MAX5931BEEP+T General Description

The MAX5930A/MAX5931A/MAX5931B +1V to +15Vtriple hot-swap controllers provide complete protectionfor multisupply systems. They allow the safe insertionand removal of circuit cards into live backplanes. Thesedevices hot swap multiple supplies ranging from +1V to+15V, provided one supply is at or above +2.7V. Theinput voltage rails (channels) can be configured tosequentially turn-on/off, track each other, or have com-pletely independent operation.The discharged filter capacitors of the circuit card providelow impedance to the live backplane. High inrush cur-rents from the backplane to the circuit card can burn upconnectors and components, or momentarily collapse thebackplane power supply leading to a system reset. TheMAX5930A/MAX5931A/MAX5931B hot-swap controllersprevent such problems by gradually ramping up the out-put voltage and regulating the current to a preset limitwhen the board is plugged in, allowing the system to sta-bilize safely. After the startup cycle is complete, on-chipcomparators provide VariableSpeed/BiLevel™ protectionagainst short-circuit and overcurrent faults, and provideimmunity against system noise and load transients.The load is disconnected in the event of a fault condi-tion. The MAX5930A/MAX5931A/MAX5931B fault-man-agement mode is selectable, allowing latched fault orautoretry after a fault condition.The MAX5930A/MAX5931A/MAX5931B offer a variety ofoptions to reduce external component count anddesign time. All devices integrate an on-board chargepump to drive the gates of low-cost, external n-channelMOSFETs, an adjustable startup timer, and anadjustable current limit. The devices offer integratedfeatures like startup current regulation and currentglitch protection to eliminate external timing resistorsand capacitors. The MAX5931A provides an open-drain, active-low status output for each channel, theMAX5931B provides an open-drain, active-high statusoutput for each channel, and the MAX5930A status out-put polarity is selectable.The MAX5930A is available in a 24-pin QSOP package,and the MAX5931A/MAX5931B are available in a 20-pinQSOP package. All devices are specified over theextended -40°C to +85°C temperature range.
