Advanced Input Filter
The advanced input filter allows an improvement in the input/output pulse symmetry of the HVIC and helps to reject
noise spikes and short pulses. This input filter has been applied to the HIN, LIN, PFCin and EN inputs. The working
principle of the new filter is shown in Figures 19 and 20.
Figure 19 shows a typical input filter and the asymmetry of the input and output. The upper pair of waveforms
(Example 1) show an input signal with a duration much longer then t FIL,IN ; the resulting output is approximately the
difference between the input signal and t FIL,IN . The lower pair of waveforms (Example 2) show an input signal with a
duration slightly longer then t FIL,IN ; the resulting output is approximately the difference between the input signal and
t FIL,IN .
Figure 20 shows the advanced input filter and the symmetry between the input and output. The upper pair of
waveforms (Example 1) show an input signal with a duration much longer then t FIL,IN ; the resulting output is
approximately the same duration as the input signal. The lower pair of waveforms (Example 2) show an input signal
with a duration slightly longer then t FIL,IN ; the resulting output is approximately the same duration as the input signal.

Short-Pulse / Noise Rejection
This device’s input filter provides protection against short-pulses (e.g., noise) on the input lines. If the duration of the
input signal is less than t FIL,IN , the output will not change states. Example 1 of Figure 21 shows the input and output in
the low state with positive noise spikes of durations less than t FIL,IN ; the output does not change states. Example 2 of
Figure 21 shows the input and output in the high state with negative noise spikes of durations less than t FIL,IN ; the
output does not change states.
