Truth Table: Undervoltage lockout and ITRIP
Table 2 provides the truth table for the IRS233(0,2)(D). The first line shows that the UVLO for V

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. The fault output stays in the
low state until the fault condition has been removed by all LINx set to high state. Once the fault is removed, the voltage on the
FAULT pin will return to V
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 and LIN. The working principle of the new filter is shown
in Figures 12 and 13.
Figure 12 shows a typical input filter and the asymmetry of the input and output. The upper pair of waveforms (Example 1)
