"M'chigawo cha Asia, momwe magalimoto a mawilo awiri ndiwo njira zoyendera za anthu ambiri, opanga magalimoto angapo akufuna masanjidwe osavuta oyendetsera nyali zoyenda kumbuyo ndi ma layisensi," atero a Rohm. "Komabe, mpaka pano, matenthedwe akapangidwe kazipangitsa kuti zikhale zovuta kwa oyendetsa ma LED kuti ma LED azitha kukwaniritsa zofunikira zonse kutengera kuchuluka kwa nyali, kuwala, chitetezo, ndi mtengo."
Atasanthula msika waukulu kwambiri wamagalimoto awiri, India, kampaniyo idasankha madalaivala anayi opanga 150mA / njira, ndikusintha kwamayendedwe onse, phukusi la 16pin.
Zotsatira zake zinali:
BD18337EFV-M yoyendetsa zingwe zazitali kwambiri za ma LED
BD18347EFV-M yoyendetsa zingwe zazitali kwambiri za ma LED.
Chip chimabwera ndi phukusi la mapiko a 5x6mm okhala ndi phukusi lotentha pansi pake.
Zowongolera zamakono zapakati zimaphatikizidwa ndipo, kuti muchepetse kutaya kwanyengo pakali pano, ndizotheka kuyika zotsutsana motsatana ndi LED iliyonse yamphamvu kuti igawane kutsika kwamagetsi pakati pa njanji yamagetsi ndi zingwe zazingwe. Komanso, Rohm yapereka pini yapadera (VinRes) ndi kayendedwe ka mkati kolola kuti ma resistor onsewa aphatikizidwe kukhala amodzi a njanji, kuwerengera kwa LED komanso zamakono.
Kuzindikira cholakwika ndi chitetezo kumaphatikizapo: Kutseguka kwa LED, kufupikitsa, kutentha kwambiri komanso kutentha. Nthawi zambiri chip ichi chikamagwiritsidwa ntchito kuwongolera kuyatsa pagalimoto yomweyo, basi yokhayokha pakati pa tchipisi imalola kuti zolakwikazo zigawidwe ndikuchitapo kanthu.
"Ngati nyali yakumbuyo yalephera kuyatsa, opanga amatha kusankha kuzimitsa nyali zonse kapena chingwe chomwe chalephera," adatero Rohm. "Popeza miyezo yachitetezo cha nyali zamagudumu awiri okhala ndi ziphaso zikachitika mosayembekezereka zimasiyanasiyana mmaiko osiyanasiyana, nkhani zaposachedwa izi zithandizira kutsatira malamulo amchigawo chimodzi."
Mapulogalamu akuyembekezeredwa mu: nyali zakumbuyo (kuyimitsa / mchira), nyali za chifunga, ma siginolo osintha, nyali zama nambala ndi magetsi oyenda masana.
