NCP300 and NCP301 series are measured with a 10 pF capacitive load. NCP301 has an additional 470 k pull−up resistor con-
nected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low ‘L’ devices. The upper
detector threshold, VDET+ is the sum of the lower detector threshold, VDET− plus the input hysteresis, VHYS.
