Whakaahuatanga
Ko te whanau hua TPS22992x e rua nga taputapu: TPS22992 me TPS22992S.Ko ia taputapu he whakakaera uta kotahi te hongere me te 8.7-mΩ powerMOSFET i hangaia hei whakanui ake i nga tono kiato mana ki te 5.5 V me te 6 A. Ko te waa whakatika ka taea te whakarite ngawari mo te raupapa hiko me te whakaiti i te tere o naianei mo nga uta punga nui. Whakahohehia te titi (ON), ka taea te hono tika ki nga tohu ngaohiko GPIO iti (VIH = 0.8 V).Kei roto i te taputapu TPS22992x he titi QOD mo te tuku tere i te wa ka whakawetohia te pana, ka taea te whakatika i te wa taka (tFALL) o te putanga ma te aukati o waho.He tohu Power Good (PG) kei runga i te taputapu e tohu ana i te wa e whakakaotia katoatia ana te MOSFET matua, ka taea te whakamahi kia taea ai te utaina ki raro. Ka tae mai nga taputapu TPS22992x e rua me te whakaweto waiariki hei tiaki i nga taiao teitei.Ka whakauru ano te taputapu TPS22992S i te whakamarumaru o naianei, hei aukati i te kino o te taputapu mena ka poto te putanga ki te whenua i te wa e mahi ana, i te tiimata ranei. .Kei te waatea ano te taputapu TPS22992 i roto i te 1.5 × 1.25 mm, 0.5-mm pitch, 8-pinWQFN mōkihi e hiahiatia ana he titi titi whanui.
Ko nga taputapu e rua kua tohuhia mo te mahi i runga i te awhe mahana-kore-kore o te -40°C ki te +125°C.
