I-STGAP2HS Ihlukaniswe ngocingo olu-4 Umshayeli weSango Elilodwa

Umshayeli wesango elilodwa le-STMicroelectronics unikeza ukuhlukaniswa kwe-galvanic phakathi kwesiteshi sokushayela esangweni kanye nokulawulwa kwamandla aphansi

STMicroelectronics STGAP2HS Galvanically Isolated 4 A Single Gate Driver I-STMicroelectronics 'STGAP2HS umshayeli wesango elilodwa ohlinzeka ngokuhlukaniswa kwe-galvanic phakathi kwesiteshi sokushayela esangweni kanye nokulawulwa kwamandla aphansi nokujikeleza kwesixhumi. Umshayeli wesango ubonakala ngamandla we-4 A kanye nokukhishwa kwesitimela kuya esitimeleni, okwenza le divayisi futhi ilungele ukusetshenziswa kwaphakathi nendawo namandla amakhulu njengokuguqulwa kwamandla kanye nabaguquli bezimoto emisebenzini yezimboni. Idivayisi itholakala ngokulungiselela okubili okuhlukile. Ukucushwa ngezikhonkwane zokukhipha ezihlukanisiwe kuvumela abasebenzisi ukuthi basebenzise ngokuzimela ukuvula nokuvula ngokusebenzisa izivikeli zesango ezinikele. Ukucushwa okuqukethe iphini elilodwa lokukhipha nomsebenzi weMiller CLAMP kuvimbela ama-spikes esango ngesikhathi sokuhamba okusheshayo kuma-topologies wesigamu sebhuloho. Kokubili ukucushwa kunikeza ukuguquguquka okuphezulu kanye nomthethosivivinywa wokwehliswa kwezinto zezinto zangaphandle. Idivayisi ihlanganisa i-UVLO nemisebenzi yokuvikela ukuvala ezishisayo ukwenza lula ukwakheka kwezinhlelo ezinokwethenjelwa kakhulu. Izikhonkwane zokufaka ezimbili zivumela ukukhethwa kokulawulwa kwesiginali kwe-polarity kanye nokuqaliswa kokuvikelwa kokuxhumeka kwe-HW ukugwema ukwenziwa kokuwela uma kwenzeka ukungasebenzi kahle kwesilawuli. Okokufaka ekubambezelweni kokukhishwa kokusakazwa kungaphansi kwama-75 ns, aletha ukunemba okuphezulu kokulawula kwe-PWM. Imodi yokulinda iyatholakala ukunciphisa ukusetshenziswa kwamandla okungenzi lutho.
