"Esifundeni sase-Asia, lapho izimoto ezinamasondo ama-2 kuyizindlela zokuhamba eziningi kwabaningi, abakhiqizi bezimoto abaningi befuna ukulungiswa kwesekethe okulula ukushayela amalambu ajwayelekile angemuva nangamalayisense," kusho uRohm. "Kodwa-ke, kuze kube manje izinkinga ezishisayo zokwenza kube nzima kubashayeli be-LED ukuthi ama-LED anika amandla ukuhlangabezana nazo zonke izidingo ezahlukahlukene ngokwesibani, ukukhanya, ukuphepha nezindleko."
Ngemuva kokuhlaziya imakethe enkulu kunazo zonke yezimoto ezinamasondo amabili, eNdiya, inkampani ithathe isinqumo ngabashayeli beziteshi ezine abakhiqiza i-150mA / isiteshi, ngokulungiswa kwamanje kwesiteshi ngasinye, kwiphakethe le-16pin.
Umphumela waba:
I-BD18337EFV-M yokushayela izintambo zochungechunge ezintathu eziphakeme zama-LED
I-BD18347EFV-M yokushayela izintambo zochungechunge ezimbili eziphakeme zama-LED.
I-chip ifika iphakethe le-5x6mm gull-wing elinephedi elishisayo ngaphansi.
Izilawuli zamanje ezingaphakathi zangaphakathi zifakiwe futhi, ukunciphisa ukushabalalisa ukushisa njengamanje, kungenzeka ukubeka i-resistor ochungechungeni nge-LED ngayinye eqinile ukusiza ukwaba ukwehla kwamandla kagesi phakathi kwezitimela zamandla nezintambo zezintambo. Futhi, i-Rohm inikeze iphini elihlukile (i-VinRes) kanye nesekethe yokulawula kwangaphakathi ukuvumela wonke lawa ma-resistors ukuthi ahlanganiswe abe munye ngenhlanganisela ethile yesitimela, isibalo se-LED nesamanje.
Ukutholwa kwephutha nokuvikelwa kufaka phakathi: i-LED evulekile, isekhethi elifushane, i-over-voltage kanye nokushisa. Lapho kusetshenziswa izimo eziningi zale chip ukulawula ukukhanya emotweni efanayo, ibhasi likaphini elilodwa phakathi kwamachips livumela isimo sephutha ukuthi sabiwe futhi kusetshenzwe ngaso.
"Uma isibani sangemuva sehluleka ukukhanyisa, abasiki bengqephu bangakhetha ukucisha zonke izibani noma kuphela uchungechunge oluhlulekile," kusho uRohm. "Ngenxa yokuthi amazinga okuphepha kwamalambu amapuleti amalayisense anamasondo amabili uma kwenzeka kuba nokungajwayelekile kuyahluka ngokwamazwe, lolu chungechunge lwakamuva lwenza ukuthi kulandelwe imithetho yezifunda ezinesimiso esisodwa."
Izicelo kulindeleke ukuthi zibe ngamalambu angemuva (isitobhi / umsila), amalambu enkungu, izinkomba zamasignali okujika, amalambu enombolo yamalambu namalambu asebenza emini.
