Ingaruka
Uruhare rwa voltage yerekanwe.
Mubikorwa byateganijwe byerekanwe, ubunyangamugayo bwibikoresho bitanga isoko (gutandukana kwagaciro ka voltage, drift, igipimo cyoguhindura, nibindi bipimo byerekana) nibyiza cyane kurenza ibisanzwe bisanzwe bigenga diode cyangwa bitatu bya terefone, irakoreshwa rero mugukenera imbaraga-zuzuye za voltage nkumuvuduko wa voltage, muri rusange kuri A / D, D / A, hamwe nisoko ryumubyigano mwinshi, ariko kandi na sisitemu zimwe na zimwe zikurikirana amashanyarazi nazo zikoresha isoko ya voltage.
Ibyiciro
Itondekanya rya voltage yerekanwe.
Ukurikije imbere imbere, imiterere ya voltage itanga imiterere iratandukanye, voltage yerekanwe igabanijwemo imirongo ya voltage yerekana na voltage igenzura voltage ibyiciro bibiri.Imiterere ya bande ya voltage yerekanwe ni imbere-ibogamye ya PN ihuza hamwe na voltage ijyanye na VT (ubushobozi bwumuriro) murukurikirane, ukoresheje coeffisente yubushyuhe bubi bwa PN hamwe nubushyuhe bwiza bwubushyuhe bwa VT kugirango ugere ku ndishyi zubushyuhe.Imiterere ya voltage yerekana imiterere nuruhererekane rwo guhuza ibice byo munsi yo gusenyuka no guhuza PN, ukoresheje coefficente yubushyuhe bwiza bwumuteguro hamwe nubushuhe bubi bwubushyuhe bwa PN kugirango uhagarike indishyi zubushyuhe.Kumeneka munsi bifasha kugabanya urusaku.Umuvuduko wa voltage ya tube voltage yerekanwe ni hejuru (hafi 7V);ibyerekeranye na voltage ya bandgap voltage yerekanwa iri hasi, iyanyuma rero ikoreshwa cyane aho ingufu nke zitangwa.
Ukurikije imiterere yo hanze yububiko, voltage yerekanwe mubice bibiri: urukurikirane hamwe.Iyo ushyizwe mu bikorwa, urukurikirane rw'amashanyarazi rwerekana ibintu bisa na bitatu-bigengwa n'amashanyarazi, aho imbaraga za voltage zahujwe zikurikirana hamwe n'umutwaro;parallel voltage yerekanwe isa na voltage igenzura, aho voltage yerekana ihujwe nuburemere.Byombi bande ya voltage yerekanwe hamwe na tube voltage yerekanwa irashobora gukoreshwa muribi bice byombi.Ibyiza byuruhererekane rwa voltage yerekana ni uko basaba gusa ibyinjijwe kugirango batange umutuzo wa chip no gutanga imizigo iyo umutwaro uhari;parallel voltage yerekanwe isaba kubogama kubushakashatsi bwashyizweho kugirango burenze igiteranyo cya chip yo gutuza ya chip hamwe nuburemere ntarengwa bwo gutwara ibintu kandi ntibikwiye kubushobozi buke bwo gukoresha.Ibyiza bya parallel voltage yerekanwe ni uko bibogamye, birashobora guhuza intera nini yinjiza voltage, kandi birakwiriye gukoreshwa nkibikoresho byahagaritswe.
Guhitamo
Guhitamo urukurikirane rwa voltage yerekana chip hamwe na parike ya voltage yerekanwe
Urukurikirane rwa voltage rwerekana rufite ibintu bitatu: VIN, VOUT, na GND, bisa nkumurongo ugenzura, ariko hamwe nibisohoka biri hasi kandi byukuri.Urukurikirane rw'amashanyarazi rwerekanwe muburyo bukurikiranye n'umutwaro (Igishusho 1) kandi urashobora gukoreshwa nka rezistor igenzurwa na voltage iri hagati ya VIN na VOUT.Muguhindura imbere yimbere, itandukaniro riri hagati yagaciro ka VIN nigabanuka rya voltage hejuru yumurwanya wimbere (bingana na voltage yerekana kuri VOUT) igumaho.Nkuko ikigezweho ari nkenerwa kubyara ingufu za voltage, igikoresho gikeneye gushushanya umubare muto wumuvuduko wa ciescent kugirango wizere ko amabwiriza ya voltage nta mutwaro.Urukurikirane rwahujwe na voltage yerekanwe bifite ibiranga bikurikira.
- Umuvuduko w'amashanyarazi (VCC) ugomba kuba muremure bihagije kugirango umuyaga uhagije ugabanuke imbere yimbere, ariko umuyaga mwinshi cyane ushobora kwangiza igikoresho.
- Igikoresho hamwe nububiko bwacyo bigomba kuba bishobora gukwirakwiza imbaraga za seriveri igenzura.
- Nta mutwaro, imbaraga zonyine zo gukwirakwiza ni ituze ryumuvuduko wa voltage yerekanwe.
.
Iringaniza rya voltage yerekanwe ifite ama terinal abiri: HANZE na GND.Irasa na primaire na diode igenga voltage ariko ifite ibimenyetso byiza biranga voltage, bisa na diode ya voltage igenzura résistor yo hanze kandi ikora ibangikanye numutwaro (Ishusho 2).Iringaniza rya voltage rishobora gukoreshwa nkumubyigano ugenzurwa numuyoboro uhuza OUT na GND, muguhindura imiyoboro yimbere kugirango itandukaniro riri hagati yumuriro wogutanga nigabanuka rya voltage hejuru ya ristoriste R1 (bingana na voltage yerekanwa kuri OUT) igumaho gihamye.Shyira mu bundi buryo, parallel type voltage reference ikomeza voltage ihoraho kuri OUT ukomeza igiteranyo cyumutwaro wumuvuduko numuyoboro unyura mumashanyarazi ya voltage.Ubwoko bubangikanye bufite ibimenyetso bikurikira.
- Guhitamo R1 ibereye byemeza ko ingufu zisabwa zujujwe kandi parallel parallel voltage yerekana nta mbibi zifite kuri voltage ntarengwa.
- Umuyoboro ntarengwa utangwa nuwigenga ntushobora kwikorera umutwaro hamwe numuyoboro utangwa unyuze mumuzigo kandi ibyerekezo bikenera kubyara ingufu zikwiranye na ristoriste R1 kugirango ikomeze voltage ihoraho.

Iyo itandukaniro riri hagati yuruhererekane na parallel ya voltage yerekanwe bimaze gusobanuka, igikoresho gikwiye gishobora gutoranywa kubikorwa byihariye.Kugirango ubone igikoresho gikwiye, nibyiza gusuzuma byombi hamwe nibisobanuro bifatika.Iyo ibipimo byubwoko bwombi bimaze kubarwa byumwihariko, ubwoko bwibikoresho burashobora kugenwa kandi uburyo bumwe bufatika butangwa hano.
- Niba hakenewe ubunyangamugayo bwambere hejuru ya 0.1% hamwe nubushuhe bwubushyuhe bwa 25ppm, hakenewe guhitamo ubwoko bwumubyigano wa voltage.
- Niba ibikorwa byo hasi cyane bikenewe, noneho hagomba guhitamo icyerekezo cya voltage.
- Hagomba kwitonderwa mugihe ukoresheje parallel parallel voltage hamwe na voltage yagutse cyangwa imitwaro minini yingufu.Wemeze kubara agaciro kateganijwe kububasha bwatatanye, bushobora kuba burenze kure urukurikirane rwa voltage yerekanwe hamwe nibikorwa bimwe (reba urugero hepfo).
- Kubisabwa aho amashanyarazi atangwa ari hejuru ya 40V, parallel parallel voltage ishobora kuba inzira yonyine.
- Kuringaniza imbaraga za voltage zifatwa mubisanzwe iyo zubaka amashanyarazi atagabanije, kugenzura isi ireremba hejuru, gukuramo imirongo, cyangwa kugabanya imiyoboro.
Ibyerekeye Ibicuruzwa
TL431LI / TL432LI ni pin-to-pin ubundi buryo bwa TL431 / TL432.TL43xLI itanga ituze ryiza, ubushyuhe bwo hasi (VI (dev)), hamwe nibisobanuro biri hasi (Iref) kugirango sisitemu ibe nziza.
Ibikoresho bya TL431 na TL432 nuburyo butatu bushobora guhindurwa shunt, hamwe nubushyuhe bwihariye bwumuriro hejuru yubushyuhe bwimodoka, ubucuruzi, nubusirikare.Ibisohoka voltage irashobora gushirwa kubiciro byose hagati ya Vref (hafi 2,5 V) na 36 V, hamwe na rezo ebyiri zo hanze.Ibi bikoresho bifite umusaruro usanzwe wa 0.2 Ω.Ibisohoka bikora neza bitanga uburyo bukomeye bwo gufungura ibintu, bigatuma ibyo bikoresho bisimburwa neza na diode ya Zener mubisabwa byinshi, nko kugenzura ubwato, gutanga amashanyarazi, no guhindura amashanyarazi.Igikoresho cya TL432 gifite imikorere imwe nuburyo bwihariye bwamashanyarazi nkigikoresho cya TL431, ariko gifite pinout zitandukanye kubikoresho bya DBV, DBZ, na PK.
Ibikoresho byombi bya TL431 na TL432 bitangwa mu byiciro bitatu, hamwe no kwihanganira kwambere (kuri 25 ° C) bya 0.5%, 1%, na 2%, kuri B, A, nicyiciro gisanzwe.Mubyongeyeho, umusaruro muke ugabanuka nubushyuhe butuma umutekano uhinduka hejuru yubushyuhe bwose.
Ibikoresho bya TL43xxC birangwa no gukora kuva kuri 0 ° C kugeza kuri 70 ° C, ibikoresho bya TL43xxI birangwa no gukora kuva kuri 40 ° C kugeza kuri 85 ° C, naho ibikoresho bya TL43xxQ birangwa no gukora kuva kuri 40 ° C kugeza kuri 125 ° C. .
