Kev piav qhia rau TPS781
TPS781 tsev neeg ntawm cov neeg poob qis (LDO) regulators muab cov txiaj ntsig ntawm ultralow zog (KuvQ= 1µA), ntim khoom me me (2 × 2 SON-6), thiab xaiv tau ob theem tso zis voltage.Ib qho kev hloov kho tau kuj muaj, tab sis tsis muaj peev xwm hloov cov qib voltage.
Tus VSETtus pin tso cai rau tus neeg siv kawg hloov ntawm ob theem voltage ntawm-tus-ya los ntawm microprocessor-tshaj tawm tswv yim.Qhov LDO no tau tsim tshwj xeeb rau cov ntawv siv roj teeb uas xav tau ob theem voltages.Nrog ultralow IQ(1µA), microprocessors, nco phaib, thiab cov pa luam yeeb yog cov ntawv thov zoo rau cov cuab yeej no.
Ultralow-power thiab selectable dual-theem tso zis voltages tso cai rau cov neeg tsim qauv los kho lub zog noj rau cov kev siv tshwj xeeb.Cov neeg tsim qauv tam sim no tuaj yeem hloov mus rau qib qis dua hauv cov qauv siv roj teeb thaum lub microprocessor nyob rau hauv kev pw tsaug zog, ntxiv kom txo tau tag nrho cov kev siv hluav taws xob.Ob theem voltage yog preset ntawm lub Hoobkas los ntawm ib tug tshwj xeeb architecture siv EPROM.Cov txheej txheem EPROM tso cai rau ntau qhov tso zis voltage xaiv ntawm VSETTsawg (1.5V rau 4.2V) thiab VSETsiab (2.0V rau 3.0V) nyob rau hauv cov zis tso zis version nkaus xwb.Saib cov lus hauv cov ntaub ntawv no lossis sab laj nrog koj tus neeg sawv cev ntawm lub Hoobkas hauv zos kom paub meej cov kev xaiv voltage thiab xaj cov ntaub ntawv;Yam tsawg kawg nkaus xaj yuav siv tau.
TPS781 series yog tsim los ua tau raws li TI MSP430 thiab lwm yam khoom zoo sib xws.Tus pin qhib tau sib xws nrog tus qauv CMOS logic.Qhov LDO no ruaj khov nrog cov zis capacitor ntau dua 1.0µF.Yog li ntawd, kev siv ntawm cov cuab yeej no yuav tsum muaj qhov tsawg kawg nkaus ntawm lub rooj tsavxwm vim tias cov ntim ntim me me thiab lub peev xwm me me tso zis capacitor.TPS781 series IQ(1µA) kuj tuaj nrog thermal kaw thiab tam sim no txwv los tiv thaiv cov cuab yeej thaum muaj teeb meem.Txhua pob khoom muaj qhov ntsuas kub ntawm TJ= -40 ° C rau + 125 ° C.Rau cov ntawv thov kev ua haujlwm siab uas xav tau kev xaiv dual-theem voltage, xav txog TPS780 series, nrog rau kuvQntawm 500nA thiab dynamic voltage scaling.
