allows a board to be safely inserted and removed from a  
livebackplane.Outputcurrentiscontrolledbythreestages

n
Programmable Timer with Drain Voltage  
Adjustable undervoltage and overvoltage detectors dis-  
connect the load whenever the input supply exceeds the  
desired operating range. The LTC4252’s supply input is  
shunt regulated, allowing safe operation with very high  
supply voltages. A multifunction timer delays initial start-  
up and controls the circuit breaker’s response time. The  
circuit breaker’s response time is accelerated by sensing  
excessive MOSFET drain voltage, keeping the MOSFET  
within its safe operating area (SOA). An adjustable soft-  
start circuit controls MOSFET inrush current at start-up.
