The MAX15091/MAX15091A 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, 18mΩ (typ) power MOSFET, and an electronic circuit-breaker protection in a single package. The devices integrate an accurate current-sense circuitry and provide 170µA/A of proportional output current. The devices are designed for 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 (SOA) 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. The devices are factory calibrated to deliver accurate overcurrent protection with ±10% accuracy. During a fault condition, the MAX15091 latches off, while the MAX15091A enters autoretry mode. The devices feature an IN to OUT short-circuit detection before startup. The devices provide a power-MOSFET GATE pin to program the slew rate during startup by adding an external capacitor. The devices have overvoltage/undervoltage input pins that can detect an overvoltage/undervoltage fault and disconnect the IN from the OUT. Additional features include internal overtemperature protection, power-good output, and fault-indicator output. The MAX15091/MAX15091A are available in a 28-pin, 5mm × 5mm TQFN power package and are rated over the -40°C to +85°C extended temperature range.
