Cov txiaj ntsig khoom
- thermal tswj thiab tiv thaiv overvoltage
Kev tswj cov cua kub yog lwm qhov kev sib tw loj rau cov neeg tsim qauv roj teeb charger.Txhua lub charger nti ntsib qhov kev poob qis thaum lub sij hawm them nqi vim yog cua sov dissipation.Txhawm rau kom tsis txhob muaj roj teeb puas lossis kaw lub kaw lus, feem ntau cov chargers suav nrog qee hom kev tswj hwm los tswj cov cua sov tsim.Cov cuab yeej siv tshiab siv cov tswv yim tawm tswv yim ntau dua los saib xyuas qhov kub thiab txias thiab kho tus nqi tam sim no dynamically lossis los ntawm kev suav ntawm tus nqi proportional rau qhov hloov pauv ntawm qhov kub thiab txias.Qhov kev txawj ntse built-in no tso cai rau lub charger nti tam sim no maj mam txo cov nqi them tam sim no kom txog thaum lub thermal sib npaug mus txog thiab qhov kub ntawm qhov tuag tsis nce.Lub tshuab no tso cai rau lub charger txuas ntxiv them lub roj teeb ntawm qhov siab tshaj plaws tam sim no yam tsis ua rau lub kaw lus kaw, yog li txo lub sijhawm them roj teeb.Feem ntau cov khoom siv tshiab niaj hnub no tseem yuav feem ntau ntxiv cov txheej txheem tiv thaiv overvoltage.
Lub charger BQ25616JRTWR muab ntau yam kev nyab xeeb rau cov roj teeb them thiab cov haujlwm ua haujlwm, suav nrog roj teeb tsis zoo kub coefficient thermistor saib xyuas, them nyiaj kev nyab xeeb timer thiab overvoltage thiab tiv thaiv dhau tam sim no.Thermal regulation txo cov nqi tam sim no thaum qhov sib txuas kub tshaj 110 ° C.Cov zis STAT qhia txog cov xwm txheej them thiab txhua yam kev ua txhaum.
Daim ntawv thov Scenario
Lub roj teeb charger nti belongs rau ib hom kev tswj fais fab, daim ntawv thov ntau yam dav heev.Txoj kev loj hlob ntawm lub hwj chim tswj chips yog ib qho tseem ceeb rau kev txhim kho kev ua tau zoo ntawm tag nrho lub tshuab, kev xaiv ntawm lub hwj chim tswj chips yog ncaj qha cuam tshuam rau cov kev xav tau ntawm lub system, thaum lub sij hawm txoj kev loj hlob ntawm lub hwj chim tswj chips tseem yuav tsum tau hla tus nqi barrier.
BQ25616/616J yog ib qho kev sib koom ua ke 3-A hloov-hom roj teeb tswj kev tswj hwm thiab lub zog txoj kev tswj cov cuab yeej rau tib lub xov tooj ntawm tes Li-Ion thiab Li-polymer roj teeb.Cov kev daws teeb meem yog kev sib koom ua ke nrog cov tswv yim thim rov qab-thaiv FET (RBFET, Q1), sab siab hloov FET (HSFET, Q2), qis sab hloov FET (LSFET, Q3), thiab roj teeb FET (BATFET, Q4) ntawm qhov system thiab roj teeb.Txoj kev uas tsis muaj zog impedance optimizes switch-hom ua hauj lwm efficiency, txo lub sij hawm them roj teeb thiab ncua sij hawm roj teeb khiav lub sij hawm tawm theem.
BQ25616/616J yog ib qho kev sib koom ua ke 3-A hloov-hom roj teeb tswj thiab system Power Path tswj ntaus ntawv rau Li-ion thiab Li-polymer roj teeb.Nws nta them ceev ceev nrog kev txhawb nqa siab input voltage rau ntau yam kev siv nrog rau cov hais lus, kev lag luam, thiab cov khoom siv kho mob portable.Nws txoj kev tsis muaj zog impedance ua kom zoo dua qhov kev ua haujlwm ntawm kev hloov pauv, txo lub sijhawm them roj teeb, thiab txuas ntxiv roj teeb lub sijhawm thaum lub sijhawm tso tawm.Nws cov input voltage thiab kev cai tam sim no xa ntau lub zog them rau lub roj teeb.
Cov kev daws teeb meem yog kev sib koom ua ke nrog cov tswv yim thim rov qab-thaiv FET (RBFET, Q1), sab siab hloov FET (HSFET, Q2), qis sab hloov FET (LSFET, Q3), thiab roj teeb FET (BATFET, Q4) ntawm qhov system thiab roj teeb.Nws kuj tseem txuas nrog lub bootstrap diode rau lub rooj vag siab-sab tsav rau kev tsim qauv yooj yim.Cov kev teeb tsa kho vajtse thiab cov xwm txheej qhia muab kev teeb tsa yooj yim los teeb tsa cov kev daws teeb meem.
