LTC4218IGN#TRPBF

LTC4218 is a Hot Swap controller. It 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. This device 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 power good monitoring are also provided. It is widely used in application such as RAID systems, ATCA, AMC, µTCA systems, server I/O cards, industrial etc.
