I-MPQ8633AGLE-Z
DESCRIPTION
I-MPQ8633A iyisiguquli sebuck esihlanganiswe ngokugcwele, esinemvamisa ephezulu, esivumelanayo.Inikeza isixazululo esihlangene kakhulu sokufinyelela okukhiphayo okungafika ku-12A phezu kohlu olubanzi lokuhlinzekwa kokufakwayo ngomthwalo omuhle kakhulu nokulawulwa komugqa.I-MPQ8633A isebenza ngokusebenza kahle okuphezulu phezu kwebanga lomthwalo wamanje ophumayo obanzi.
I-MPQ8633A yamukela imodi yokulawula enxeshezelwa ngaphakathi ehlala isikhathi eside (COT) enikeza impendulo yesikhashana esheshayo futhi yenza lula ukuqiniswa kweluphu.
Ifrikhwensi yokusebenza isethwe kalula ibe ngu-600kHz, 800kHz, noma 1000kHz ngokucushwa kwe-MODE, okuvumela ifrikhwensi ye-MPQ8633A ukuthi ihlale injalo kungakhathaliseki ukuthi ingakanani amandla okufaka/okukhiphayo.
Irempu yokuqala kagesi ephumayo ilawulwa isibali-sikhathi sangaphakathi esingu-1ms.Inganyuswa ngokwengeza i-capacitor ku-TRK/REF.Isignali yamandla e-open-drain good(i-PGOOD) ibonisa ukuthi okukhiphayo kungaphakathi kwebanga le-voltage elilinganiselwe.I-PGOOD iboshelwe cishe ku-0.7V nge-voltage yokudonsa yangaphandle lapho okokufaka kwehluleka ukunika amandla i-MPQ8633A.
Izici zokuvikela ezihlanganiswe ngokugcwele zifaka ukuvikelwa kwe-overcurrent (OCP), ukuvikelwa kwe-over-voltage (OVP), ukuvikelwa okungaphansi kwe-voltage (UVP), nokuvikelwa kwe-overtemperature (OTP).
I-MPQ8633A idinga inani elincane lezingxenye ezitholakala kalula, ezijwayelekile, zangaphandle futhi itholakala kuphakheji ye-QFN 3mm x 4mm.
