EVALUATION KIT AVAILABLE MAX15093/MAX15093A 2.7V to 18V, 15A, Hot-Swap Solution with Current Report Output General Description Benefits and Features The MAX15093/MAX15093A ICs are integrated Integration Reduces Solution Size for Blade Servers solutions for hot-swap applications requiring the safe and Other Space-Constrained Designs insertion and removal of circuit-line cards from a live Integrated 3.8m (typ) Internal Power MOSFET backplane. The devices integrate a hot-swap controller, Overvoltage Protection 3.8m power MOSFET, and an electronic circuit-breaker Power-Good and Fault Outputs Programmable Undervoltage Lockout protection in a single package. Current Reporting Without Need for External The devices integrate an accurate current-sense R SENSE circuitry and provide 160A/A of proportional output Thermal Protection current. The devices are designed for protection of 2.7V Flexibility Enables Use in Many Unique Designs to 18V supply voltages. 2.7V to 18V Operating Voltage Range These devices implement a foldback current limit during Adjustable Circuit-Breaker Current/Current-Limit startup to control inrush current lowering di/dt and keep Threshold the MOSFET operating under safe operating area (SOA) Programmable Slew-Rate Control conditions. After the startup cycle is complete, on-chip Variable-Speed Circuit-Breaker Response comparators provide VariableSpeed/BiLevel protection Latchoff (MAX15093) or Automatic Retry against short-circuit and overcurrent faults, and immunity (MAX15093A) Options against system noise and load transients. The load is Safety Features Ensure Accurate, Robust Protection disconnected in the event of a fault condition. The devices 15A Continuous Load Current Capability are factory calibrated to deliver accurate overcurrent 10% Circuit-Breaker Threshold Accuracy protection with 10% accuracy. During a fault condition, Inrush Current Regulated at Startup with Foldback the MAX15093 latches off, while the MAX15093A enters Implementation for di/dt Control autoretry mode. IN-to-OUT Short-Circuit Detection The devices feature an IN-to-OUT short-circuit detection before startup. The devices provide a power-MOSFET Ordering Information and Recommended Application GATE pin to program the slew rate during startup by adding Circuit for Hot-Swap Applications appear at end of an external capacitor. The devices have overvoltage/ data sheet. undervoltage input pins that can detect an overvoltage/ undervoltage fault and disconnect the IN from the OUT. Typical Application Circuit Additional features include internal overtemperature 12V protection, power-good output, and fault-indicator output. IN OUT 6 x 10F TVS The MAX15093/MAX15093A ICs are available in a 10 GATE 40-bump, 2.57mm x 4.03mm, power wafer-level package VCC 5600pF 12V 17.8k (WLP) and are rated over the -40C to +105C extended 1F MAX15093 temperature range.
