APPLICATIONS INFORMATION
The peak power at the fault current limit occurs at the supply
overvoltage threshold. The fault current limited power is:

Circuit Breaker with Foldback Current Limit
Figure 17 shows the LTC4253A in a foldback current limit
application. When V
OUT
 is shorted to the 48V RTN supply,
current flows through resistors R3 and R4. This results in
a voltage drop across R4 and a corresponding reduction
in voltage drop across the sense resistor, R
S
, as the ACL
amplifier servos the sense voltage between the SENSE and
V
EE
 pins to about 60mV . The short-circuit current through
RS reduces as the V
OUT
 voltage increases during an output
short-circuit condition. Without foldback current limiting
resistor R4, the current is limited to 3A during analog
current limit. With R4, the short-circuit current is limited
to 0.5A when V
OUT
 is shorted to 71V .
