Inkcazo
I-TheLT®3650 yitshaja yebhetri eyi-2-cellLi-Ion/Polymer egcwele monolithic esebenza ngaphaya kwe-9V ukuya kwi-32V yoluhlu lwamandla ombane (11.5V ubuncinane bombane wokuqalisa).I-LT3650 inika uphawu lwentlawulo eqhubekayo-yangoku / rhoqo-i-voltage, kunye nentlawulo ephezulu ngoku ngaphandle kweprogrammable ukuya kwi-2A, iseti usebenzisa i-resistor yangaphandle yangoku.A precondition feature i-trickle-charges a
ibhetri yombane ophantsi, kunye nokubhaqwa kwebhetri engalunganga kunika uphawu kwaye kumiswe ukutshaja ukuba ibhetri ayiphenduli kwimeko yangaphambili.
I-LT3650 inokuqwalasela ukuphelisa ukutshaja xa intlawulo yangoku iwela kwi-C/10, okanye isinye kwishumi le-programmed maximumcurrent.Xa itshaja iphelile, iLT3650 ingena kwimo yokulinda ephantsi yangoku (85µA).Isici sokuqalisa ngokutsha ngokuzenzekelayo siqala umjikelo omtsha wokutshaja ukuba amandla ombane ebhetri awehla nge-2.5% ukusuka kumbane odadayo, okanye ukuba ibhetri entsha ifakwe kwisixokelelwano sokutshaja.
I-LT3650 iqulethe i-timer-programmable yangaphakathi yokhuseleko lwangaphakathi (ngokuqhelekileyo imiselwe iiyure ezintathu zexesha elipheleleyo lomjikelo).I-IC inokuqwalaselwa ukuba isebenzise le timer yangaphakathi ukuba iskimu sokuphelisa esisekwe kwixesha sifunwa apho ukutshaja kungaqhubeka ngaphantsi kwe-C/10 de kufike ixesha elifunwayo.
I-LT3650 ifumaneka kwiprofayili ephantsi (0.75mm) 3mm × 3mm i-12-pin DFN kunye ne-12-pin MSOP iiphakheji.
Isishwankathelo
I-LT3650 yi-completemonolithic, i-mid-power, itshaja ye-Li-Ionbattery, ejongene nezicelo zombane ophezulu kunye nezisombululo ezisebenzisa ubuncinci bamacandelo angaphandle.I-IC isebenzisa i-1MHz rhoqo-i-frequency, i-avareji yemowudi yangoku ye-step-down architecture.
I-LT3650 idibanisa i-2A switch eqhutywa yi-bootstrappedsupplytomaximizeefficiencyduringcharging cycles.Uluhlu olubanzi lwegalelo luvumela umsebenzi ukuba utshaje ngokupheleleyo ukusuka kwi-9V ukuya kwi-32V.Iphini yokuvala umgubasi ochanekileyo ivumela ukubandakanywa komsebenzi we-UVLO usebenzisa isahluli esilula sokuchasa.I-IC inokuphinda ifakwe kwimowudi yokuvala ephantsi yangoku, apho igalelo lokubonelela ngegalelo lincitshiswe ukuya kwi-15µA kuphela.
I-LT3650 idibanisa amanqanaba amaninzi enkululeko yolawulo lwangoku.Ubuninzi bentlawulo yangoku lusetwa kusetyenziswa i-inductor yangoku yokumelana nengqiqo.Ubuninzi beqhosha lenkqubo langoku livumela ukuguqulwa kwebhetri yangoku.I-LT3650 ikwabandakanya igalelo lenkqubo yonikezelo lwenkqubo yolawulo lomda wolawulo olusebenzayo olusebenzisa intlawulo yebhetri yangoku ukulungiselela iimfuno zomthwalo wenkqubo iyonke.
