ICs are integrated solution for hot-swap applications for safe insertion and removal of circuit line cards

Available from Mouser, Maxim MAX15090B/MAX15090C Hot Swap ICs are integrated solutions for hot-swap applications requiring the safe insertion and removal of circuit line cards from a live backplane. The devices integrate a hot-swap controller, 6mohm power MOSFET, and an electronic circuit-breaker protection in a single package. Each of these devices integrates an accurate current-sense circuitry and provide 220µA/A of proportional output current. The devices are designed for the protection of 2.7V to 18V supply voltages. These devices implement a foldback current limit during startup to control inrush current lowering di/dt and keep the MOSFET operating under safe operating area conditions. After the startup cycle is complete, on-chip comparators provide VariableSpeed/BiLevel protection against short-circuit and overcurrent faults, and immunity against system noise and load transients. The load is disconnected in the event of a fault condition. Suitable applications include for disk drive power, industrial, RAID systems, server I/O cards and storage bridge bay.
