♠ ISO722x Dual-Channel Digital Isolators

ʻO nā polokalamu ʻohana ISO7220x a me ISO7221x nā mea hoʻokaʻawale kikohoʻe pālua.No ka hoʻomaʻamaʻa ʻana i ka hoʻolālā PCB, ua kuhikuhi ʻia nā kahawai ma ka ʻaoʻao like i ka ISO7220x a ma nā ʻaoʻao ʻē aʻe i ka ISO7221x.Loaʻa i kēia mau hāmeʻa kahi hoʻokomo loiloi a me ka pahu hoʻopuka puka i hoʻokaʻawale ʻia e ka silicon-dioxide (SiO2) kaawale ʻana o TI, e hāʻawi ana i kahi kaʻawale galvanic a hiki i 4000 VPK no VDE.Hoʻohana pū ʻia me nā lako mana hoʻokaʻawale, ua pāpā kēia mau mea i ka volta kiʻekiʻe a hoʻokaʻawale i nā kahua, a me ka pale ʻana i ka leo o ka leo ma kahi kaʻa kaʻa ʻikepili a i ʻole nā ​​​​kaapuni ʻē aʻe mai ke komo ʻana i ka ʻāina kūloko a keakea a hōʻino paha i ka circuit sensitive.

Hoʻonohonoho ʻia kahi hōʻailona hoʻokomo binary, unuhi ʻia i kahi hōʻailona kaulike, a laila hoʻokaʻawale ʻia e ka capacitive isolation barrier.Ma kahi o ka pale kaʻawale, loaʻa i ka mea hoʻohālikelike ʻokoʻa ka ʻike hoʻololi loiloi, a laila hoʻonohonoho a hoʻonohonoho hou i kahi flip-flop a me ke kaapuni puka e like me ia.Hoʻouna ʻia kahi pulse hōʻano hou ma waena o ka pale e hōʻoia i ka pae dc kūpono o ka puka.Inā ʻaʻole i loaʻa kēia puʻupuʻu dc-refresh i kēlā me kēia 4 μs, manaʻo ʻia ʻaʻole i hoʻohana ʻia ka hoʻokomo ʻana a ʻaʻole i hoʻoikaika ikaika ʻia, a ʻo ke kaapuni failsafe e alakaʻi i ka hopena i kahi kūlana kiʻekiʻe.

ʻO ka capacitance liʻiliʻi a me ka manawa hopena e hāʻawi i ka hana wikiwiki me nā helu hōʻailona i loaʻa mai ka 0 Mbps (DC) a i ka 150 Mbps (ʻO ka helu hōʻailona o kahi laina ka helu o nā hoʻololi uila i hana ʻia i kēlā me kēia kekona i hōʻike ʻia ma nā ʻāpana bps).Loaʻa i nā hāmeʻa Aoption, B-option, a me C-option nā paepae hoʻokomo TTL a me kahi kānana walaʻau ma ka hoʻokomo e pale ai i nā pulse transient mai ka hāʻawi ʻana i ka puka o ka hāmeʻa.Loaʻa i nā mea M-koho nā paepae hoʻokomo CMOS VCC/2 a ʻaʻohe kānana leo hoʻokomo a me ka lohi hoʻolaha hou.

ʻO ka ʻohana ISO7220x a me ISO7221x o nā mea pono e koi aku i ʻelua mau uila lako o 2.8 V (C-Grade), 3.3 V, 5 V, a i ʻole kekahi hui.ʻO nā mea hoʻokomo āpau he 5-V hoʻomanawanui ke hoʻolako ʻia mai kahi lako 2.8-V a i ʻole 3.3-V a ʻo nā mea hoʻopuka āpau he 4-mA CMOS.Hōʻike ʻia ka ʻohana ISO7220x a me ISO7221x no ka hana ʻana ma luna o ka pae wela ambient o -40°C a +125°C.
