Ibisobanuro

Umuryango wibicuruzwa bya TPS22992x ugizwe na twodevices: TPS22992 na TPS22992S.Buri gikoresho isa numuyoboro umwe wumutwaro uhinduranya hamwe na 8.7-mΩ powerMOSFET yagenewe kugirango hongerwe ingufu zingana zingana na 5.5 V na 6 A. Igihe cyagenwe gitanga uburyo bworoshye bwo gukurikiranya ingufu kandi bikagabanya inrush yumuvuduko mwinshi. gushoboza pin (ON), ishoboye guhuza neza na voltage nkeyaGPIO (VIH = 0.8 V).Igikoresho cya TPS22992x gifite QOD pin itabishaka kugirango isohoke byihuse iyo switch ihagaritswe, kandi igihe cyo kugwa (TFALL) cyibisohoka gishobora guhindurwa binyuze hanze.Hano hari ikimenyetso Cyiza (PG) kuri dedevice yerekana igihe MOSFET nkuru yuzuye yuzuye, ishobora gukoreshwa mugutwara ibintu byamanuka.Ibikoresho byombi bya TPS22992x bizana hamwe nubushyuhe bwo kurinda umutekano mukarere keza cyane.Igikoresho cya TPS22992S nacyo gihuza uburinzi burigihe, birinda kwangirika kwaduka niba ibisohoka bigufi kubutaka mugihe cyo gukorana cyangwa gutangira. Kubintu bito byerekana ibintu, TPS22992xdevices iraboneka muri 1.25 × 1.25mm, 0.4-mmpitch, 8-pin WQFN .Igikoresho cya TPS22992 isalso kiboneka muri mm 1.5 × 1,25 mm, ikibanza cya 0.5-mm, 8-pinWQFN aho hakenewe ikibuga kinini.
Ibikoresho byombi birangwa no gukora hejuru yubushyuhe bwikirere bwa dogere 40 ° C kugeza kuri + 125 ° C.
