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.
