The LT4200 is an integrated solution for hot swap applications that allows a board to be safely inserted and removed from a live backplane. The part integrates a hot swap controller, power MOSFET and current sense resistor into a single package for small form-factor applications. The MOSFET safe operating area is production tested and guaranteed for the stresses in hot swap applications. The LT4200 allows 50A of continuous operation at up to 85°C ambient temperature. It provides separate inrush current control and a ±12% accurate 57A current limit with output dependent foldback. The current limit threshold can be adjusted dynamically using the ISET pin. Additional features include a current monitor output for ground referenced current sensing and a MOSFET temperature monitor output. Thermal limit, overvoltage, undervoltage and power good monitoring are also provided.
