General Description
The MAX5904–MAX5909 dual hot-swap controllers
provide complete protection for dual-supply systems.
These devices hot swap two supplies ranging from +1V
to +13.2V, provided one supply is at or above 2.7V,
allowing the safe insertion and removal of circuit cards
into live backplanes.
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 col-
lapse the backplane power supply leading to a system
reset. The MAX5904 family of hot-swap controllers pre-
vents 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 completed, two on-chip
comparators provide VariableSpeed/BiLevel protec-
tion against short-circuit and overcurrent faults, as well
as immunity against system noise and load transients. In
the event of a fault condition, the load is disconnected.
The MAX5905/MAX5907/MAX5909 must be unlatched
after a fault, and the MAX5904/MAX5906/MAX5908 auto-
matically restart after a fault.
The MAX5904 family offers a variety of options to reduce
component count and design time. All devices integrate
an 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 current
glitch protection to eliminate external timing resistors and
capacitors. The MAX5906–MAX5909 provide an open-
drain status output, an adjustable startup timer, an
adjustable 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.
