PM2300 IS PART OF POWERHUB™ PRODUCT FAMILY
PowerHUB™isafamilyofproductsthatharnessawiderange
ofenergysourcestomakethechargingofthemobiledevices
easier.ThePowerHUB™familyprovidesanewlevelof
scalabilityinenergymanagementandchargingsolutionand
addressestheincreasingdemandforenergyinthenew
generationofhandhelddevices.PowerHUB™alsoleadsthe
trendtowardstheuseofnewenergysources.
Mostcurrenttabletsusehighcapacitysingle-cellLi-Ion
batteriesortwobatteriesinparallel,whichrequireseveral
hourstorecharge.ThePM2300,withitshighcharging
currentcapability,chargesbatteriesinhalfthetimeof
conventionalchargingcircuitry.
ThePM2300hasadualDC/DCstructurethatallowsthe
integrationofahighperformancepowerMOS.Thisleads
toimprovedefficiencyatlowercost.
ThePM2300alsobringsanoptimizedPCBfootprint
throughtheuseofsmallerandcheapercoilsthanthose
foundinexistingsolutions

PM2300 FLEXIBLE PROGRAMMABLE CHARGE PARAMETERS
ThebatteryCCCVchargingalgorithmiseitherfullyautono-
mouswhenoperatinginstandaloneorcontrolledbythehost
bysoftware.Awidesetofchargingparameterscanbemodi-
fiedormonitoredbyI²Candthroughinterruptpin.
Severalpre-defineddefaultsettingsareavailablefordifferent
applications.ThePM2300permanentlymonitorsseveralkey
parameterstooptimizechargingsuchaschargingvoltage,
chargingcurrent,batterytemperature,inputcurrent,voltage
anddietemperature.
