I-Iso7221cdr Ehlanganisiwe Yesekethe ye-IC Chip Entsha Futhi Yangempela

incazelo emfushane:

I-ISO7220x kanye ne-ISO7221x amadivayisi omndeni ayizihlukanisi zedijithali ezineziteshi ezimbili.Ukuze kube lula ukwakheka kwe-PCB, amashaneli aqondiswe ohlangothini olufanayo ku-ISO7220x nasezindaweni eziphambene ku-ISO7221x.Lawa madivayisi anebhafa yokufaka enengqondo nephumayo ehlukaniswe yi-TI's silicon-dioxide (SiO2) isithiyo sokuzihlukanisa, esihlinzeka ngokuhlukaniswa kwe-galvanic kufika ku-4000 VPKnge-VDE.Isetshenziswa ngokuhambisana nezinsiza zamandla ezihlukanisiwe, lezi zixhobo zivimba amandla kagesi aphezulu kanye nezizathu ezihlukanisayo, futhi zivimbela amaza omsindo ebhasini ledatha noma amanye amasekhethi ukuthi angangeni emhlabathini wendawo futhi aphazamise noma alimaze amasekhethi azwelayo.

Isingeniso

I-isolator yedijithali iyi-chip ohlelweni lwe-elekthronikhi lapho amasignali edijithali ne-analogi adluliselwa khona, ukuze abe nezici zokuzihlukanisa eziphakeme zokumelana nokuzuza ukuhlukaniswa phakathi kwesistimu ye-elekthronikhi nomsebenzisi.Abaklami bethula ukuhlukaniswa ukuze bahlangabezane nemithetho yokuphepha noma ukunciphisa umsindo weluphu yaphansi.Ukuhlukaniswa kwe-galvanic kuqinisekisa ukuthi ukudluliswa kwedatha akukhona ngokuxhumeka kukagesi noma izindlela zokuvuza, ngaleyo ndlela kugwema izingozi zokuphepha.Kodwa-ke, ukuzihlukanisa kubeka imikhawulo ekubambeni, ukusetshenziswa kwamandla, izindleko, nosayizi.Umgomo wezihlukanisi ezidijithali ukuhlangabezana nezidingo zokuphepha kuyilapho unciphisa imiphumela emibi.

Incazelo Yomkhiqizo

Isignali yokufaka kanambambili ifakwe esimweni, ihunyushwe kusignali ebhalansi, bese ihlukaniswa ngumgoqo wokuhlukanisa we-capacitive.Ngawo wonke umgoqo wokuhlukanisa, isiqhathanisi esihlukile sithola ulwazi loshintsho olunengqondo, bese sisetha noma sisethe kabusha i-flip-flop kanye nesekethe yokuphumayo ngokufanele.I-pulse yokubuyekeza ngezikhathi ezithile ithunyelwa kuwo wonke umgoqo ukuze kuqinisekiswe ileveli efanelekile ye-dc yokuphumayo.Uma le pulse ye-dc-refresh ingatholwa njalo ngo-4 µs, okokufaka kuthathwa njengokungashayelwa amandla noma akushayelwa ngokuqhubekayo, futhi isifunda se-failsafe sishayela okukhiphayo kusimo esiphakeme selogic.
Amandla amancane kanye nesikhathi esiwumphumela esingaguquki kunikeza ukusebenza okusheshayo ngamanani okusayina atholakalayo ukusuka ku-0 Mbps (DC) kuya ku-150 Mbps (Isilinganiso sokusayina somugqa inombolo yokuguqulwa kwamandla kagesi okwenziwa ngomzuzwana ovezwe kumayunithi we-bps).Amadivayisi we-A-option, B-option, kanye ne-C anemikhawulo yokufaka ye-TTL nesihlungi somsindo kokokufaka esivimbela ama-pulses esikhashana ukuthi adlulele ekuphumeni kwedivayisi.Amadivayisi enketho ye-M anemikhawulo yokufaka ye-CMOS VCC/2 futhi ayinaso isihlungi somsindo sokufakwayo nokubambezeleka okwengeziwe kokusabalalisa.
I-ISO7220x kanye ne-ISO7221x yomndeni wamadivayisi idinga ama-voltage amabili okunikezwayo angu-2.8 V (C-Grade), 3.3 V, 5 V, nanoma iyiphi inhlanganisela.Konke okokufaka kuyabekezelela i-5-V uma kunikezwa kusuka kokunikezwayo okungu-2.8-V noma okungu-3.3-V futhi konke okuphumayo kungu-4-mA CMOS.
I-ISO7220x kanye ne-ISO7221x yomndeni wamadivayisi iphawulelwe ukusebenza phezu kwezinga lokushisa le-ambient elingu -40°C kuya ku-+125°C.
