Microcircuit TL431 datasheet: tlhaloso, morero, litsebi tsa theknoloji

TL431 datasheet chip e bōpiloe ho elella bofelong ba lilemo tsa bo-1970, empa ho fihlela kajeno e sebelisoa haholo ho batho ba sebelisang seea-le-moea le indasteri. Ena chip ke molao o hlophisehang o ka fetohang, o fumaneng tšebeliso e pharaletseng ka thepa e fapaneng ea matla.

Tlhaloso ea mosebetsi

TL431 datasheet e na le liphello tse tharo feela, empa tabeng ea eona li-transistors tse leshome li patehile. Mesebetsi ea sesebelisoa sena le se-stabilizer tse tloaelehileng li tšoana. Leha ho le joalo, ka lebaka la bothata bona, chip ena e na le boemo bo phahameng ba ho tsitsa, hammoho le marapo a eketsehileng a sebopeho. Ntho e ka sehloohong ea mochine ona ke matla a nang le mohlahloli oa ka ntle ho fetola mocheso o tsitsitseng ka hare ho meeli ea 2.5-30 V. Bakeng sa mefuta e meng e ka tlaase e ka ba 1.25 V. Potoloho ea comparator e kenyelelitsoe ho datasheet TL431 e na le likarolo tse latelang:

• Mohloli o tsitsitseng (o tsitsitseng) oa 2.5 V reference voltage, o amanang le boipheliso bo kenyelletsoeng;
• Puo e le 'ngoe ea boemo bo tobileng;
• Ho tsoa ho comparator, transistor, eo moemeli le moqokeleli ba kopantsoeng le metsoalle ea matla;
• Tšoaea bakeng sa tšireletso khahlanong le polarity e fapaneng.

Transistor e na le boima bo boholo ba meriana ea 100 mA, le matla a phahameng a 36 V. E le hore motšoantšisi ea hahiloeng a sebetse (ka tsela e lumellanang, transistor e hlahisoang ke microchip e qala), ho hlokahala O ho kenya letsoho ho sebelisa matla a mahlaseli ka holim'a reference. Ha ho kenngoa palo ho kenyeletsa motlakase oa motlakase, o nang le li-resistor tse peli, o arola mocheso ka halofo. Sena se bolela hore setšoantšo se tla buleha ha monehelo oa potoloho e le 5 V, ho tsoa ho phapang ea mo arohanyi, re fumana 2.5 V. Haeba u phahamisa khanyetso ea khanyetso, o tlameha ho eketsa le matla a phepelo. Ho bonahala eka sena se ka sebetsana e le sebopeho sa zener ka 2.5-36 V.

Morero le boholo ba kopo

Ha ho na matla a khomphutha a k'homphieutha a se nang TL431 datasheet chip. Hape e ka fumanoa hoo e batlang e le lisebelisoa tsohle tsa matla a tlaase a matla, ka mohlala, ho lefella lithelefono tsa cellular. Litlhapi tsena li ka sebelisoa eseng feela ka morero oa tsona (morero oa ho etsa matla a motlakase), empa hape ho theha lisebelisoa tse fapaneng tsa leseli le likhalase tse utloahalang. Ka thuso ea lisebelisoa tse joalo, mekhahlelo e fapaneng e fapaneng e hlahlojoa (empa e ka sehloohong e ntse e le mocheso). Ho na le merero e mengata e thehiloeng ho TL431 datasheet, ka lebaka la hore na ho khoneha ho bokella lisebelisoa tse laolang boemo ba metsi ka tanka, mongobo le mocheso, khase kapa khatello ea metsi, khanyang. Likgetho tse thathamisitsoeng ke tsona hase tsona feela tse ka khonehang, tshebeliso ea chip ena e hlile e le bophara haholo, ho itšetlehile ka takatso ea moqapi.

Hangata hangata batho ba nang le seea-le-moeeng ba thahasella se ka nkeloang sebaka ke TL431. Ha e le hantle, se tšoanang le sona se teng. Kahoo, hoa khoneha ho sebelisa lihlahisoa tse tsoang linaheng tse ling КА431 le lihlahisoa tsa malapeng КР142ЕН19А, К1156ЕР5х.

A re ke re akaretsa liphetho

Mochine o kopaneng oa khampani "TEXAS INSTRUMENTS" o ka tšeptjoa ka ho fetisisa, o na le mefuta e mengata ea ho sebetsa, e bonolo ho sebetsa, 'me ea bohlokoa ka ho fetisisa, e na le theko e theko e tlaase. Ka lebaka la litšoaneleho tsa eona, e hlahisoa lilemo tse fetang mashome a mararo 'me e sala e ntse e hlokahala.
