MAX5930, MAX5931 Low-Voltage, Triple, Hot-Swap Controllers/Power Sequencers/Voltage Trackers

The MAX5930 MAX5931 +1V to +13.2V triple hot-swap controllers provide complete protection for multisupply systems. They allow the safe insertion and removal of circuit cards into live Backplanes These devices hot swap multiple supplies ranging from +1V to +13.2V, provided one supply is at or above +2.7V and only one supply is above 11V. The input voltage rails (channels) CAN be configured to sequentially turn-on/off, track each other, or have completely independent operation.
The discharged Filter capacitors of the circuit card provide low impedance to the live Backplane High inrush currents from the Backplane to the circuit card CAN burn up connectors and components, or momentarily collapse the Backplane power supply leading to a system reset. The MAX5930 MAX5931 hot-swap controllers prevent such problems by gradually ramping up the output voltage and regulating the current to a preset limit when the board is plugged in, allowing the system to stabilize safely. After the startup cycle is complete, on-chip Comparators provide VariableSpeed/BiLevel protection against short-circuit and overcurrent faults, and provide immunity against system noise and load transients.
The load is disconnected in the event of a fault condition. The MAX5930 MAX5931 fault-management mode is selectable, allowing latched fault or autoretry after a fault condition.
The MAX5930 MAX5931 offer a variety of options to reduce external component count and design time. All devices integrate an on-board Charge Pump to drive the Gates of low-cost, external N-Channel MOSFETs an adjustable startup Timer and an adjustable current limit. The devices offer integrated features like startup current regulation and current glitch protection to eliminate external Timing resistors and capacitors. The MAX5931L provides an open-drain, active-low status output for each channel, the MAX5931H provides an open-drain, active-high status output for each channel, and the MAX5930 status output polarity is selectable.
The MAX5930 is available in a 24-pin QSOP package, and the MAX5931 is available in a 20-pin QSOP package. All devices are specified over the extended -40C to +85C temperature range.
