3 Inkcazo
I-TL431LI / TL432LI zezinye iindlela ze-pin-to-pin
ukuba TL431 / TL432.I-TL43xLI inikeza uzinzo olungcono,
ubushushu obuphantsi drift (VI(dev)), kwaye busezantsi
ireferensi yangoku (Iref) yenkqubo ephuculweyo
ukuchaneka.
Izixhobo ze-TL431 kunye ne-TL432 zi-terminal ezintathu
abalawuli shunt adjustable, kunye thermal echaziweyo
uzinzo phezu kweemoto ezifanelekileyo, urhwebo, kunye
amanqanaba obushushu bomkhosi.Umbane wemveliso unako
ibekwe kulo naliphi na ixabiso phakathi kweVref (malunga
2.5 V) kunye ne-36 V, kunye ne-resistors ezimbini zangaphandle.
Ezi zixhobo zine-impedance yemveliso eqhelekileyo
ye 0.2 Ω.Imveliso yesekethe esebenzayo ibonelela kakhulu
uphawu olubukhali lokujika, ukwenza ezi zixhobo
ukutshintshwa okugqwesileyo kweediode zeZener kwiindawo ezininzi
izicelo, ezinje ngolawulo lwebhodi, ezinokuhlengahlengiswa
izixhobo zombane, kunye nokutshintsha izixhobo zombane.I
Isixhobo se-TL432 sinokusebenza okufanayo kunye
iinkcukacha zombane njengesixhobo TL431, kodwa iye
iipinouts ezahlukeneyo zeDBV, DBZ, kunye neepakethe zePK.
Zombini izixhobo ze-TL431 kunye ne-TL432 zibonelelwa kuyo
amabanga amathathu, kunye nokunyamezela kokuqala (kuma-25 ° C) we
0.5%, 1%, kunye 2%, ku-B, A, kunye nomgangatho
ibakala, ngokulandelelanayo.Ukongeza, isiphumo esisezantsi sokukhukuliseka ngokuchasene
ubushushu buqinisekisa uzinzo olulungileyo kulo lonke
uluhlu lobushushu.
Izixhobo zeTL43xxC ziphawulwe ukusebenza
ukusuka 0 ° C ukuya 70 ° C, izixhobo TL43xxI
eziphawulelwe ukusebenza ukusuka -40 °C ukuya 85 °C, kunye
izixhobo TL43xxQ ziphawulwe ukusebenza
ukusuka ku-40°C ukuya kwi-125°C.
