Iinketho zokwahlula imveliso zivumela ukulungiswa kwe-turnon kunye nemisinga yokujika
Ukuguqulela kunye nokungaguquguqukiyo kuqwalaselo lwegalelo
Nika amandla ngomda ohambelanayo we-TTL
Umthombo ophezulu we-2.5-A kunye ne-2.5-A okanye i-5-A i-sink peak drive currents kwi-18-V VDD
Uluhlu olubanzi lweVDD ukusuka kwi-10 V ukuya kwi-35 V
Faka kwaye uvule izikhonkwane ezikwaziyo ukuma ukuya kuthi ga kwi -5-V DC ngaphantsi komhlaba
Imveliso ibanjwe phantsi xa amagalelo adadayo okanye ngexesha le-VDD UVLO
Ulibaziseko olukhawulezayo lokusasaza (17-ns Eqhelekileyo)
Ukunyuka nokuwa ngokukhawuleza kwamaxesha
(15-ns kunye ne-7-ns eqhelekileyo kunye nomthwalo we-1800-pF)
Ukuvalwa kwe-Undervoltage (UVLO)
Isetyenziswa njengomqhubi wecala eliphakamileyo okanye elisezantsi (ukuba iyilwe ngocalucalulo olufanelekileyo kunye nophawu lodwa)
Iindleko eziphantsi, ukonga indawo 5-pin okanye 6-pin DBV (SOT-23) iinketho yepakethe
UCC27536 kunye UCC27537 pin-to-pin ehambelanayo TPS2828 kunye TPS2829
Ubushushu bokusebenza buphakathi -40°C ukuya ku-140°C
Inkcazelo ye-UCC27531
I-UCC2753x itshaneli enye, abaqhubi besango abanesantya esiphezulu banokuqhuba ngokufanelekileyo iMOSFET kunye nokutshintsha kwamandla eIGBT.Usebenzisa uyilo oluvumela umthombo ukuya kuthi ga kwi-2.5 A kunye ne-5-A isinki ngokusebenzisa i-drive ye-asymmetrical (iziphumo zokwahlula), kunye nokukwazi ukuxhasa ukucima okungalunganga, ukukwazi ukuqhuba umzila kaloliwe ukuya kuloliwe, ukulibaziseka okuncinci kakhulu kokusasaza. (i-17 ns eqhelekileyo), izixhobo ze-UCC2753x zizisombululo ezifanelekileyo ze-MOSFET kunye nokutshintsha kwamandla e-IGBT.Intsapho ye-UCC2753x yezixhobo nayo ikwazi ukunika amandla, igalelo elibini, kunye nokuguqula kunye nokusebenza kwegalelo elingaguqukiyo.I-splitouts kunye ne-asymmetrical drive eyomeleleyo yonyusa izixhobo zokugonyela ngokuchasene ne-parasitic Miller turn-oneeffect kwaye inokunceda ukunciphisa ukuthotywa komhlaba.
Ukushiya i-pin yokufaka ivuliwe kubamba imveliso yomqhubi ephantsi.Ukuziphatha okusengqiqweni komqhubi oboniswe kwidayagram yesicelo, idayagramu yexesha, kunye netheyibhile yenyaniso yegalelo kunye nesiphumo.
Ukujikeleza kwangaphakathi kwi-pin ye-VDD ibonelela ngomsebenzi wokutshixa ngaphandle kwe-voltage obambe imveliso ephantsi de i-voltage yobonelelo lwe-VDD ikuluhlu olusebenzayo.
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
