Banja lazinthu la TPS22992x lili ndi zida ziwiri: TPS22992 ndi TPS22992S.Chipangizo chilichonse chimakhala ndi chosinthira chamtundu umodzi chokhala ndi 8.7-mΩ powerMOSFET chopangidwira kukulitsa kusagwiritsa ntchito mphamvu kwamagetsi mpaka 5.5 V ndi 6 A. Nthawi yokhazikika yokhazikika imapereka kusinthasintha kwa kutsatizana kwa mphamvu ndikuchepetsa kuthamangitsidwa kwamagetsi kwakanthawi kochepa. yambitsani pini (ON), yomwe imatha kulumikizana mwachindunji ndi ma siginecha otsika amagetsiGPIO (VIH = 0.8 V).Chipangizo cha TPS22992x chili ndi pini ya QOD yosankha kuti itulutse mwachangu pomwe switch yazimitsidwa, ndipo nthawi yakugwa (tFALL) yotulutsa imatha kusinthidwa kudzera pa chopinga chakunja.Pali chizindikiro cha Power Good (PG) pa chipangizo chomwe chimasonyeza pamene MOSFET yaikulu yayatsidwa, yomwe ingagwiritsidwe ntchito kuti iwonetsetse kutsitsa.Zipangizo zonse za TPS22992x zimabwera ndi thermalshutdown kuti zitsimikizire kutetezedwa kumadera otentha kwambiri.Chipangizo cha TPS22992S chimaphatikizanso chitetezo chamakono, kuteteza kuwonongeka kwa chipangizocho ngati chiwongolerocho chikufupikitsidwa pansi panthawi yogwiritsira ntchito kapena poyambira. Pazogwiritsa ntchito mawonekedwe ang'onoang'ono, zida za TPS22992x zilipo mu 1.25 × 1.25mm, 0.4-mmpitch, phukusi la 8-pin WQFN .Chipangizo cha TPS22992 chikupezekanso mu 1.5 × 1.25 mm, 0.5-mm pitch, 8-pinWQFN phukusi pomwe pitch yotakata ikufunika.
Zida zonsezi zimagwira ntchito pa kutentha kwa mpweya wa -40 ° C mpaka +125 ° C.
