Product Summary

The LTC4218IGN#PBF is a Hot Swap Controller. The LTC4218IGN#PBF is a Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the gate of an external N-channel MOSFET for supply voltages from 2.9V to 26.5V. A dedicated 12V version (LTC4218IGN#PBF) contains preset 12V specific thresholds, while the standard LTC4218IGN#PBF allows adjustable thresholds. The LTC4218IGN#PBF provides an accurate (5%) current limit with current foldback limiting. The current limit threshold can be adjusted dynamically using an external pin. Additional features include a current monitor output that amplifies the sense voltage for ground referenced current sensing. Overvoltage, undervoltage and powergood monitoring are also provided. The applications of the LTC4218IGN#PBF include RAID Systems, ATCA, AMC, μTCA Systems, Server I/O Cards and Industrial.
