n Allows Safe Board Insertion and Removal from a Live – 48V Backplane n Floating Topology Permits Very High Voltage Operation n Current Limit With Circuit Breaker Timer n Fast Response Time Limits Peak Fault Current n Programmable Soft-Start Current Limit n Programmable Timer with Drain Voltage Accelerated Response n ±1% Undervoltage/Overvoltage Threshold (LTC4252C) n Improved Ruggedness Shunt Regulator ■ Adjustable Undervoltage/Overvoltage Protection ■ LTC4252B-1/LTC4252C-1: Latch Off After Fault ■ LTC4252B-2/LTC4252C-2: Automatic Retry After Fault ■ Available in 8-Pin and 10-Pin MSOP Packages APPLICATIONS n Hot Board Insertion n Electronic Circuit Breaker n – 48V Distributed Power Systems n Negative Power Supply Control n Central Office Switching n High Availability Servers n ATCA The LTC®4252 negative voltage Hot SwapTM controller allows a board to be safely inserted and removed from a live backplane.
Output current is controlled by three stages of current limiting: a timed circuit breaker, active current limiting and a fast feedforward path that limits peak current under worst-case catastrophic fault conditions.
Adjustable undervoltage and overvoltage detectors disconnect the load whenever the input supply exceeds the desired operating range.
