Chip TL431 datasheet: kufotokoza, akuti, specifications

Chip TL431 datasheet analengedwa mu 70s mochedwa Komabe, lero chimagwiritsidwa ntchito zinthu zofufuzafufuza wailesi komanso mafakitale. Chip Ichi ndi yofunika chiwongolero stabilizer kuti wakhala chimagwiritsidwa ntchito katundu osiyanasiyana mphamvu.

Kufotokozera ntchito

TL431 datasheet ali zikhomo atatu okha, koma zobisika transistors khumi (comparator) mu nyumba yake. Ntchito chipangizo ndi stabilizer ochiritsira ofanana. Komabe, chifukwa mavuto amenewa, Chip ali ndi kukhazikika apamwamba ikukhudzana ndi bwino makhalidwe kulimba. Mbali yaikulu ya chipangizo chotero ndi luso ntchito wogawira kusintha kunja voteji olimba mwa 2.5-30 V. ena zitsanzo m'munsi malire kungakhale 1,25 V. The comparator dera limene Integrated mu mankhwala datasheet TL431, tichipeza zigawo izi:

• Integrated mphamvu (khola kwambiri) Buku voteji 2.5 V, amene olumikizidwa kwa athandizira osiyanitsidwa wa comparator ya;
• lachindunji mlingo athandizira;
• ndi comparator linanena bungwe transistor, ndi emitter ndi wokhometsa amene amaphatikizidwa ndi kulankhula mphamvu;
• ndi diode kuti adziteteze polarity zitasintha.

The transistor ali ndi katundu pazipita 100 MA ndi voteji pazipita - 36 V. Kuti kutsegula anamanga-mu comparator (motero anatsegula pa linanena bungwe transistor Chip) imayenereza pa athandizira ake kupeleka voteji kuposa zolozerazo. Zina pa Chip athandizira voteji wogawira ongokhala resistors ziwiri, ukugawa mu theka mtengo voteji. Izi zikutanthauza kuti comparator adzakhala pamene adalowa athandizira dera 5, linanena bungwe la wogawira kupeza 2.5 V. Ngati resistor kuonjezera kukana, m'pofunika kuwonjezera ndi mwa kundipatsako voteji. Iwo likukhalira kuti dera lino akhoza ntchito zener diode mkati 2,5-36 V.

Cholinga ndi Mbali

Palibe umodzi kompyuta mphamvu kotunga wagawo, limene kunalibe datasheet tchipisi TL431. Komanso, angapezeke mu otsika mphamvu pulsed katundu pafupifupi mphamvu zonse, mwachitsanzo, nawuza kwa mafoni. tchipisi angagwiritsidwe ntchito osati kwa cholinga chake (zener diode kwa mayunitsi magetsi), komanso kulenga pa maziko awo a magetsi zosiyanasiyana ndi zizindikiro lomveka. Ndi zipangizo izi kuwunika ndi kuchuluka magawo osiyana (koma zofunika voteji ndi). Pali ziwembu zambiri zochokera TL431 datasheet, imene n'zotheka kuti asonkhane chipangizo kwa kulamulira mlingo madzi chotengeracho, chinyezi ndi kutentha, gasi kuthamanga kapena illuminance madzimadzi. Chipatso options - Zimatheka, ntchito Chip uwu uli makamaka bwino, izo zidalira pa kufunitsitsa kwa mlengi.

Nthawi zambiri, Amateurs oyamba wailesi chidwi zimene akhoza m'malo mwa TL431. Analogue Inde, alipo. Chotero, inu mukhoza ntchito kunja ndi zoweta mankhwala KA431 KR142EN19A chipangizo K1156ER5h.

kuti adzimvera

Integrated dera "Texas zida" makampani odalirika kwambiri, lili lonse opaleshoni osiyanasiyana, yosavuta kugwiritsa ntchito, ndipo ambiri Chofunika, ali ndi mtengo angagulidwe. Chifukwa makhalidwe ake, amabala zaka zoposa makumi anayi ndi akadali otchuka.
