Uqwalaselo lwe-UL olongezelelweyo lwe-TPS2042B kunye ne-TPS2052B kuqwalaselo lweGanged
Inkcazelo ye-TPS2052B
Iiswitshi zokusasazwa kwamandla e-TPS20xxB zenzelwe usetyenziso apho imithwalo enzima ye-capacitive kunye neesekethe ezimfutshane kunokuqubisana nazo.Ezi zixhobo ziquka i-70-mΩ i-N-channel ye-MOSFET yokutshintsha amandla kwiinkqubo zokusasazwa kwamandla ezifuna ukutshintshwa kwamandla amaninzi kwiphakheji enye.Iswitshi nganye ilawulwa yi-logic enableinput.Isango lokuqhuba isango linikezelwa yimpompo yentlawulo yangaphakathi eyenzelwe ukulawula ukunyuka kwamandla okutshintsha kunye namaxesha okuwa ukunciphisa ukunyuka kwangoku ngexesha lokutshintsha.Impompo yokutshaja ifuna amacandelo angaphandle kwaye ivumela ukusebenza ukusuka kunikezelo olusezantsi njenge-2.7 V.
Xa umthwalo wemveliso udlula umda wangoku okanye omfutshane okhoyo, isixhobo sinqanda imveliso yangoku ukuya kwinqanaba elikhuselekileyo ngokutshintshela kwimowudi yangoku, ukutsala i-overcurrent (OCx) i-logic output low.Xa imithwalo enzima eqhubekayo kunye neesekethe ezimfutshane zandisa ukuchithwa kwamandla kwi-switch, ebangela i-torise ye-junction yobushushu, isiphaluka sokukhusela i-thermal sivala iswitshi ukukhusela umonakalo.Ukubuyisela kwakhona ukusuka ku-thermalshutdown kuyazenzekela xa isixhobo siphole ngokwaneleyo.Umjikelo wangaphakathi uqinisekisa ukuba iswitshi ihlala icinyiwe de kubekho amandla ombane asebenzayo.Olu tshintsho lokusasazwa kwamandla luyilelwe ukuseta umda wangoku kwi-1 A (eqhelekileyo).
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
