Kev piav qhia
TheLT® 3650 yog ib qho ua tiav 2-cellLi-Ion / Polymer roj teeb charger uas ua haujlwm tshaj 9V txog 32V input voltage ntau yam (11.5V yam tsawg kawg nkaus pib-up voltage).LT3650 muab tus yam ntxwv tsis tu ncua-tam sim no / tsis tu ncua-voltage tus yam ntxwv, nrog cov nqi siab tshaj plaws tam sim no sab nraud programmable mus txog 2A, teeb tsa siv lub ntsuas hluav taws xob sab nraud.Ib tug precondition feature trickle-them a
roj teeb uas tsis muaj hluav taws xob, thiab kev tshawb pom lub roj teeb tsis zoo muab lub teeb liab thiab ncua kev them nyiaj yog tias lub roj teeb tsis teb rau qhov ua ntej.
LT3650 tuaj yeem teeb tsa los txiav tawm kev them nyiaj thaum them tam sim no poob rau C / 10, lossis ib feem kaum ntawm qhov programmed siab tshaj plaws tam sim no.Ib zaug them nyiaj, lub LT3650 nkag mus rau qhov qis tam sim no (85µA) standby hom.Ib qho kev pib rov pib dua pib pib lub voj voog tshiab yog tias lub roj teeb hluav taws xob poob 2.5% los ntawm qhov hluav taws xob ntab, lossis yog tias lub roj teeb tshiab tau muab tso rau hauv lub tshuab them nyiaj.
LT3650 muaj cov neeg siv-programmable nyob rau hauv kev nyab xeeb timer (feem ntau teem rau peb teev tag nrho lub sij hawm voj voog).Lub IC tuaj yeem teeb tsa los siv lub sijhawm sab hauv no yog tias xav tau lub sijhawm txiav tawm raws li qhov xav tau uas them tuaj yeem txuas ntxiv hauv qab C / 10 mus txog rau lub sijhawm xav tau.
Lub LT3650 muaj nyob rau hauv qhov qis profile (0.75mm) 3mm × 3mm 12-pin DFN thiab 12-pin MSOP pob.
Txheej txheem cej luam
LT3650 yog ib qho ua tiav monolithic, nruab nrab-lub zog, Li-Ionbattery charger, hais txog kev siv hluav taws xob ntau nrog cov kev daws teeb meem uas siv yam tsawg kawg ntawm cov khoom siv sab nraud.Lub IC siv 1MHz tas li-zaum, qhov nruab nrab tam sim no hom step-down architecture.
LT3650 suav nrog 2A hloov pauv uas tau tsav los ntawm bootstrappedsupplytomaximizeefficiency duringcharging cycles.Cov tswv yim dav dav tso cai rau kev ua haujlwm kom puv ntawm 9V txog 32V.Qhov kev txiav txim siab kaw tus pin tso cai rau kev koom ua ke ntawm UVLO kev ua haujlwm uas siv cov khoom sib cais yooj yim.Lub IC kuj tseem tuaj yeem muab tso rau hauv hom kaw tam sim no qis, uas cov khoom siv tawm tswv yim txo qis rau 15µA nkaus xwb.
LT3650 suav nrog ntau qib ntawm kev tswj hwm kev ywj pheej tam sim no.Tag nrho cov nqi siab tshaj plaws tam sim no tau teeb tsa siv lub zog sab nraud inductor tam sim no kev nkag siab resistor.Tus nqi siab tshaj plaws tam sim no programming tus pin tso cai rau dynamic manipulation ntawm lub roj teeb nqi tam sim no.Lub LT3650 kuj tseem suav nrog cov txheej txheem kev tawm tswv yim muab kev txwv tam sim no tswj kev ua haujlwm uas servos lub roj teeb them tam sim no kom haum rau tag nrho cov kev xav tau ntawm lub cev.
