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 soft-

start time, output discharge functions, over-

current 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, space-

saving QFN-12 (2mmx2mm) package.
