♠ BQ25611D I2C Tswj 1-Cell 3.0-A Buck Battery Charger nrog USB Tshawb Pom thiab 1.2-A Boost Ua Haujlwm
Lub BQ25611D yog ib qho kev sib koom ua ke 3-A switchmode roj teeb them nqi tswj thiab lub zog tswj kev tswj cov cuab yeej rau tib lub xov tooj ntawm tes Li-Ion thiab Lipolymer roj teeb. Cov kev daws teeb meem yog sib xyaw nrog cov tswv yim thim rov qab-thaiv FET (RBFET, Q1), highside switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), thiab roj teeb FET (BATFET, Q4) ntawm lub kaw lus 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.
BQ25611D yog ib qho kev sib koom ua ke 3-A switchmode roj teeb them nqi 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 xov tooj ntse thiab cov ntsiav tshuaj. 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 tam sim no kev cai thiab roj teeb tej thaj chaw deb sensing xa lub siab tshaj plaws them hwj chim rau lub roj teeb.
