♠ BQ25611D I2C Yoyendetsedwa ndi 1-Cell 3.0-A Buck Battery Charger yokhala ndi Kuzindikira kwa USB ndi 1.2-A Boost Operation
BQ25611D ndi chida chophatikizika kwambiri cha 3-A switchmode chowongolera batire ndi kasamalidwe kamagetsi kanjira kachipangizo ka cell single Li-Ion ndi Lipolymer.Yankho lake limaphatikizidwa kwambiri ndi ma input reverse-blocking FET (RBFET, Q1), highside switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), ndi batire FET (BATFET, Q4) pakati pa system ndi batire.Njira yochepetsera mphamvu yamagetsi imathandizira magwiridwe antchito a switch-mode, imachepetsa nthawi yolipiritsa batire ndikuwonjezera nthawi yothamanga ya batri panthawi yotulutsa.
BQ25611D ndi yophatikizika kwambiri ya 3-A switchmode kasamalidwe ka batire ndi kachitidwe ka Power Path kasamalidwe ka mabatire a Li-ion ndi Li-polymer.Imakhala ndi kulipiritsa mwachangu ndi chithandizo chamagetsi okwera pamapulogalamu osiyanasiyana kuphatikiza mafoni anzeru ndi mapiritsi.Njira yake yochepetsera mphamvu yamagetsi imathandizira magwiridwe antchito a switch-mode, imachepetsa nthawi yolipiritsa batire, ndikuwonjezera nthawi yothamanga ya batri panthawi yotulutsa.Magetsi ake olowetsa ndi malamulo omwe alipo komanso zowonera kutali za batri zimapereka mphamvu yothamangitsa batire.
• Kuchita bwino kwambiri, 1.5-MHz, chojambulira chosinthika cha switchmode buck
- Kuwongolera kwa 92% pa 2-A kuchokera ku 5-V kulowetsa
- ± 0.4% voteji malamulo ndi sitepe 10-mV
- Mapulogalamu osinthika a JEITA
- Kuzindikira kwa batri lakutali kuti kulipirire mwachangu
• Imathandizira USB On-The-Go (OTG) yokhala ndi zotulutsa zosinthika kuchokera ku 4.6 V mpaka 5.15 V
- Limbikitsani chosinthira chofikira mpaka 1.2-A
- 92% imakulitsa magwiridwe antchito pakutulutsa kwa 1-A
- Malire olondola apano (CC).
- Yambani mofewa mpaka 500-µF capacitive katundu
• Kulowetsa kamodzi kothandizira kulowetsa kwa USB, adapter yamagetsi apamwamba, kapena mphamvu zopanda zingwe
- Imathandizira 4-V mpaka 13.5-V voliyumu yowonjezera yokhala ndi 22-V mtheradi wolowetsa max
- 130-ns kuzimitsa mwachangu pachitetezo chamagetsi
- Programmable input current limit (IINDPM) ndi I
2C (100-mA mpaka 3.2-A, 100-mA/sitepe)
- Gawo la VINDPM mpaka 5.4-V limatsata basi mphamvu ya batri kuti ikhale yamphamvu kwambiri
- Dziwani zokha za USB SDP, CDP, DCP ndi ma adapter osakhazikika
• Kuwongolera njira zamagetsi za VDC (NVDC).
-Kuyatsa pompopompo popanda batire kapena batire lotulutsidwa kwambiri
• Low RDSON 19.5-mΩ BATFET kuti muchepetse kutayika kwa ma charger ndi kuwonjezera nthawi yoyendetsa batire
- Kuwongolera kwa BATFET pamasitima apamadzi, ndikukhazikitsanso dongosolo lonse popanda adaputala
• 7-µBatire yocheperako ikutha mumayendedwe apamadzi
• 9.5-µBatire yotsika yotayikira yomwe ili ndi makina oyimilira
• Mkulu wolondola batire kulipiritsa mbiri
- ± 6% kulipira malamulo apano
- ± 7.5% yolowera pano
- ± 3% VINDPM voltage regulation
- Nthawi yokhazikika yosinthira mabatire athunthu
• Kuphatikizika kwakukulu kumaphatikizapo ma MOSFET onse, kuzindikira kwamakono ndi malipiro a loop
• Zitsimikizo Zokhudzana ndi Chitetezo: - Chitsimikizo cha IEC 62368-1 CB
• Foni yam'manja, piritsi
• Zamagetsi zamafakitale, zamankhwala, zonyamula
