PMIC, oo sidoo kale loo yaqaan maamulka korantada IC, waa wareeg gaar ah oo isku dhafan oo maamusha sahayda korontada ee nidaamka ugu muhiimsan.
Pmics waxaa inta badan loo adeegsadaa aaladaha ku shaqeeya baytari, sida taleefoonnada gacanta ama cayaartoyda warbaahinta la qaadan karo.Maadaama aaladaha noocaan ah ay badanaa leeyihiin wax ka badan hal sahay (sida batteriga iyo korontada USB), nidaamku wuxuu u baahan yahay sahay koronto oo badan oo danab kala duwan ah, dallacaadda iyo soo saarista batteriga waa in la xakameeyaa.In la daboolo baahida noocaas ah ee habka dhaqameedku waxay qabsan doontaa meelo badan waxayna kordhin doontaa wakhtiga horumarinta alaabta, sidaas awgeed soo bixitaanka PMIC.
Shaqada ugu weyn ee PMIC waa in la xakameeyo socodka korantada iyo jihada qulqulka si loo daboolo baahiyaha nidaamka ugu muhiimsan.Laga soo bilaabo ilo koronto oo badan (tusaale, ilaha korantada ee dhabta ah ee dibadda, baytariyada, ilaha tamarta USB, iwm.), dooro oo u qaybi awooda qaybaha kala duwan ee nidaamka ugu muhiimsan ee isticmaalka, sida bixinta ilo badan oo koronto oo kala duwan oo mas'uul ka ah ku dallaca baytariyada gudaha.Sababtoo ah nidaamyada la isticmaalo ayaa inta badan ku shaqeeya baytari, waxaa loo qaabeeyey waxtarka beddelka sare si loo yareeyo khasaaraha korontada.
PMIC badanaa waxay leedahay in ka badan hal shaqo.Hawlahan waxaa ka mid ah:
Beddelaha Dc-dc
Xakamaynta kala duwanaanshaha cadaadiska hooseeya (LDO)
Dabaylaha baytari
Doorashada sahayda korontada
Nidaaminta danab firfircoon
Xakamee isku xigxiga furitaanka iyo xidhitaanka sahayda korontada
Ogaanshaha korantada ee sahay koronto kasta
Ogaanshaha heerkulka
Hawlaha kale
Baahida loo qabo in la isku xidho nidaamka ugu muhiimsan awgeed, is-dhex-galayaasha calaamadaha ee u baahan in lala xidhiidho nidaamka guud guud ahaan waxay adeegsadaan isdhexgal taxane ah sida I²C ama SPI.Qaar ka mid ah PMIC oo leh hawlo fudud ayaa si toos ah ugu xidhi doona GPIO ee MCU oo leh calaamado madax-banaan.
Qaar ka mid ah PMICS waxaa lagu xiri karaa sahay koronto ah oo loogu talagalay isticmaalka waqtiga-dhabta ah, qaarna waxay yeelan doonaan tilmaameyaal heerka korantada oo fudud, sida isticmaalka ledhka si ay u muujiyaan ku dallacaadda batteriga iyo heerka soo daynta.
Qaar ka mid ah PMICS waxaa loogu talagalay qoys gaar ah oo MCUS ah, iyo shirkadda soo saarta MCUS u dhiganta waxay lahaan doontaa firmware diyaar u ah inuu taageero shaqada PMIC.
