DESCRIPTION

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.

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.

The

MP5991

is

available

in

an

LGA-32

(5mmx5mm) package.
