Kufotokozera
TheLT®3650 ndi charger yathunthu ya monolithic 2-cellLi-Ion/Polymer yomwe imagwira ntchito mopitilira 9V mpaka 32V voliyumu yolowera (11.5V yochepa yoyambira).LT3650 imapereka mawonekedwe anthawi zonse / nthawi zonse-voltage charger, okhala ndi kuchuluka kwamphamvu komwe kumapangidwira mpaka 2A, kukhazikitsidwa pogwiritsa ntchito chopinga chakunja chakunja.A precondition feature trickle-charges a
batire yotsika kwambiri, komanso kuzindikira kwa batire yoyipa kumapereka chizindikiro ndikuyimitsa kuyitanitsa ngati batire silikuvomereza kukhazikitsidwa kale.
LT3650 ikhoza kukonzedwa kuti ithetse kuyitanitsa pomwe chiwongola dzanja chikugwera ku C/10, kapena gawo limodzi mwa magawo khumi laomwe adapangidwa.Ikangotha, theLT3650 imalowa mumayendedwe ocheperako (85µA).Choyambitsanso choyambitsanso chimayamba kuyitanitsa kwatsopano ngati mphamvu ya batri itsika ndi 2.5% kuchokera pamagetsi oyandama, kapena ngati batire yatsopano ikalowetsedwa mu charger.
LT3650 ili ndi chowerengera chachitetezo chamkati chotheka ndi ogwiritsa ntchito (nthawi zambiri chimakhala cha maola atatu athunthu).IC ikhoza kukhazikitsidwa kuti igwiritse ntchito nthawi yamkatiyi ngati ndondomeko yothetsa nthawi ikufunidwa momwe kulipiritsa kungapitirire pansi pa C / 10 mpaka nthawi yomwe mukufuna.
LT3650 imapezeka muzithunzi zochepa (0.75mm) 3mm × 3mm 12-pin DFN ndi 12-pin MSOP phukusi.
Mwachidule
LT3650ndi yathunthu monolithic, yapakati-mphamvu, Li-Ionbattery charger, poyankha ma voliyumu apamwamba olowera ndi mayankho omwe amagwiritsa ntchito zida zakunja zochepa.IC imagwiritsa ntchito 1MHz pafupipafupi, pafupifupi masitepe apakatikati.
LT3650 imaphatikizapo chosinthira cha 2A chomwe chimayendetsedwa ndi bootstrappedsupplytomaximizeefficiency pa nthawi yacharging.Kuyika kosiyanasiyana kumapangitsa kuti ntchitoyo ikhale yodzaza kuyambira 9V mpaka 32V.Pini yotsekera yolondola imalola kuphatikizika kwa magwiridwe antchito a UVLO pogwiritsa ntchito chogawaniza chosavuta.IC imathanso kuyikidwa munjira yotsika yotsekera, momwe kukondera kothandizira kumachepetsedwa kukhala 15µA yokha.
LT3650 imaphatikizanso magawo angapo a ufulu wowongolera pano.Chiwongoladzanja chokwanira chamakono chimayikidwa pogwiritsa ntchito mphamvu yakunja ya inductor panopa.Pini ya pulogalamu yamakono yolipiritsa kwambiri imalola kusintha kwamphamvu kwa batire lakali pano.LT3650 imaphatikizansopo gawo lothandizira pakuwongolera malire omwe amathandizira mabatire apano kuti akwaniritse zofunikira zonse zamakina.
