DESCRIPTION

The MP5077 provides up to 7A 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 MP5077 can

avoid inrush current during circuit start up.

MP5077 also provides programmable soft start

time, output discharge functions, OCP and

thermal shutdown features.

The maximum 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 10mΩ.

The MP5077 is available in a tiny 12-pin

2mmx2mm QFN package.
