Ungacela iingxelo zovavanyo, idatha ye-voltage, kunye nezikhokelo. Le nkxaso ikunceda ukusombulula iingxaki ze-voltage kunye nokutshintsha ngokukhawuleza. Ikwakunceda ugcine inkqubo yakho yolawulo lombane ikhuselekile kwaye ithembekile.
Unceda ekwenzeni iimoto zikhuseleke kwaye zithembeke. Khetha ii-IC zombane kunye nee-PMIC ezilandela imithetho enzima. Mamela oko kuthethwa ngumvelisi kwaye usebenzise amanyathelo oyilo lwe-PCB alungileyo. Jonga imithetho emitsha kunye nohlaziyo rhoqo. Oku kukunceda uhlale usesikhathini kwaye wenze umsebenzi ongcono kwishishini leemoto.
FAQ
Yintoni eyona nto ibalulekileyo xa ukhetha i-IC yombane kwizicelo zeemoto?
Kufuneka uqinisekise ukuba i-voltage kunye nomsinga zihambelana nenkqubo yakho. Oku kugcina uyilo lwakho lukhuselekile kwaye lunceda ukuba lusebenze kakuhle ezimotweni.
Uzikhusela njani ii-IC zombane kubushushu kwiindawo zeemoto?
Ungasebenzisa izinto ezifana nezitshisi zobushushu kunye nokubeka iindawo ngobuchule. Ezi ngcinga zinceda ii-IC zakho zihlale zipholile kwaye zihlale ixesha elide.
Kutheni ufuna izihluzi ze-EMI kuyilo lombane weemoto?
Izihluzi ze-EMI zithintela ingxolo yombane ukuba ingasasazeki. Zinceda izinzwa, iirediyo, kunye neekhamera zisebenze kanye emotweni yakho.
Ujonga njani ukuba i-IC yombane iyahlangabezana nemigangatho yeemoto?
Kuya kufuneka ujonge izinto ezinje I-AEC-Q100 kunye ne-ISO 26262Oku kubonisa ukuba ii-IC zakho ziyakwazi ukumelana neemeko zemoto enzima.
Yintoni omele uyenze ukuba i-IC yakho yombane ayisebenzi kakuhle emotweni?
Ungajonga i-voltage, ujonge iingcingo, kwaye usebenzise izixhobo zovavanyo. La manyathelo akunceda ufumane kwaye ulungise iingxaki ngokukhawuleza.
