Low side soft shutdown is initiated locally in an event over current, which is sensed by the DSL pin. It is
followed by the synchronized soft shutdown of the rest of the low side outputs; meanwhile it will hold all input
information for a period of tss until the soft shutdown finishes. Then the hard shutdown will be initiated to
complete the shut down cycle. (Figure 6.1)
High side soft shutdown is initiated locally in an event over current, which is sensed by the DSH pin. It is
followed by the synchronized soft shutdown of all the low side outputs; meanwhile it will hold all input information
for a period of tss until the soft shutdown finishes. Then the hard shutdown will be initiated to complete the shut
down cycle. (Figure 6.2)
Soft shutdown is initiated in an event of overcurrent, which is followed by turn-off all six outputs. The fault
condition will remain in a fixed period(tfault) even though the faultclear condition is in effect (Fig11). In the case
that faultclear is not in effect, fault duration = tfault + tfltclr.
