Incazelo ye-TPS2052B
Amaswishi okusabalalisa amandla e-TPS20xxB ahloselwe ukusetshenziswa lapho imithwalo esindayo ye-capacitive namasekethe amafushane kungenzeka kuhlangatshezwane nayo.Lawa madivayisi ahlanganisa amaswishi kagesi we-MOSFET angu-70-mΩ N-channel kumasistimu okusabalalisa amandla adinga ukushintsha kwamandla amaningi kuphakheji eyodwa.Iswishi ngayinye ilawulwa okokufaka okusebenzayo okunengqondo.Ukushayela isango kunikezwa iphampu yokushaja yangaphakathi eklanyelwe ukulawula izikhathi ezikhuphukayo zokushintsha amandla kanye nezikhathi zokuwa ukuze kuncishiswe ukwanda kwamanje phakathi nokushintsha.Iphampu yokushaja idinga izingxenye zangaphandle futhi ivumela ukusebenza kusuka kokunikezwayo okuphansi njengo-2.7 V.
Uma umthwalo ophumayo udlula umkhawulo wamanje womkhawulo noma okufushane kukhona, idivayisi ikhawulela okukhiphayo kwamanje kuleveli ephephile ngokushintshela kumodi yamanje, idonsa okokukhiphayo kwe-overcurrent (OCx) okuphansi.Lapho ukulayishwa okusindayo okuqhubekayo kanye namasekhethi amafushane kukhulisa ukuchithwa kwamandla kuswishi, okubangela izinga lokushisa elihlanganayo, isekethe yokuvikela okushisayo ivala iswishi ukuze kuvinjelwe umonakalo.Ukuthola kabusha okuvela ekuvaleni kwe-thermal kuyazenzakalela uma idivayisi isipholile ngokwanele.Ukujikeleza kwangaphakathi kuqinisekisa ukuthi iswishi ihlala ivaliwe kuze kube yilapho i-voltage yokufaka evumelekile ikhona.Lokhu kushintsha kokusabalalisa amandla kuklanyelwe ukumisa umkhawulo wamanje ku-1 A (okuvamile).
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
