Inkcazo

Usapho lwemveliso ye-TPS22992x lunezixhobo ezimbini: TPS22992 kunye ne-TPS22992S.Isixhobo ngasinye sisitshixo somthwalo wetshaneli enye ene-8.7-mΩ powerMOSFET eyilelwe ukwandisa ukungasebenzisi koxinaniso lwamandla ukuya kuthi ga kwi-5.5 V kunye ne-6 A. Ixesha lokunyuka elilungelelanisiweyo libonelela bhetyebhetye lolandelelwano lwamandla kwaye linciphisa inrush yangoku kwimithwalo ephezulu yesakhono. vumela i-pin (ON), ekwaziyo ukudibanisa ngokuthe ngqo kunye neempawu ze-voltageGPIO eziphantsi (VIH = 0.8 V).Isixhobo se-TPS22992x sinesikhonkwane esikhethiweyo se-QOD sokukhupha imveliso ekhawulezileyo xa iswitshi icinyiwe, kwaye ixesha lokuwa (tFALL) lemveliso linokuhlengahlengiswa ngesixhasi sangaphandle.Kukho i-Power Good (PG) isignali kwisixhobo esibonisa xa i-MOSFET engundoqo ivulwe ngokupheleleyo, enokuthi isetyenziswe ukunika amandla ukuthotywa kwe-downstream.Zombini izixhobo ze-TPS22992x ziza kunye ne-thermalshutdown ukuqinisekisa ukhuseleko kwiindawo eziphakamileyo zokushisa.Isixhobo se-TPS22992S kwakhona sidibanisa ukhuseleko lwangoku, ukuthintela umonakalo kwisixhobo ukuba imveliso ifinyeziwe emhlabeni ngexesha lokusebenza okanye ekuqaleni. Kwizicelo zefom encinci, izixhobo ze-TPS22992x zifumaneka kwi-1.25 × 1.25mm, 0.4-mmpitch, i-8-pin WQFN iphakheji .Isixhobo se-TPS22992 sikwafumaneka kwi-1.5 × 1.25 mm, i-0.5-mm pitch, i-8-pinWQFN iphakheji apho i-pin pitch ebanzi ifunekayo.
Zombini ezi zixhobo ziphawulwe ukuba zisebenze kuluhlu lobushushu bomoya wasimahla obuphakathi kwe -40°C ukuya +125°C.
