Nti TL431 datasheet: hauj lwm, los, specifications

Nti TL431 datasheet tsim nyob rau hauv lub lig 70s, txawm li cas los, thiab niaj hnub no nws yog dav siv nyob rau hauv pib xyaum ua xov tooj cua ua ub no thiab kev lag luam. Qhov no nti yog ib kauj stabilizer uas tau lug siv nyob rau hauv ntau yam khoom siv fais fab.

txoj hauj lwm hauj lwm

TL431 datasheet muaj tsuas yog peb pins, tab sis muab zais kaum transistors (comparator) nyob rau hauv nws vaj tse nyob. Lub zog ntawm cov ntaus ntawv thiab ib tug pa stabilizer zoo sib xws. Txawm li cas los, vim rau tej teeb meem, lub nti muaj ib tug ntau dua thermal stability, thiab paub toughness yam ntxwv. Lub ntsiab feature ntawm xws li ib tug ntaus ntawv yog tus muaj peev xwm mus siv lub divider hloov lwm voltage stabilization hauv 2.5-30 V. Ib co ua qauv qis txwv tej zaum yuav 1.25 V. Cov comparator Circuit Court hais tias yog kev mus rau hauv cov khoom datasheet TL431, muaj cov nram qab no Cheebtsam:

• kev muaj hwj chim (ruaj khov heev) siv voltage 2.5 V, uas yog kev cob cog rua rau lub ntxeev tswv yim ntawm lub comparator;
• ib tug tib neeg cov tswv yim uas nws kawm;
• lub comparator tso zis transistor, lub emitter thiab collector ntawm uas yog ua ke nrog lub hwj chim hu;
• ib tug diode rau kev tiv thaiv tiv thaiv polarity reversal.

Lub transistor muaj ib tug tshaj plaws load ntawm 100 MA thiab ib tug tshaj plaws voltage ntawm - 36 V. Nyob rau hauv thiaj li yuav thauj ib tug ua-nyob rau hauv comparator (feem qhib thaum cov qhov tso zis transistor nti) yuav tsum tau nyob rau hauv nws cov tswv yim sau ib daim ntawv voltage siab tshaj cov kev siv. Muaj nyob rau hauv lub nti tswv yim voltage divider muaj ob resistors, nws faib nyob rau hauv ib nrab ntawm cov voltage nqi. Qhov no txhais tau tias lub comparator yuav thaum nkag mus kawm rau hauv lub tswv yim Circuit Court 5, tso zis hauv lub divider tau 2.5 V. Yog hais tias resistor ua rau kom cov kuj, nws yog tsim nyog los kuj nce thiab cov voltage mov. Nws hloov tawm hais tias qhov no Circuit Court yuav ua hauj lwm raws li ib tug zener diode hauv 2,5-36 V.

Lub hom phiaj thiab Scope

Yog tsis muaj ib lub computer fais fab mov unit, nyob rau hauv uas muaj muaj tsis muaj tej daim TL431 datasheet. Tsis tas li ntawd, nws muaj peev xwm yuav nrhiav tau nyob rau hauv yuav luag tag nrho cov muaj hwj huam pulsed khoom siv fais fab, piv txwv li, them rau cov xov tooj txawb. Cov chips yuav siv tsis tau tsuas yog rau nws npaj lub hom phiaj (zener diode rau fais fab mov units), tab sis kuj yuav tsim nyob rau hauv lawv lub hauv paus ntawm ntau yam teeb thiab audible alarms. Nrog rau cov pab kiag li lawm saib xyuas ib tug plurality ntawm txawv tsis (tab sis tseem yooj yim voltage yog). Muaj ntau ntau schemes raws li TL431 datasheet, los ntawm kev uas nws tseem tau los sib sau ua ke rau hauv lub ntaus ntawv rau kev tswj cov kua theem nyob rau hauv cov hlab, cov av noo thiab qhov kub thiab txias, roj siab los yog kua illuminance. Yog kev xaiv - tsis tsuas tau, siv ntawm no nti ua tau zoo heev, nws tag nrho cov nyob rau hauv lub kam ntawm cov designer.

Heev feem ntau, beginners xov tooj cua amateurs xav nyob rau hauv dab tsi yuav los hloov tus TL431. Analogue, ntawm chav kawm, nyob ua ib ke. Yog li ntawd, koj siv tau cov mas thiab domestic khoom KA431 KR142EN19A ntaus K1156ER5h.

Yuav kom saib lub ntsab lug

Kev Circuit Court "Texas seev" tuam txhab uas muag yog heev txhim khu kev qha, nws muaj ib tug ntau kev khiav hauj lwm ntau yam, ib qho yooj yim mus siv, thiab tseem ceeb tshaj, muaj ib tug nqi pheej yig. Vim nws tus yam ntxwv, nws tsim tawm ntau tshaj plaub caug xyoo thiab yog tseem nrov.
