Figure 10. SD failure due to overcurrent
Figure 11. SD failure due to undervoltage (UVLO below 70 μs) shows the shutdown event as the result of an
undervoltage condition on the V
CC
supply. If V
CC
drops below the undervoltage threshold, the shutdown can stop
the application. If the voltage on V
CC
rises above the V
CC
on threshold in less than 70 μs, the SD event time is
about 70 μs.

Figure 12. SD failure due to undervoltage (UVLO above 70 μs) shows the shutdown event as the result of an
undervoltage condition on the V
CC
supply. In this case, the drop on V
CC
is greater than 70 μs. The SD event time
is the same as the duration of drop.
