Maxim’s 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 house a hot-swap controller, 18 mΩ power MOSFET and electronic circuit-breaker protection in a single package.
The chips integrate accurate current-sense circuitry and provide 170 μA/A of proportional output current. They are designed for protection of 2,7 V to 18 V 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 over-current 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 over-current protection with ±10% accuracy. During a fault condition, the MAX15091 latches off, while the MAX15091A enters auto-retry mode.
The devices feature an IN to OUT short circuit detection before startup, and provide a power MOSFET GATE pin to program the slew rate during startup by adding an external capacitor. The devices have over-voltage/under-voltage input pins that can detect a fault and disconnect the IN from the OUT. Additional features include internal over-temperature protection, power-good output and fault indicator output.
The ICs are available in a 28-pin, 5 x 5 mm TQFN power package and are rated over the -40°C to
