Zotsatira

Udindo wa ma voltage reference chips.

M'kati mwazomwe zikugwiritsidwa ntchito pakalipano, kulondola kwa chipangizo chamagetsi chamagetsi (kusiyana kwa mtengo wamagetsi, kuyendetsa, kusintha kwamakono, ndi zizindikiro zina) ndikwabwino kwambiri kuposa zen regulator diode kapena zitatu-terminal regulator, Chifukwa chake imagwiritsidwa ntchito pakufunika kwa voteji yolondola kwambiri ngati voteji, nthawi zambiri ya A/D, D/A, ndi gwero lamagetsi olondola kwambiri, komanso mabwalo ena owunikira magetsi amagwiritsanso ntchito gwero lamagetsi.

Gulu

Kugawika kwa ma voltage reference chips.
Malinga ndi zomwe zafotokozedwera mkati, mawonekedwe amagetsi amagetsi ndi osiyana, ma voliyumu amagawika m'magulu awiri a bandgap voltage regulator.Band gap voltage reference structure ndi njira ya PN yotsamira kutsogolo ndi voteji yomwe imagwirizanitsidwa ndi VT (kuthekera kwa kutentha) motsatizana, pogwiritsa ntchito kutentha kwapakati pa PN junction ndi kutentha kwabwino kwa VT offset kuti akwaniritse chipukuta misozi.Dongosolo la regulator voltage reference ndi njira yolumikizira kagawo kakang'ono ka sub-surface breakdown regulator ndi gawo la PN, pogwiritsa ntchito kutentha kwabwino kwa owongolera ndi kutentha koyipa kwa gawo la PN kuti aletse chipukuta misozi.Kuwonongeka kwapansi pamunsi kumathandiza kuchepetsa phokoso.Mphamvu yamagetsi yamtundu wa chubu yamagetsi ndi apamwamba (pafupifupi 7V);mphamvu yamagetsi yamagetsi a bandgap ndiyotsika, kotero yotsirizirayi imagwiritsidwa ntchito kwambiri pomwe ma voltages otsika amafunikira.
Kutengera ndi mawonekedwe akunja, ma voliyumu amagawidwa m'magulu awiri: mndandanda ndi ofanana.Akagwiritsidwa ntchito, maumboni angapo amagetsi amafanana ndi magetsi oyendetsedwa ndi ma terminal atatu, pomwe voteji yolumikizira imalumikizidwa motsatizana ndi katundu;ma parallel voltage amafanana ndi ma voltage regulators, pomwe voteji yolumikizira imalumikizidwa limodzi ndi katundu.Magawo awiri a band gap voltage ndi machubu ma voltage angagwiritsidwe ntchito pamasinthidwe awiriwa.Ubwino wa maumboni amagetsi otsatizana ndikuti amangofunika zolowetsamo kuti apereke chiwongolero cha chip ndikupereka katundu wapano pomwe katunduyo alipo;maumboni amagetsi ofananira amafuna kuti kukondera kwapano kukhale kokulirapo kuposa kuchuluka kwaposachedwa kwa chip komanso kuchuluka kwa katundu wapano ndipo sizoyenera kugwiritsa ntchito mphamvu zochepa.Ubwino wa ma parallel voltage reference ndikuti ndiwokondera, amatha kutengera ma voltages osiyanasiyana olowera, ndipo ndi oyenera kugwiritsidwa ntchito ngati ma voliyumu oyimitsidwa.

Kusankha

Kusankhidwa kwa mndandanda wamagetsi amtundu wamagetsi ndi chip chofanana chamagetsi
Mndandanda wamagetsi wamagetsi uli ndi ma terminals atatu: VIN, VOUT, ndi GND, ofanana ndi mzere wowongolera, koma wokhala ndi zotulutsa zochepa komanso zolondola kwambiri.Series voteji maumboni structural olumikizidwa ku mndandanda ndi katundu (Chithunzi 1) ndipo angagwiritsidwe ntchito ngati voteji-ankalamulira resistor yomwe ili pakati pa VIN ndi VOUT terminals.Posintha kukana kwake kwamkati, kusiyana pakati pa mtengo wa VIN ndi kutsika kwa voliyumu kudutsa chopinga chamkati (chofanana ndi voliyumu ya VOUT) kumakhazikika.Popeza pakali pano ndikofunikira kuti pakhale kutsika kwamagetsi, chipangizocho chimayenera kujambula pang'ono pang'ono kuti chitsimikizire kuwongolera kwamagetsi popanda katundu.Zolozera zamagetsi zolumikizidwa ndi Series zili ndi izi.
- Magetsi operekera (VCC) ayenera kukhala okwera mokwanira kuti awonetsetse kutsika kwamagetsi okwanira pamagetsi amkati, koma voteji yokwera kwambiri imatha kuwononga chipangizocho.
- Chipangizocho ndi phukusi lake liyenera kusokoneza mphamvu ya chubu chowongolera.
- Popanda katundu, mphamvu yokhayo yotayika ndi mphamvu yamagetsi yamagetsi.
- Magawo amagetsi amtundu nthawi zambiri amakhala ndi zolakwika zoyambira komanso kutentha kofananira kuposa ma voteji ofanana.

The parallel voltage reference ili ndi ma terminals awiri: OUT ndi GND.Ndizofanana kwenikweni ndi diode yowongolera voteji koma ili ndi mawonekedwe abwinoko owongolera voteji, ofanana ndi diode yowongolera voteji yomwe imafuna chopinga chakunja ndikugwira ntchito molingana ndi katundu (Chithunzi 2).The parallel voltage reference ingagwiritsidwe ntchito ngati gwero lamakono loyendetsedwa ndi voteji lomwe limalumikizidwa pakati pa OUT ndi GND, posintha mphamvu yamkati kuti kusiyana pakati pa voteji yoperekera ndi kutsika kwa voteji pa resistor R1 (yofanana ndi voteji yofananira ku OUT) kukhalebe. khola.Mwanjira ina, mtundu wofananira wa voteji umasunga voteji nthawi zonse ku OUT posunga kuchuluka kwa katundu wapano ndi zomwe zikuyenda nthawi zonse.Mitundu yofananira ili ndi izi.
- Kusankhidwa kwa R1 yoyenera kumatsimikizira kuti zofunikira zamagetsi zimakwaniritsidwa ndipo kufotokozera kwamtundu wofananirako kulibe malire pamagetsi owonjezera.
- Zomwe zimaperekedwa ndizomwe zimaperekedwa ndizodziyimira pawokha komanso zomwe zikuyenda pakalipano ndipo zomwe zikunenedwazo zimayenera kutulutsa kutsika kwamagetsi koyenera kudutsa resistor R1 kuti asunge voteji ya OUT nthawi zonse.
- Monga zida zosavuta za 2-terminal, maumboni amagetsi ofananira amatha kusinthidwa kukhala mabwalo atsopano monga zowongolera ma voltage negative, zowongolera pansi zoyandama, mabwalo odulira, ndi mabwalo ochepetsa.
- Mawonekedwe amagetsi ofananira amakhala ndi mphamvu yocheperako kuposa ma voltages angapo.
Kusiyana pakati pa mndandanda ndi maumboni amagetsi ofananirako kumveka, chipangizo choyenera kwambiri chitha kusankhidwa kuti chigwiritse ntchito.Kuti mupeze chipangizo choyenera kwambiri, ndi bwino kuganizira mndandanda ndi maumboni ofanana.Magawo amitundu yonseyo akawerengedwa mwachindunji, mtundu wa chipangizocho ukhoza kuzindikirika ndipo njira zina zoyeserera zimaperekedwa apa.
- Ngati kulondola koyambirira kopitilira 0.1% ndi kutentha kwa 25ppm kumafunika, mtundu wamtundu wamagetsi uyenera kusankhidwa nthawi zambiri.
- Ngati ntchito yotsika kwambiri ikufunika, ndiye kuti mawu ofananirako amayenera kusankhidwa.
- Chisamaliro chiyenera kutengedwa mukamagwiritsa ntchito ma voltages ofananira okhala ndi ma voltages ambiri kapena katundu wamkulu wamphamvu.Onetsetsani kuti mwawerengera mtengo woyembekezeka wa mphamvu yotayidwa, yomwe ingakhale yokwera kwambiri kuposa ma voliyumu angapo omwe ali ndi ntchito yofanana (onani chitsanzo pansipa).
- Pazinthu zomwe magetsi operekera ali pamwamba pa 40V, njira yokhayo yolumikizira magetsi yofananira ndiyo njira yokhayo.
- Mawonekedwe amagetsi ofananira nthawi zambiri amaganiziridwa pomanga zowongolera ma voltage olakwika, zowongolera pansi zoyandama, mabwalo odulira, kapena mabwalo ochepetsa.

Za Mankhwala

TL431LI / TL432LI ndi njira zina zosinthira TL431 / TL432.TL43xLI imapereka kukhazikika kwabwinoko, kutsika kwa kutentha (VI(dev)), komanso kutsika kwapano (Iref) pakuwongolera makina olondola.
Zipangizo za TL431 ndi TL432 ndi zowongolera zosinthika zitatu, zokhala ndi kukhazikika kwapadera kwamafuta pamagalimoto, malonda, ndi kutentha kwankhondo.Mphamvu yotulutsa imatha kukhazikitsidwa pamtengo uliwonse pakati pa Vref (pafupifupi 2.5 V) ndi 36 V, yokhala ndi zopinga ziwiri zakunja.Zidazi zimakhala ndi vuto la 0.2 Ω.Active output circuitry imapereka mawonekedwe akuthwa kwambiri, kupangitsa kuti zidazi zikhale zabwino kwambiri m'malo mwa Zener diode pamapulogalamu ambiri, monga ma onboard regulation, magetsi osinthika, ndikusintha magetsi.Chipangizo cha TL432 chili ndi magwiridwe antchito ofanana ndendende ndi mawonekedwe amagetsi monga chipangizo cha TL431, koma chili ndi ma pinouts osiyanasiyana a phukusi la DBV, DBZ, ndi PK.
Zida zonse za TL431 ndi TL432 zimaperekedwa m'makalasi atatu, ndi kulolera koyambirira (pa 25 ° C) kwa 0.5%, 1%, ndi 2%, kwa B, A, ndi kalasi yokhazikika, motsatana.Kuphatikiza apo, kutsika kwapang'onopang'ono poyerekeza ndi kutentha kumatsimikizira kukhazikika kwanyengo yonse ya kutentha.
Zipangizo za TL43xxC zimadziwika kuti zimagwira ntchito kuyambira 0 ° C mpaka 70 ° C, zida za TL43xxI zimadziwika kuti zimagwira ntchito kuyambira -40 ° C mpaka 85 ° C, ndipo zida za TL43xxQ zimadziwika kuti zimagwira ntchito kuyambira -40 ° C mpaka 125 ° C. .
