Incazelo

Umndeni womkhiqizo we-TPS22992x uqukethe amadivayisi amabili: TPS22992 kanye ne-TPS22992S.Idivayisi ngayinye iyiswishi yokulayisha yesiteshi esisodwa enamandla angu-8.7-mΩMOSFET eklanyelwe ukukhulisa ukusetshenziswa kwamandla okuminyana kufikela ku-5.5 V no-6 A. Isikhathi esilungisekayo sokukhuphuka sinikeza ukuguquguquka kokulandelana kwamandla futhi sinciphise i-inrush current ukuze kulayishwe amandla aphezulu. vumela iphinikhodi (ON), ekwazi ukuxhumana ngokuqondile namasignali e-voltage ephansi yeGPIO (VIH = 0.8 V).Idivayisi ye-TPS22992x inephinikhodi ye-QOD yokuzikhethela ukuze ikhishwe ngokushesha lapho iswishi icishiwe, futhi isikhathi sokuwa (tFALL) sokukhipha singalungiswa ngesivikeli sangaphandle.Kukhona isignali ye-Power Good (PG) kudivayisi ebonisa ukuthi i-MOSFET eyinhloko ivulwe nini ngokugcwele, engasetshenziswa ukunika amandla ukulayisha okuya phansi.Zombili izisetshenziswa ze-TPS22992x ziza nokuvala kwe-thermal ukuze kuqinisekiswe ukuvikeleka ekushiseni okuphezulu kwemvelo.Idivayisi ye-TPS22992S iphinde ihlanganise ukuvikela kwamanje, ivikele umonakalo kudivayisi uma okukhiphayo kufinyezwa phansi ngesikhathi sokusebenza noma ukuqalisa. Ngezinhlelo zokusebenza ze-form factor encane, amadivayisi we-TPS22992x atholakala ngephakheji engu-1.25 × 1.25mm, 0.4-mmpitch, 8-pin WQFN .Idivayisi ye-TPS22992 iyatholakala futhi ngephimbo elingu-1.5 × 1.25 mm, 0.5-mm, 8-pinWQFN iphakeji lapho kudingeka khona iphimbo elibanzi.
Womabili la madivayisi aphawulelwe ukusebenza phezu kwezinga lokushisa lomoya wamahhala elisukela ku- -40°C kuya ku-+125°C.
