TIMING RELATIONSHIPS
Figure 1 illustrates some of the power on sequences,
including the UV and OV differentials to their reference,
and Power Good cascading.
Figure 1. Complete Power On Timing Sequence
Figures 2, 3, and 4 indicate the affect on the VGATE
signal caused by different Circuit Breaker inputs. In
Figure 2 RESET# and MODE
are high; in Figure 3
MODE is low. Figure 4 shows the Quick Trip mode.
