The MAX5904–MAX5909 dual hot-swap controllersprovide complete protection for dual-supply systems.These devices hot swap two supplies ranging from +1Vto +13.2V, provided one supply is at or above 2.7V,allowing the safe insertion and removal of circuit cardsinto live backplanes.The discharged filter capacitors of the circuit card pro-vide low impedance to the live backplane. High inrushcurrents from the backplane to the circuit card can burnup connectors and components, or momentarily col-lapse the backplane power supply leading to a systemreset. The MAX5904 family of hot-swap controllers pre-vents such problems by gradually ramping up the outputvoltage and regulating the current to a preset limit whenthe board is plugged in, allowing the system to stabilizesafely. After the startup cycle is completed, two on-chipcomparators provide VariableSpeed/BiLevel™ protec-tion against short-circuit and overcurrent faults, as wellas immunity against system noise and load transients. Inthe event of a fault condition, the load is disconnected.The MAX5905/MAX5907/MAX5909 must be unlatchedafter a fault, and the MAX5904/MAX5906/MAX5908 auto-matically restart after a fault.The MAX5904 family offers a variety of options to reducecomponent count and design time. All devices integratean on-board charge pump to drive the gates of low-cost,external n-channel MOSFETs. The devices offer integrat-ed features like startup current regulation and currentglitch protection to eliminate external timing resistors andcapacitors. The MAX5906–MAX5909 provide an open-drain status output, an adjustable startup timer, anadjustable current limit, an uncommitted comparator,and output undervoltage/overvoltage monitoring.The MAX5904/MAX5905 are available in 8-pin SO pack-ages. The MAX5906–MAX5909 are available in space-saving 16-pin QSOP packages.
