Incazelo ye-ULN2003A
Amadivayisi e-ULx200xA ane-voltage ephezulu, ama-arrays amanje aphezulu e-Darlington transistor.Ngayinye iqukethe amapheya ayisikhombisa e-NPN Darlington afaka ukuphuma kwe-high-voltage nama-common-cathode clamp diode okushintsha imithwalo ye-inductive.
Isilinganiso samanje se-Darlington pair singu-500 mA.I-Darlington pairs ingafaniswa ukuze ikwazi ukusebenza manje.Izinhlelo zokusebenza zifaka izishayeli ezidluliswayo, izishayeli zesando, izishayeli zamalambu, izishayeli ezibonisayo (i-LED nokukhishwa kwegesi), izishayeli zelayini, namabhafa anengqondo.Ngezinguqulo ezingu-100-V (okunye ezingashintshwa) zemishini ye-ULx2003A, bonaI-SLRS023Idatha ye-SN75468 kanye ne-SN75469devices.
Idivayisi ye-ULN2002A yakhelwe ngokuqondile ukusetshenziswa namadivayisi we-PMOS angu-14-V kuya ku-25-V.Okokufaka ngakunye kwalolu cingo kune-Zener diode kanye ne-resistor ochungechungeni ukuze ulawule okokufaka kwamanje kumkhawulo ophephile.Amadivayisi e-ULx2003A ane-base resistor engu-2.7-kΩ yokupheya ngakunye kweDarlington ukuze asebenze ngokuqondile ne-TTL noma amadivayisi angu-5-V CMOS.
Amadivayisi e-ULx2004A ane-base resistor engu-10.5-kΩ ukuze avumele ukusebenza ngokuqondile kumadivayisi e-CMOS asebenzisa amandla okunikezwayo angu-6 V kuya ku-15 V. Okokufaka okudingekayo kwe-ULx2004Adevice kungaphansi kwamadivayisi e-ULx2003A, futhi i-voltage edingekayo ingaphansi lokho kudingwa yidivayisi ye-ULN2002A.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
