MAX5955/MAX5956

The MAX5955 and MAX5956 are +1V to +13.2V dual

hot-swap controllers with independent on/off control for

complete protection of dual-supply systems. They allow

the safe insertion and removal of circuit cards into live

backplanes. The MAX5955 and MAX5956 operate

down to 1V provided one of the inputs is above 2.7V.

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 MAX5955 and MAX5956 hot-swap controllers pre-

vent 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™ protection

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

MAX5955B and MAX5956B must be unlatched after a

fault, and the MAX5955A and MAX5956A automatically

restart after a fault.

The MAX5955 and MAX5956 integrate an on-board

charge pump to drive the gates of low-cost, external n-

channel MOSFETs. The devices offer integrated fea-

tures like startup current regulation and current glitch

protection to eliminate external timing resistors and

capacitors. These devices provide open-drain status

outputs, an adjustable startup timer, and adjustable

current limits. The MAX5955 provides output undervolt-

age/overvoltage protection for each channel, while the

MAX5956 provides undervoltage/overvoltage monitor-

ing for each channel.

The MAX5955 and MAX5956 are available in a space-

saving 16-pin QSOP package.
