DESCRIPTION

The MP5087A is a load switch, designed to

provide 7A load protection covering 0.5V to

package,

MP5087A

provides

very

high

efficiency

and

space-saving

solution

for

notebook, tablet and other portable applications.

With the soft start function, the MP5087A can

avoid inrush current during circuit start up. The

MP5087A also provides other features, like

power good, output discharge function, OCP

and thermal shutdown.

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 ILIM pin to ground.

This device comes in a tiny 2x2mm QFN12

package.

FEATURES

• Adjustable Start Up Slew Rate

• <1μA Shutdown Current

• Programmable 7A Current Limit Range

• Output Discharge Function

• Enable Pin

• <200ns Short-Circuitry Response Protection

• Thermal Protection

• Small QFN-12 (2mmx2mm) Package

APPLICATIONS

• Notebook and Tablet Computers

• Portable Devices

• Solid State Drivers

• Handheld Devices
