MOSFET gate driver LT4200

IGBTinsulatedsilicon

Allows Safe Board Insertion into Live Backplane Wide Operating Voltage Range: 2.9V to 15V Guaranteed Safe Operating Area: 7.5W√s 1.2mΩ MOSFET with Current Sense Element ±4% Current Monitor Output Adjustable Current Limit Threshold Temperature Monitor Output Overtemperature Protection Adjustable Current Limit Timer Before Fault Power Good and Fault Outputs Adjustable Inrush Current Control ±2.5% Accurate Undervoltage and Overvoltage Protection Available in a 36-Pin (5mm × 8mm) QFN Package 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. High Availability Servers Solid State Drives
