R3132 Series
Voltage Detector with Delay Function (Internal Counter Type)

Product Specifications

The R3132 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. By inputting "L" signal to MR pin, the manual reset signal is outputted. Reset signal is "L". A delay capacitor is not needed, because the output delay time of 240ms is generated with the counter in the IC.

FEATURES

Operating Voltage Range (Maximum Rating) 0.75 V to 6.0 V (6.5 V)
Supply Current Typ. 0.8 µA (R3132x27x: VDD=3.0V)
Detector Threshold Range 1.0 V to 5.0 V (0.1V steps)
Further, 2.32 V, 2.63 V, 2.93 V, 3.08 V, 4.38 V, and 4.63 V can be provided as standard.
Output Delay Time Typ. 240 ms
Reset Signal L
Detector Threshold Accuracy ±2.0%
Released Output Delay Time Accuracy ±15.0%
Detector Threshold Temperature Coefficient Typ. ±100 ppm/°C
Output Types Nch Open Drain and CMOS
Package SC-82AB, SON1612-6
