Chip TL431 datasheet: tsananguro, izita, nokurondedzerwa

Chip TL431 datasheet Zvisinei akasikwa mukupera 70s, uye nhasi chichiri kushandiswa redhiyo mabasa mudzidzi uye indasitiri. Chip ichi chinhu chinokosha gozvo stabilizer kuti rave kushandiswa chaizvo siyana magetsi.

basa Description

TL431 datasheet ane nembambo matatu chete, asi zvakavanzika transistors gumi (comparator) wayo dzimba. Mashandiro anoita mudziyo uye kwakajairika stabilizer zvakafanana. Zvisinei, nokuda matambudziko akadaro, chip fari ane yakakwirira chafariz isimbe, uye nani kuoma unhu. The chikuru chinoratidza zano rakadaro ndiko kugona kushandisa mugoveri kuchinja kwokunze voltage Kudzikamiswa mukati 2.5-30 V. Vamwe mienzaniso nechepazasi muganhu kungava 1.25 V. The comparator redunhu kuti revatema kupinda chigadzirwa datasheet TL431, inoumbwa nezvinhu zvinotevera:

• Integrated simba (chaizvo kugadzikana) bhuku voltage 2.5 V, riri kubata kune Ivan Kuchin mazano ari comparator;
• zvakananga chiyamuro chechetere;
• ari comparator goho transistor, kuti emitter uye nomuteresi iro ikashandiswa pamwe nesimba contactsGoogle;
• mumwe diode kudzivirira polarity chaisazvitsigira.

The transistor ane kunonyanyisa mutoro 100 Ma uye vaifanira voltage pamusoro - 36 V. Kuti vapinze munhu comparator yakavakwa muna (azvaitwa akazarura panguva goho transistor chip) zvinoda pamusoro wayo chiyamuro ikwidzwe voltage kupfuura nezvezvinotaurwa. Kuverengerwa mugwaro Chip chiyamuro voltage mugoveri zvinosanganisira resistors maviri, inokamura iri hafu voltage ukoshi. Izvi zvinoreva kuti comparator achaita kana kupinda mazano redunhu 5, kuti goho ari mugoveri kuwana 2,5 V. Kana resistor kuwedzera nemishonga, zvakakodzera kunowedzerawo uye voltage rive. Zvakaratidza kuti dunhu iri rinogona kushanda sechinhu zener diode mukati 2,5-36 V.

Purpose uye Makuriro

Hapana chete kombiyuta simba wedzerai Unit, umo makanga musina Chips TL431 datasheet. Uyewo, unogona kuwanika zvinenge zvose pasi-simba pulsed magetsi, somuenzaniso, uchiraira kuti maserura. chip izvi zvinogona kushandiswa kwete chete kuti chinangwa chahwo (zener diode simba nerubatsiro anokwana zviyero), asiwo kusika kwavo maererano vezviedza siyana uye anzwike okuzvidzivirira. With mano aya kuongorora mumwe muzvizhinji kuti parameters dzakasiyana (asi chikuru voltage iri). Kune zvirongwa zvakawanda inobva TL431 datasheet, kuburikidza icho zvinokwanisika akakokera mudziyo Panyaya nemvura dhigiri mudziyo, mwando tembiricha, gasi kumanikidzwa kana mvura mvura illuminance. Dzakanyorwa nzira - zvisingaiti chete, kushandiswa Chip izvi chaizvoizvo kwazvo, zvose zvinoenderana kuda akagadzira.

Kakawanda, beginners redhiyo amateurs kuziva chii chinogona yatsiviwa TL431. Analogue Chokwadi, dziripo. Saka, unogona kushandisa kupinza uye mudzimba zvigadzirwa KA431 KR142EN19A mudziyo K1156ER5h.

To muchidimbu

Revatema redunhu "TEXAS zviridzwa" makambani yakavimbika zvikuru, ine upamhi uchishandisa siyana, nyore kushandisa, uye Chikurukuru, ane inokwanisika mutengo. Nokuda zvachiri, inobereka makore anopfuura makumi mana uye kachiri.
