be selected such the voltage V X should reach the threshold voltage (V IT,TH+ ) of the ITRIP functionality by the time that
the maximum allowable temperature is reached. The voltage of the ITRIP pin should not be allowed to exceed 5 V.
When using both the over-current protection and over-temperature protection with the ITRIP input, OR-ing diodes
(e.g., DL4148) can be used. This network is shown in Figure 16; the OR-ing diodes have been labeled D 1 and D 2 .

Truth Table: Undervoltage lockout, ITRIP, GF, PCFtrip and ENABLE
Table 4 provides the truth table for the IRS26302DJ. The first line shows that the UVLO for V CC has been tripped; the
FAULT output has gone low and the gate drive outputs have been disabled. V CCUV is not latched in this case and
when V CC is greater than V CCUV , the FAULT output returns to the high impedance state.
The second case shows that the UVLO for V BS has been tripped and that the high-side gate drive outputs have been
disabled. After V BS exceeds the V BSUV threshold, HO will stay low until the HVIC input receives a new rising 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. Same behavior if GF or PCFtrip threshold has been reached. 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.
