Product Overview

The LTC4251BCS6#TRMPBF is a negative voltage Hot Swap 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 feed forward path that limits peak current under worst-case catastrophic fault conditions. Programmable under voltage and over voltage detectors disconnect the load whenever the input supply exceeds the desired operating range. The 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 LTC4251B UV/OV thresholds are designed to match the standard telecom operating range of -43 to -75V.
  • Floating topology permits very high voltage operation
  • Programmable analog current limit with circuit breaker timer
  • Fast response time limits peak fault current
  • Improved ruggedness shunt regulator
  • Programmable timer
  • Programmable under-voltage/overvoltage protection
