Truth Table: Undervoltage lockout, ITRIP, and ENABLE
Table 4 provides the truth table for the IRS2336xD. The first line shows that the UVLO for V

(IRS2336(D)) or rising (IRS23364D) transition of HIN. The third case shows the normal operation of the HVIC. The
fourth case illustrates that the ITRIP trip threshold has been reached and that the gate drive outputs have been
disabled and a fault has been reported through the fault pin. In the last case, the HVIC has received a command
through the EN input to shutdown; as a result, the gate drive outputs have been disabled.
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, and EN inputs. The working
principle of the new filter is shown in Figures 17 and 18.
Figure 17 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
difference between the input signal and t
duration slightly longer then t

Figure 18 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
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
