ISO7021DR Digital Isolators Mana haʻahaʻa haʻahaʻa ATEX/IECEx-hōʻoia ʻelua-kanal digital isolator 8-SOIC

ʻO ka mea ISO7021 kahi mana ultra-haʻahaʻa, multichannel digital isolator hiki ke hoʻohana ʻia e hoʻokaʻawale i ka CMOS a i ʻole LVCMOS digital I/Os. Loaʻa i kēlā me kēia kaila hoʻokaʻawale kahi hoʻokomo loiloi a me ka hoʻopuka puka i hoʻokaʻawale ʻia e kahi pāpālua capacitive silicon dioxide (SiO2). ʻO ka hoʻolālā hoʻolālā e pili ana i ka ʻaoʻao hou i hui pū ʻia me kahi hoʻolālā modulation keying ON-OFF e hiki ai i kēia mau mea hoʻokaʻawale ke hoʻopau i ka mana haʻahaʻa loa i ka wā e hālāwai ana i ka helu kaʻawale 3000-VRMS no UL1577. Aia ma lalo o 120 μA/Mbps ka hoʻohana ʻana o kēlā me kēia channel static i kēia manawa ma 4.8 μA ma 3.3 V, e ʻae ana i ka hoʻohana ʻana i ka ISO7021 i nā mana a me nā hoʻolālā ʻōnaehana thermal constrained.

Hiki i ka mea hana ke hana ma lalo o ka 1.71 V, e like me ke kiʻekiʻe o 5.5 V, a paʻa i ka hana me nā volt hāʻawi like ʻole ma kēlā me kēia ʻaoʻao o ka pale kaʻawale. Hele mai ka mea hoʻokaʻawale ʻelua i loko o kahi pūʻolo 8-SOIC kino haʻiki me hoʻokahi ala i mua a me hoʻokahi kaila kuhikuhi hope i loko o kahi pūʻolo 8-SOIC. Loaʻa i ka hāmeʻa nā koho kiʻekiʻe a haʻahaʻa. Inā nalowale ka mana hoʻokomo a i ʻole ka hōʻailona, ​​ua kiʻekiʻe ka hoʻopuka paʻamau no ka mea ISO7021 me ka ʻole o ka suffix F a me ka haʻahaʻa no ka mea ISO7021F me ka suffix F. E ʻike i ka ʻaoʻao ʻo Device Functional Modes no ka ʻike hou aku.
