MAX15096 2.7V to 18V, 6A Integrated Hot-Swap/Electronic Circuit Breaker General Description Benefits and Features The MAX15096 family of devices are integrated solu- Integration Reduces Solution size for Blade Servers tions for hot-swap applications requiring the safe and Other Space-Constrained Designs insertion and removal of circuit line cards from a live Integrated 12m (typ) Internal Power MOSFET backplane. They can also be used as electronics Programmable Overvoltage Protection and circuit breaker for hard drive and solid-state drive and Undervoltage-Lockout Threshold fans. The devices integrate a hot-swap controller, 12m Drive-Present Signal Input (PRSNT pin) (typ) power MOSFET, and an electronic circuit-breaker Thermal Protection protection in a single package. Flexibility Enables Use in Many Unique Designs The devices are designed for protection of 2.7V to 18V 2.7V to 18V Operating Voltage Range supply voltages. These devices implement a foldback Programmable Inrush Current Control Under SOA Operation current limit during startup to control inrush current, lowering di/dt and keeping the MOSFET operating Adjustable Circuit-Breaker Current/Current-Limit Threshold under safe operating area (SOA) conditions. After the startup cycle is complete, on-chip comparators provide Programmable Slew-Rate Control Variable-Speed Circuit-Breaker Response VariableSpeed/BiLevel protection against short-circuit Latchoff (MAX15096) or Automatic Retry and overcurrent faults, and immunity against system (MAX15096A) Options noise and load transients. The load is disconnected in the event of a fault condition. The devices are factory Safety Features Ensure Accurate, Robust Protection calibrated to deliver accurate overcurrent protection with 6A (max) Load Current Capability 10% accuracy. During a fault condition, PG goes low 10% Circuit-Breaker Threshold Accuracy and the devices latch off (MAX15096) or automatic retry IN-to-OUT Short-Circuit Detection (MAX15096A) the output could also be discharged after Open-Drain PG Output a fault event (MAX15096D). Output Discharge After a Fault Event (MAX15096D Only) Programmable Additional Delay (2s max) to The devices feature an IN-to-OUT short-circuit detection Fast-Comparator Response Time before startup. The devices provide a power-MOSFET Enable Input (EN) GATE pin to program the slew rate during startup by adding an external capacitor. The devices have an under- Applications voltage/overvoltage input pin (UVOV) that can detect an Blade Servers undervoltage/overvoltage fault and disconnect the IN from Server I/O Cards the OUT. Additional features include internal overtem- RAID Systems perature protection and a power-good output (PG). Disk Drive Power The devices are available in a 16-bump, 2mm x 2mm Storage Applications wafer-level package (WLP) and are rated over the -40C Industrial Applications to +105C extended temperature range.
