DESCRIPTION

The MPQ5072 is a programmable load switch

that provides 1A of load protection across a 0.5V

to 5.5V voltage range. With low RDS(ON) in a tiny

package, the MPQ5072 provides a highly

efficient, space-saving solution for notebooks,

tablets, and other portable device applications.

The MPQ5072’s soft start (SS) function avoids

inrush current during circuit start-up. The

MPQ5072 also provides a programmable softstart

time, output discharge functions, overcurrent

protection (OCP), and thermal shutdown.

The maximum load at the output source is

current-limited, which 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 (GND).

An internal charge pump drives the power device

gate, allowing a low on resistance DMOS power

FET of 50mΩ.

The MPQ5072 is available in a tiny, spacesaving

QFN-12 (2mmx2mm) package.
