DESCRIPTION

The

MP5507E

is

an

integrated

power

management IC that provides a power backup

function for solid-state drive and hard-disk drive

applications.

The

MP5507E

provides

an

efficient and compact system solution with an

integrated, programmable, input-current limit

switch, energy storage, and a backup function.

The MP5507E applies

MPS’ patented energy

storage and release management technology to

minimize the required storage components,

system solution size, and cost. The MP5507E

boosts up the input voltage to a higher storage

voltage in normal condition and releases the

energy to the system when an input outage

occurs. The internal input current limit block

with DVDT control prevents inrush current

during system start-up and provides reverse

current blocking during the backup period. The

system voltage start-up slew rate can be

programmable.

The

storage

voltage

and

release voltage are both programmable for

different system applications.

The MP5507E requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-16

(2.5mmx3.2mm) package.
