ʻO ka TL431LI / TL432LI nā mea koho pin-to-pin
i TL431 / TL432.Hāʻawi ʻo TL43xLI i ka paʻa maikaʻi,
haʻahaʻa haʻahaʻa wela (VI(dev)), a haʻahaʻa

ʻO nā mea hana TL431 a me TL432 he ʻekolu-terminal
nā mea hoʻoponopono shunt hiki ke hoʻololi, me ka wela i ʻōlelo ʻia
paʻa ma luna o ka automotive pili, kalepa, a
pūʻali wela wela.Hiki i ka volta puka
e hoʻonoho i kekahi waiwai ma waena o Vref (ma kahi o
2.5 V) a me 36 V, me ʻelua mau pale kūwaho.
Loaʻa kēia mau mea hana i kahi impedance puka maʻamau
o 0.2 Ω.Hāʻawi ka circuitry output ikaika i kahi mea nui loa
ʻoi aku ka hoʻohuli ʻana i ke ʻano, hana i kēia mau mea hana
nā pani maikaʻi loa no nā diodes Zener i nā mea he nui
nā noi, e like me ka hoʻoponopono onboard, hiki ke hoʻololi
nā lako mana, a me nā lako mana hoʻololi.ʻO ka
TL432 mea like like 'ole ka hana a
nā kikoʻī uila e like me ka mea TL431, akā loaʻa

Hoʻohālikelike ʻia nā mea hana TL43xxC no ka hana
mai ka 0°C a hiki i ka 70°C, nā mea hana TL43xxI
ʻike ʻia no ka hana ʻana mai -40 ° C a i 85 ° C, a
ʻike ʻia nā mea hana TL43xxQ no ka hana
