DESCRIPTION
The MP5048 is a monolithic, integrated
controller and switch. It contains a high-side
MOSFET and circuitry that enable it to operate
as a standalone device, or to be controlled by a
hot-swap controller. The MP5048 is capable of
driving up to 15A of continuous current per
MP5048 device.
The device limits the inrush current to the load
when a circuit card is inserted into a live
backplane power source. This limits the
backplane’s voltage drop. The MP5048 also
limits the internal MOSFET current by controlling
the gate voltage through the current-limit
reference input.
The MP5048 offers many features to simplify the
system design. It provides an integrated solution
to monitor the output current and the die
temperature, eliminating the need for an external
current-sense power resistor, power MOSFET,
or thermal sense.
The MP5048 detects the power FET gate,
source, and drain short conditions, and provides
feedback for the controller. The device can be
paralleled for higher current applications.
The MP5048 is available in an QFN-30
(5mmx5mm) package.
