  • Description

    The RP300 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. A delay capacitor is not needed, because the output delay time of 50 ms or 200 ms is generated with the counter in the IC. Additionally, the high accuracy output delay time at ±5% allows easy control of the start-up sequence. In addition to SOT-23-5 packages, a 1mm square DFN(PL)1010-4B package is also available.
