TheLT®3650 ndeyemonolithic 2-cellLi-Ion/Polymer bhatiri charger inoshanda pamusoro pe9V kusvika 32V yekupinza voltage renji (11.5V shoma yekutanga-up voltage).Iyo LT3650 inopa inogara-ikozvino / inongogara-voltage yekuchaja hunhu, ine yakanyanya kuchaja iripo kunze inorongwa kusvika ku2A, yakaiswa uchishandisa yekunze ikozvino inopikisa.A precondition feature trickle-charges a
low voltage bhatiri, uye bhatiri rakashata rinoonekwa rinopa chiratidzo uye inomisa kuchaja kana bhatiri rikasadaira kune preconditioning.
Iyo LT3650 inogona kugadzirwa kuti imise kuchaja kana chaja iripo ichiwira kuC/10, kana chikamu chimwe chete mugumi chezvakarongwa zvakanyanya.Kana chaja chapera, iyoLT3650 inopinda yakaderera ikozvino (85µA) yekumira mode.Chinhu chekutanga-otomatiki chinotanga kutenderera kutsva kwekuchaja kana bhatiri voltage yadonha 2.5% kubva pamhepo inoyangarara, kana bhatiri idzva rakaiswa muchaji system.
Iyo LT3650 ine mushandisi-inorongwa yemukati yekuchengetedza timer (kazhinji yakaiswa kumaawa matatu akazara kutenderera nguva).Iyo IC inogona kugadziridzwa kuti ishandise iyi yemukati timer kana nguva-yakavakirwa yekumisa chirongwa ichidikanwa umo kuchaja kunogona kuenderera pasi peC/10 kusvika nguva yaunoda yasvika.
Iyo LT3650 inowanikwa mune yakaderera chimiro (0.75mm) 3mm × 3mm 12-pini DFN uye 12-pini MSOP mapakeji.
Overview
LT3650 ndeye yakazara monolithic, yepakati-simba, Li-Ionbattery charger, inogadzirisa yakakwira yekupinza voltage maapplication ane mhinduro dzinoshandisa hushoma hwekunze zvinhu.Iyo IC inoshandisa 1MHz inogara-frequency, avhareji yazvino modhi nhanho-pasi architecture.
Iyo LT3650 inosanganisira 2A switch iyo inofambiswa nebootstrappedsupplytomaximizeefficiency panguva yekuchaja ma cycles.Iyo yakafararira yekuisa siyana inobvumira oparesheni kuti izere kubva pa9V kusvika 32V.Pini chaiyo yekuvhara chikumbaridzo inobvumira kubatanidzwa kweUVLO mashandiro uchishandisa iri nyore resistor divider.Iyo IC inogona zvakare kuiswa mune yakaderera ikozvino yekudzima modhi, umo iyo yekuisa yekuisa bias inoderedzwa kusvika 15µA chete.
Iyo LT3650 inosanganisira akati wandei madhigirii ekuchaja ikozvino kudzora rusununguko.Iyo yakazara yekuchajisa yazvino inosetwa uchishandisa yekunze inductor current sense resistor.Iyo yakanyanya kuchaja ikozvino purogiramu yepini inobvumira kushandura kune simba kwebhatiri kuchaja ikozvino.Iyo LT3650 inosanganisirawo system yekuisa yekugovera ikozvino muganho wekudzora ficha iyo inosevha iyo bhatiri kuchaja ikozvino kuti ikwane yakazara system mutoro zvinodiwa.
