♠ BQ25611D I2C Tswj 1-Cell 3.0-A Buck Battery Charger nrog USB Tshawb Pom thiab 1.2-A Boost Ua Haujlwm
BQ25611D yog ib qho kev sib koom ua ke 3-A switchmode roj teeb them nqi kev tswj hwm thiab lub zog txoj 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 FET (RBFET, Q1), highside switching FET (HSFET, Q2), qis sab hloov 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 cov roj teeb them lub sij hawm thiab ncua roj teeb khiav lub sij hawm thaum lub sij hawm tso 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 qis impedance zog optimizes hloov-hom kev ua hauj lwm efficiency, txo cov roj teeb lub sij hawm, thiab ncua roj teeb khiav lub sij hawm thaum lub sij hawm tso tawm theem.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.
