NCP302 and NCP303 series are measured with a 10 pF capacitive load. NCP303 has an additional 470 k pullup resistor
connected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low ‘L’ devices. Output
time delay t D1 and t D2 are dependent upon the delay capacitance. Refer to Figures 30, 31, and 32. The upper detector
threshold, V DET+ is the sum of the lower detector threshold, V DET ? plus the input hysteresis, V HYS .
