Circuit Breaker with Foldback Current Limit
Figure 17 shows the LTC4253A in a foldback current limit
application.WhenVOUTisshortedtothe–48VRTNsupply,
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, RS, as the ACL
amplifierservosthesensevoltagebetweentheSENSEand
VEE pins to about 60mV. The short-circuit current through
RS reduces as the VOUTvoltageincreasesduringanoutput
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 VOUT is shorted to 71V.
