EVALUATION KIT AVAILABLE MAX15090B/MAX15090C 2.7V to 18V, 12A, Hot-Swap Solution with Current Report Output General Description Benefits and Features The MAX15090B/MAX15090C 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 6m (typ) Internal Power MOSFET backplane. The devices integrate a hot-swap controller, Overvoltage Protection 6m 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 220A/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 or Automatic Retry Options against short-circuit and overcurrent faults, and immunity Safety Features Ensure Accurate, Robust Protection against system noise and load transients. The load is 12A (max) Load Current Capability disconnected in the event of a fault condition. The devices 10% Circuit-Breaker Threshold Accuracy are factory calibrated to deliver accurate overcurrent Inrush Current Regulated at Startup with Foldback protection with 10% accuracy. During a fault condition, Implementation for di/dt Control the MAX15090B latches off, while the MAX15090C enters IN-to-OUT Short-Circuit Detection autoretry mode. The devices feature an IN-to-OUT short-circuit detection Ordering Information and Recommended Application before startup. The devices provide a power-MOSFET Circuit for Hot-Swap Applications appear at end of GATE pin to program the slew rate during startup by data sheet. adding an external capacitor. The devices have overvolt- age/undervoltage input pins that can detect an overvolt- Typical Application Circuit age/undervoltage fault and disconnect the IN from the OUT. Additional features include internal overtemperature 12V protection, power-good output, and fault-indicator output. IN OUT The MAX15090B/MAX15090C ICs are available in a 6 x 10F TVS GATE 10 28-bump, 2.07mm x 3.53mm, power wafer-level package VCC 5600pF 12V 178k DC-DC (WLP) and are rated over the -40C to +85C extended REGULATOR 1F 3.3V OUTPUT MAX15090B temperature range.
