LTC4251-2 - Negative Voltage Hot Swap Controller

The LTC®4251/LTC4251-1/LTC4251-2 negative voltage Hot Swap™ controllers allow 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 pe.
