Analog Devices / Maxim Integrated MAX15090B & MAX15090C Hot-Swap ICs

Analog Devices MAX15090B and 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 MAX15090B and MAX15090C integrate a hot-swap controller, 6mΩ power MOSFET, and electronic circuit-breaker protection in a single package. Each of these devices integrates an accurate current-sense circuitry and provides 220µA/A of proportional output current. The MAX15090B and MAX15090C are designed for the protection of 2.7V to 18.0V 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 (SOA) conditions. After the startup cycle is complete, on-chip comparators provide VariableSpeed and 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. Analog Devices MAX15090B and MAX15090C Hot-Swap ICs are available in a 28-bump Wafer-Level Package (WLP) and are rated over the -40°C to +85°C temperature range.
