Adjusting the Fault Reporting and Power
Supply Latch-Off Delay Times
Figure 5 illustrates the relationship between the FLTN signal
and the gate drive outputs. Duration a, indicates the time
between FLTN starting to transition from High to Low,
(indicating a fault has occurred) and the start of the gate
drive outputs latching off. The latch-off is initiated by the
falling FLTN signal reaching the output latch threshold
voltage, VFLTN, TH. For additional details and wave forms
see HIP1011A Data Sheet FN4631. Table 1 illustrates the
effect of the FLTN capacitor on the response times.
