Low-Voltage, Triple, Hot-Swap Controllers/Power Sequencers/Voltage Trackers
General DescriptionThe 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 pro-
vide 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 volt-
age 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 com-
parators 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 condi-
tion. 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 cur-
rent 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 pack-
age. All devices are specified over the extended -40°C
to +85°C temperature range.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:All devices are 100% tested at TA= +25°C. Limits over temperature are guaranteed by design.
Note 3:The slow-comparator threshold is adjustable. VSC,TH= RLIMx 7.5µA + 25mV (see theTypical Operating Characteristics).
Note 4:The current-limit slow-comparator response time is weighed against the amount of overcurrent, the higher the overcurrent
condition, the faster the response time (see the Typical Operating Characteristics).
Note 5:The startup period (tSTART) is the time during which the slow comparator is ignored and the device acts as a current-limiter
by regulating the sense current with the fast comparator (see the Startup Periodsection).
Note 6:The current available at GATE is a function of VGATE(see the Typical Operating Characteristics).
Note 7:After a fault triggered by the fast comparator, the gate is discharged by the strong discharge current.
Note 8:Each channel input while the other inputs are at +1V.
Note 9:Each channel input while any other input is at +3.3V.
