Incazelo
I-TheLT®3650 iyishaja yebhethri ye-monolithic 2-cellLi-Ion/Polymer esebenza ngaphezu kuka-9V kuya ku-32V ububanzi bevolthi yokufaka (11.5V ubuncane be-voltage yokuqala).I-LT3650 ihlinzeka ngesici sokushaja samanje/i-voltage engaguquki, eneshaji ephezulu yamanje ehlelekayo ehlelekayo efika ku-2A, isethwe kusetshenziswa isivimbeli senzwa samanje sangaphandle.Isici sangaphambi kombandela sibiza kancane a
ibhethri le-voltage ephansi, nokutholwa kwebhethri elingalungile kunikeza isignali futhi kumise ukushaja uma ibhethri lingaphenduli esimweni sangaphambilini.
I-LT3650 ingalungiselelwa ukuthi inqamule ukushaja uma ishaji lamanje liwela ku-C/10, noma ingxenye eyodwa kweshumi ye-maximumcurrent ehleliwe.Uma sekuqediwe ukushaja, i-LT3650 ingena kumodi yokulinda yamanje ephansi (85µA).Isici sokuqalisa kabusha ngokuzenzakalela siqala umjikelezo omusha wokushaja uma amandla kagesi ebhethri ehla ngo-2.5% ukusuka ku-voltage ye-float, noma uma ibhethri elisha lifakwe ohlelweni lokushaja.
I-LT3650 iqukethe isibali-sikhathi sokuphepha sangaphakathi esihleleleka nomsebenzisi (ngokuvamile sisethelwa esikhathini somjikelezo ogcwele wamahora amathathu).I-IC ingalungiselelwa ukusebenzisa lesi sibali-sikhathi sangaphakathi uma kufunwa isikimu sokunqamula esisekelwe esikhathini lapho ukushaja kungaqhubeka ngaphansi kuka-C/10 kuze kufinyelelwe isikhathi esifiselekayo.
I-LT3650 itholakala ngephrofayili ephansi (0.75mm) 3mm × 3mm 12-pin DFN namaphakheji we-MSOP angu-12.
Uhlolojikelele
I-LT3650 iyishaja ephelele ye-monolithic, amandla aphakathi nendawo, i-Li-Ionbattery, ebhekana nezinhlelo zokusebenza zamandla kagesi okufakwayo aphezulu enezixazululo ezisebenzisa ubuncane bezingxenye zangaphandle.I-IC isebenzisa i-1MHz-frequency engaguquki, isilinganiso semodi yamanje yesakhiwo sokwehla.
I-LT3650 ihlanganisa ukushintsha kwe-2A eqhutshwa i-bootstrappedsupplytomaximizeefficiency phakathi nemijikelezo yokushaja.Ibanga lokufaka elibanzi livumela umsebenzi ukuthi ushaje ngokugcwele ukusuka ku-9V kuye ku-32V.Iphinikhodi yokuvala i-threshold enembayo ivumela ukufakwa komsebenzi we-UVLO kusetshenziswa isihlukanisi esilula esiphikisayo.I-IC ingaphinda ifakwe kumodi yokuvala shaqa yamanje ephansi, lapho ukuchema kokunikezwayo okokufaka kwehliswa kube ngu-15µA kuphela.
I-LT3650 ihlanganisa amazinga amaningana enkululeko yokulawula yamanje.Isamba esiphezulu sokushaja samanje sisethwa kusetshenziswa isivikeli senzwa samanje se-inductor.Iphinikhodi yohlelo yamanje yokushaja ivumela ukukhohliswa okuguquguqukayo kokushajwa kwebhethri yamanje.I-LT3650 iphinda ihlanganise isici sokulawula umkhawulo wokunikezwayo kokufaka kwesistimu esivumela ukushajwa kwebhethri kwamanje ukuze kuhlangatshezwane nezidingo zomthwalo wesistimu zizonke.
