Product Summary
The LTC4251CS6#TRPBF positive voltage Hot SwapTM controller allows a board to be safely inserted and removed from a live AMC or MicroTCA backplane. It controls the main 12V supply with an external N-channel MOSFET and the 3.3V auxiliary supply with an integrated switch. The 12V output ramp rate of LTC4251CS6#TRPBF is adjustable and includes inrush current limiting. The 12V output is also protected against short circuit faults with a fast acting current limit and a 5% accurate timed circuit breaker. The 3.3V output includes both soft start and overcurrent protection. The applications of the LTC4251CS6#TRPBF include Advanced Mezzanine Card, MicroTCA Systems, Workstations and Server I/O, Telecom Networks.
