♠ 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 batire imodzi ya Li-Ion ndi Lipolymer. Yankho lake limaphatikizidwa kwambiri ndi FET (RBFET, Q1), ma switching FET (HSFET, Q2), FET (LSFET, Q3), ndi batri FET (BATFET, Q4) pakati pa makina 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 kachipangizo 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 yothamanga ya batri
- 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 yokhazikika pakuyitanitsa batire yonse
• 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
