DESCRIPTION

The MP5073 provides up to 2A load protection

over a 0.5V to 5.5V voltage range. With the

high efficiency and space saving solution for

notebooks, tablets, and other portable/battery-

operated applications.

With the soft start function, the MP5073 can

avoid inrush current during circuit start up.

MP5073 also provides programmable soft start

time, output discharge functions, OCP and

thermal shutdown features.

The max load at the output (source) is current

limited. This is accomplished by utilizing a

sense FET topology. The magnitude of the

current limit is controlled by an external resistor

from the ILIM pin to ground.

An internal charge pump drives the gate of the

power device, allowing a very low on-resistance

DMOS power FET of just 5

0mΩ.

The MP5073 is available in a tiny 12-pin 2mmx2mm

QFN

package.
