MP5991
16V, 50A, 1mΩ RDS(ON)
,
Hot-Swap Intelli-Fuse Solution
DESCRIPTION
FEATURES
The MP5991 is an integrated, monolithic
controller and switch with a power MOSFET
and other circuitry that allows it to work in
standalone operation or to be controlled via a
hot-swap controller. The device can drive up to
50A of continuous output current (IOUT) per
device at room temperature, and up to 60A of
continuous IOUT with air flow.

The device limits the backplane voltage drop by
limiting the inrush current to the load while a
circuit card is inserted into a live backplane
power source. It limits the internal MOSFET
current (IFET) by controlling the gate voltage
(VGATE) via the current limit (ILIMIT) reference
input and soft-start ramp.

The MP5991 provides many features to simplify
system design, such as an integrated current
mirror to monitor IOUT and the integrated on-die
temperature sense. This eliminates the need for
an external current-sense power resistor, power
MOSFET, and temperature-sense device.

Package
The IC detects the power MOSFET’s gate,
source, and drain short conditions. It also
provides feedback to the hot-swap controller via
the fault-reporting output (GOK). The MP5991
can operate in parallel for high-current
applications. During start-up, all of the devices
in parallel actively share current.
