R3130 Series

Voltage Detector with Delay Function (Internal Counter Type)

  • Consumer
  • RoHS

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.
