Mgbawa TL431 datasheet: nkọwa, designation, nkọwa

Mgbawa TL431 datasheet kere mbubreyo 70s, Otú ọ dị, na taa ọ na ọtụtụ-eji na-amu amu radio eme na ụlọ ọrụ. Nke a mgbawa bụ otu ihe n'iru stabilizer na e ọtụtụ-eji dị iche iche ike onunu.

ọrụ Description

TL431 datasheet nwere nanị atọ mkpọ, ma zoro iri transistors (comparator) na ya ụlọ. The ọrụ nke na ngwaọrụ na a ot stabilizer yiri. Otú ọ dị, n'ihi na ndị dị otú ahụ nsogbu, mgbawa nwere elu thermal kwụsie ike, na mma ike e ji mara. The isi mma nke ndị dị otú a ngwaọrụ bụ ikike iji ihe na divider ịgbanwe mpụga voltaji stabilization n'ime 2.5-30 V. Ụfọdụ ụdị ala ịgba nwere ike 1.25 V. The comparator circuit na na-ike n'ime ngwaahịa datasheet TL431, mejupụtara ndị na-esonụ components:

• integrated ike (nnọọ anụ) akwụkwọ voltaji 2.5 V, nke na jikọọ na inverse input nke comparator;
• a kpọmkwem input larịị;
• na comparator mmepụta transistor, na emitter na mkpoko nke na-achọkwa na-ike kọntaktị;
• a diode maka nchedo polarity agbanwe.

The transistor nwere a kacha ibu nke 100 MA na a kacha voltaji of - 36 V. Iji Ibu Ibu a wuru na-comparator (karị meghere na mmepụta transistor mgbawa) chọrọ na ya ọsọ ọsọ faịlụ a voltaji elu karịa akwụkwọ. Gụnyere na mgbawa input voltaji divider esịnede abụọ resistors, o kewara na ọkara voltaji uru. Nke a pụtara na comparator ga mgbe abanye input circuit 5, na mmepụta nke divider enweta 2.5 V. Ọ bụrụ resistor dịkwuo eguzogide, ọ dị mkpa iji na-amụbakwa na voltaji ọkọnọ. Ọ na-enyo na a circuit nwere ike na-arụ ọrụ dị ka a zener diode n'ime 2,5-36 V.

Nzube na Akporo

E nweghị otu kọmputa ike ọkọnọ unit, na nke a na-enweghị ibe TL431 datasheet. Ọzọkwa, ọ nwere ike dị na fọrọ nke nta niile dị ala-ike pulsed ike onunu, n'ihi na ihe atụ, odori maka mobile phones. A ibe nwere ike ji mee bụghị naanị n'ihi ya bipụta ya nzube (zener diode maka ike ọkọnọ nkeji), ma na-ike na ha ndabere nke dị iche iche ọkụ na nke Mkpu. Na ndị a ngwaọrụ nyochaa a plurality nke dị iche iche kwa (ma ka na-isi voltaji bụ). E nwere ọtụtụ atụmatụ dabeere TL431 datasheet, site na nke ọ bụ ike ka a kpọkọta ndị ngwaọrụ ịchịkwa mmiri mmiri larịị ke arịa na-iru mmiri na ọnọdụ okpomọkụ, gas nrụgide ma ọ bụ ọmụmụ illuminance. Edepụtara nhọrọ - bụghị nanị na o kwere omume, na ojiji nke a mgbawa bụ n'ezie nnọọ nke ọma, ya niile na-adabere na njikere nke mmebe.

Ọtụtụ mgbe, beginners radio enwechaghị ahụmahụ nwere mmasi ihe nwere ike dochie anya TL431. Analogue, n'ezie, adị. Ya mere, i nwere ike iji dị na anụ ụlọ ngwaahịa KA431 KR142EN19A ngwaọrụ K1156ER5h.
