Chiyambi cha Zamalonda
Chip chojambulira batri ndi chip chomwe chingathe kulipira ndi kulamulira mabatire osiyanasiyana, kuchokera ku batri imodzi ya lithiamu, batri imodzi ya lithiamu iron phosphate, kapena mabatire awiri kapena anayi a NiMH.
Zizindikiro za Ntchito
Zofunikira zazikulu zama charger amakono ndi nthawi yolipirira yaifupi komanso chitetezo (palibe kuwonongeka kwa batri komanso moyo wofupikitsa wa batri).Izi zimafuna chojambulira chokhala ndi dera lophatikizika lomwe limatha kuyendetsa mafunde apamwamba komanso luso lozindikira mwamphamvu komanso kuyendetsa bwino.Nthawi zambiri, ma charger othamanga amakhala ndi nthawi yolipiritsa yosakwana ola limodzi motero amafunikira charging chambiri.
Za Zamalonda
BQ25896 ndi njira yophatikizika kwambiri ya 3-A switch-mode charger management and system power power management device for single cell Li-Ion and Li-polymer battery.Zipangizozi zimathandizira kuthamangitsa voteji mwachangu.Njira yochepetsera mphamvu yamagetsi imathandizira magwiridwe antchito a switch-mode, imachepetsa nthawi yolipiritsa batire ndikuwonjezera moyo wa batri panthawi yotulutsa.Mawonekedwe a I2C seri omwe ali ndi ma charger ndi makina amachitidwe amapangitsa chipangizocho kukhala chosinthika chosinthika.
Chipangizochi chimathandizira magwero osiyanasiyana olowera ndipo chimatenga zotsatira kuchokera kudera lodziwika mudongosolo, monga chipangizo cha USB PHY.Kusankha kwaposachedwa komanso kuwongolera mphamvu zamagetsi kumalumikizidwa ndi USB 2.0 ndi USB 3.0 mphamvu yamagetsi.Kuphatikiza apo, Input Current Optimizer (ICO) imathandizira kuzindikira kwamphamvu kwamphamvu kwa gwero lolowera popanda kulemetsa.Chipangizochi chimakumananso ndi mawonekedwe a mphamvu ya USB On-the-Go (OTG) popereka 5 V (Adjustable 4.5V-5.5V) pa VBUS ndi malire apano mpaka 2 A.
Kuwongolera njira zamagetsi kumawongolera kachitidweko pang'ono pamwamba pa voteji ya batri koma sikutsika pansi pa 3.5V yochepa mphamvu yamagetsi (yokonzekera).Ndi mbali iyi, dongosololi limagwira ntchito ngakhale batri ikatha kapena kuchotsedwa.Pamene malire apano kapena malire a voteji akafikira, kasamalidwe ka mphamvu kamene kamachepetsa mtengowo mpaka ziro.Pamene katundu wa dongosolo akupitirirabe kuwonjezeka, njira yamagetsi imatulutsa batri mpaka mphamvu yamagetsi ikwaniritsidwe.
Ntchito Yowonjezera iyi imalepheretsa kudzaza gwero lolowera.
Chipangizochi chimaperekanso chosinthira cha 7-bit analog-to-digital (ADC) chowunikira ma voltages apano ndi ma input/battery/system (VBUS, BAT, SYS, TS).Pini ya QON imapereka BATFET kuloleza / kukonzanso kuwongolera kuti mutuluke munjira yotsika yamphamvu yapamadzi kapena ntchito yokonzanso dongosolo lonse.
Banja la chipangizocho likupezeka mu 24-pin, 4 x 4 mm2 x 0.75 mm woonda WQFN phukusi.
Future Trends
Tsogolo likulonjeza tchipisi tamagetsi.Kupyolera mukupanga njira zatsopano, kulongedza, ndi njira zopangira dera, padzakhala zipangizo zogwira ntchito bwino kwambiri.Amatha kukonza kachulukidwe kamagetsi, kukulitsa moyo wa batri, kuchepetsa kusokoneza kwa ma elekitiroma, kukulitsa mphamvu ndi kukhulupirika kwa ma sign ndikusintha chitetezo chamakina, kuthandiza mainjiniya padziko lonse lapansi kuti akwaniritse zatsopano.
