LTC4416/LTC4416-1
OPERATIO
V1 is Greater Than V2 Operation
When V E1 is below the V REF threshold, channel 1 is in
a “soft-off mode”. This means that G1 will only provide
an I G(SRC) current instead of an I G(SNK) or an I GFON(SNK)
current.
When V E1 is above the V REF threshold, channel 1 is im-
mediately fully enabled, and G1 will become active imple-
menting the output current listed in Figure 1.
Channel 2 is fully enabled. If V V1 – V VS < V RTO , channel 2
will implement all of the I G2 currents listed in Figure 1.
Channel 1 is Disabled
The LTC4416 is not designed to have channel 1 disabled
by grounding E1 and leaving E2 in an indeterminate state.
If this happens, the channel 2 PowerPath controller will
not have reverse turn-off capability. No electrical harm to
the LTC4416 will occur.
Both Channels Disabled
When both channels of the LTC4416 are disabled, both
G1 and G2 currents are set to I G(SRC) .
LTC4416-1 OPERATION
The LTC4416-1 is designed for overvoltage/undervoltage
protection or when either voltage path must be turned off
rapidly, regardless of the status of the other voltage input.
The LTC4416-1 does not implement the soft-off feature
implemented in the LTC4416. The E1 and E2 inactive will
force the I G current of their respective channel to I G(OFF) .
Table 2 explains the operation of the E1 and E2 inputs.
The term “active” implies that I G(OFF) current is forced on
the Gn pins regardless of the V Vn – V VS value. The term
“enabled” implies that I G(OFF) current is provide on the Gn
pins if and only if V Vn – V VS < V RTO .
Table.2 LTC4416-1 Operational Modes
Channel 2 is Disabled
The LTC4416 is not designed to have channel 2 disabled
by connecting E2 high and leaving E1 in an indeterminate
state. If this happens, the channel 1 PowerPath controller
will not have reverse turn-off capability. No electrical harm
to the LTC4416 will occur.

APPLICATIO S I FOR ATIO
LTC4416
The LTC4416 is designed to support three major ap-
plications. The first two applications assume that V1 is
the primary power source and V2 is the backup power
source. The first application is where the V1 power supply
is normally less than V2. The second application is where
the V1 power supply is normally greater than V2. The third
application addresses the load sharing case where both
V1 and V2 are relatively equal in value.
V1 is Less Than V2
Figure 2 illustrates the external resistor configuration for
this case.
