TL431, TL432 Igenamigambi risobanutse neza
1 Ibiranga
• Reba kwihanganira voltage kuri 25 ° C.
- 0.5% (B urwego)
- 1% (A amanota)
- 2% (Urwego rusanzwe)
• Guhindura ibisohoka voltage: Vref kugeza 36 V.
• Gukora kuva kuri −40 ° C kugeza kuri 125 ° C.
• Ubushyuhe busanzwe (TL43xB)
- mV 6 (C temp)
- 14 mV (I temp, Q temp)
• Urusaku ruto rusohoka
• 0.2-output Ibisohoka bisanzwe
• Ubushobozi bwo kurohama: 1 mA kugeza 100 mA
2 Porogaramu
• Guhindura imbaraga za voltage hamwe nubu
• Igice cya kabiri cyateganijwe muri SMPSs
• Gusimbuza Zener

3 Ibisobanuro
TL431LI / TL432LI ni pin-to-pin ubundi buryo
kuri TL431 / TL432.TL43xLI itanga ituze ryiza,
ubushyuhe bwo hasi bugabanuka (VI (dev)), no hepfo
icyerekezo kigezweho (Iref) kuri sisitemu yatezimbere
Ukuri.
Ibikoresho bya TL431 na TL432 ni bitatu
Guhindura shunt kugenzura, hamwe nubushyuhe bwihariye
ituze hejuru yimodoka ikoreshwa, ubucuruzi, na
ubushyuhe bwa gisirikare buringaniye.Ibisohoka voltage irashobora
shyirwa ku gaciro icyo ari cyo cyose hagati ya Vref (hafi
2.5 V) na 36 V, hamwe na rezo ebyiri zo hanze.
Ibi bikoresho bifite ibyasohotse bisanzwe
ya 0.2 Ω.Ibikorwa bisohoka byumuzunguruko bitanga cyane
gufungura cyane kuranga, gukora ibi bikoresho
abasimbuye beza kuri Zener diode muri benshi
Porogaramu, nk'Ibibaho, birashobora guhinduka
ibikoresho by'amashanyarazi, no guhindura amashanyarazi.Uwiteka
Igikoresho cya TL432 gifite imikorere imwe kandi
amashanyarazi asobanura nkigikoresho cya TL431, ariko afite
pinout zitandukanye kuri DBV, DBZ, na PK.
Ibikoresho byombi bya TL431 na TL432 byatanzwe muri
amanota atatu, hamwe no kwihanganira kwambere (kuri 25 ° C) ya
0.5%, 1%, na 2%, kuri B, A, nibisanzwe
amanota.Mubyongeyeho, ibisohoka bike drift na
ubushyuhe butuma umutekano uhinduka muri byose
ubushyuhe.
Ibikoresho bya TL43xxC birangwa no gukora
kuva 0 ° C kugeza 70 ° C, ibikoresho bya TL43xxI ni
irangwa no gukora kuva kuri 40 ° C kugeza 85 ° C, na
ibikoresho bya TL43xxQ birangwa no gukora
kuva kuri 40 ° C kugeza kuri 125 ° C.
