ʻO ka TL431LI / TL432LI nā mea ʻokoʻa pin-to-pin i TL431 / TL432.Hāʻawi ʻo TL43xLI i ka paʻa ʻoi aku ka maikaʻi, ka haʻahaʻa haʻahaʻa haʻahaʻa (VI(dev)), a me ka haʻahaʻa haʻahaʻa o kēia manawa (Iref) no ka hoʻomaikaʻi ʻana i ka ʻōnaehana pololei.
ʻO nā hāmeʻa TL431 a me TL432 he mau mea hoʻoponopono shunt hiki ke hoʻololi ʻia, me ke kūpaʻa wela i ʻōlelo ʻia ma luna o nā pae wela o ka automotive, kalepa, a me ka pūʻali koa.Hiki ke hoʻonohonoho ʻia ka volta hoʻopuka i kekahi waiwai ma waena o Vref (ma kahi o 2.5 V) a me 36 V, me ʻelua mau pale kūwaho.Loaʻa i kēia mau mea i kahi impedance puka maʻamau o 0.2 Ω. Hāʻawi ka circuitry output ikaika i kahi hiʻohiʻona ʻoi loa, e hana ana i kēia mau mea hoʻololi maikaʻi loa no nā diodes Zener i nā noi he nui, e like me ka hoʻoponopono ma luna o ka moku, nā lako mana hiki ke hoʻololi ʻia, a me nā lako mana hoʻololi.Loaʻa i ka mea TL432 nā hana like a me nā kikoʻī uila e like me ka mea TL431, akā loaʻa nā pinout ʻokoʻa no nā pūʻolo DBV, DBZ, a me PK.
