=3.0V)
Detector Threshold Range 1.6 V to 4.8 V (0.1V steps)
Output Delay Time Typ. 50 ms or 240 ms
Detector Threshold Accuracy ±1.5%
Released Output Delay Time Accuracy ±10.0%
Detector Threshold Temperature Coefficient Typ. ±100 ppm/°C
Output Types Nch Open Drain and CMOS
Package SOT-23-3

TIMING CHART

The detector threshold is the same as the released voltage, not hysteresis.
