Inkcazelo ye-TPS40200
I-TPS40200 isilawuli esiguquguqukayo, esingahambelaniyo nesinomqhubi owakhelwe ngaphakathi we-200-mA yee-P-channel FETs.Isekethe isebenza ngamagalelo ukuya kuthi ga kwi-52 V kunye nesici sokugcina amandla esicima umsinga womqhubi yakuba i-FET yangaphandle ilayitiwe ngokupheleleyo.Olu phawu lwandisa ukuguquguquka kwesixhobo, luvumela ukuba lusebenze ngegalelo lombane ukuya kuthi ga kwi-52 V ngaphandle kokuchitha amandla amaninzi.Isekethe isebenza ngengxelo yemowudi yombane kwaye inembuyekezo yegalelo lamandla okuhambisa phambili ephendula ngoko nangoko kutshintsho lwegalelo lombane.Isalathiso esidityanisiweyo se-700-mV silungiswe ukuya kwi-2%, sibonelela ngeendlela zokulawula ngokuchanekileyo amandla ombane aphantsi.I-TPS40200 ifumaneka kwi-8-pin ye-SOIC kunye ne-8-pin ye-VSON iphakheji kwaye ixhasa ezininzi iimpawu zabalawuli abanzima ngakumbi.Ukuphindaphindwa kwewotshi, isiqalo esithambileyo, kunye nemida edlulayo nganye icwangciswe ngokulula yinto enye, yangaphandle.Inxalenye ine-undervoltage lockout, kwaye inokulungelelaniswa ngokulula kwabanye abalawuli okanye iwotshi yenkqubo ukwanelisa ulandelelwano kunye / okanye iimfuno zokunciphisa ingxolo.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
