I-TL431LI / TL432LI ezinye izindlela zokuphina-kuphin
ku-TL431/TL432.I-TL43xLI inikeza ukuzinza okungcono,
ukwehla kwezinga lokushisa eliphansi (VI(dev)), naphansi
ireferensi yamanje (Iref) yohlelo oluthuthukisiwe
ukunemba.
Amadivayisi we-TL431 kanye ne-TL432 anamatheminali amathathu
izilawuli ze-shunt eziguquguqukayo, ezine-thermal ecacisiwe
ukuzinza phezu kwezimoto ezisebenzayo, ezohwebo, kanye
amazinga okushisa ezempi.I-voltage ephumayo ingaba
isethwe kunoma yiliphi inani phakathi kwe-Vref (cishe
2.5 V) kanye no-36 V, okunezinto ezimbili eziphikisayo zangaphandle.
Lawa madivayisi ane-impedance evamile yokukhipha
kwe 0.2 Ω.I-Active output circuitry ihlinzeka kakhulu
isici esibukhali sokuvula, okwenza lezi zisetshenziswa
ukushintshwa okuhle kakhulu kwama-diode e-Zener kwabaningi
izinhlelo zokusebenza, njengokulawula okungaphakathi, okulungisekayo
izinsiza zikagesi, kanye nokushintsha izinto zikagesi.I
Idivayisi ye-TL432 inokusebenza okufanayo kanye
imininingwane kagesi njengedivayisi ye-TL431, kodwa ine
ama-pinouts ahlukene we-DBV, DBZ, kanye namaphakheji we-PK.
Kokubili amadivayisi we-TL431 kanye ne-TL432 ahlinzekwa ngaphakathi
amabanga amathathu, nokubekezelelana kokuqala (ku-25°C) ka
0.5%, 1%, kanye no-2%, we-B, A, kanye nezinga
ibanga, ngokulandelana.Ngaphezu kwalokho, i-drift ephansi ephumayo iqhathaniswa
izinga lokushisa liqinisekisa ukuzinza okuhle kulo lonke
izinga lokushisa.
Amadivayisi we-TL43xxC aphawulelwe ukusebenza
kusuka ku-0°C kuya ku-70°C, amadivaysi e-TL43xxI anjalo
ephawuleka ukusebenza kusuka -40°C kuya ku-85°C, futhi
amadivayisi we-TL43xxQ aphawulelwe ukusebenza
kusuka ku-40°C kuya ku-125°C.
