differ by more than 100mV, 100% of the load will come
from the higher of V1 or V2.
The user has the option of using E1 and E2 to disable
one of the two supplies by connecting them to a digital
controller. If E1 is brought low, V1 will no longer supply
current to V S . If E2 is brought high, V2 will no longer sup-
ply current to V S . If E1 is brought low and E2 is brought
high, V S will be disabled.
Figure 5 shows the same application without the shut-
down option. It has one-half the losses of Figure 4 and is
configured for 5V rails.

disabled. This rapid turn-off feature is desirable when the
supply cannot tolerate certain voltage excursions under
load, or when the load is being protected from a rapidly
changing input supply.
Under and Overvoltage Shutdown
Refer to Figure 6 for an application circuit which disables
the power to the load when the input voltage gets too low
or too high. When V IN starts from zero volts, the load to
the output is disabled until V IN reaches 5.5V. The V1 path is
enabled and the load remains on the input until the supply
exceeds 13.5V. At that voltage, the V2 path is disabled. As
the input falls, the voltage source will be reconnected to
the load when the input drops to 12V and the V2 path is
enabled. Finally, the load will be removed from the input
supply when the voltage drops below 5V.

The LTC4416-1 will support all three of the LTC4416
applications without the “soft-off” feature. The only dif-
ference in the two designs is the LTC4416-1 will rapidly
switch off the load from a supply whenever a channel is
