PMIC, wanda kuma aka sani da ikon sarrafa wutar lantarki IC, ƙayyadaddun da'ira ce ta haɗaka wacce ke sarrafa kayan wuta don babban tsarin.
Ana amfani da pmics sau da yawa a cikin na'urori masu ƙarfin baturi, kamar wayoyin hannu ko na'urorin watsa labarai masu ɗaukar nauyi.Tunda irin waɗannan na'urori yawanci suna da wutar lantarki fiye da ɗaya (kamar baturi da wutar lantarki na USB), tsarin yana buƙatar samar da wutar lantarki da yawa na ƙarfin lantarki daban-daban, kuma dole ne a sarrafa caji da fitar da baturin.Haɗuwa da irin wannan buƙatu a cikin hanyar gargajiya zai mamaye sararin samaniya da yawa kuma yana haɓaka lokacin haɓaka samfuran, don haka fitowar PMIC.
Babban aikin PMIC shine don sarrafa wutar lantarki da kuma tafiyar matakai don biyan bukatun babban tsarin.Daga tushen wutar lantarki da yawa (misali, tushen wutar lantarki na gaskiya-yanzu na waje, batura, tushen wutar lantarki na USB, da sauransu), zaɓi kuma rarraba wutar zuwa sassa daban-daban na babban tsarin don amfani, kamar samar da hanyoyin samar da wutar lantarki da yawa na ƙarfin lantarki daban-daban da alhakin cajin batura na ciki.Saboda tsarin da ake amfani da su galibi ana amfani da batir, an tsara su tare da ingantaccen juzu'i don rage asarar wuta.
PMIC yawanci yana da ayyuka fiye da ɗaya.Waɗannan ayyuka sun haɗa da:
Dc-dc Converter
Matsakaicin bambancin matsa lamba (LDO)
Caja baturi
Zaɓin samar da wutar lantarki
Tsarin wutar lantarki mai ƙarfi
Sarrafa jerin buɗewar wutar lantarki da rufewa
Gano ƙarfin wutar lantarki na kowane wutar lantarki
Gano yanayin zafi
Sauran ayyuka
Saboda buƙatar daidaitawa tare da babban tsarin, mu'amalar sigina waɗanda ke buƙatar sadarwa tare da babban tsarin gabaɗaya suna amfani da mu'amalar jeri kamar I²C ko SPI.Wasu PMIC tare da ayyuka masu sauƙi za su haɗa kai tsaye zuwa GPIO na MCU tare da sigina masu zaman kansu.
Wasu PMICS za a iya haɗa su zuwa madaidaicin wutar lantarki don amfani da agogo na ainihi, kuma wasu za su sami alamun matsayi mai sauƙi, kamar amfani da ledoji don nuna cajin baturi da matsayi na fitarwa.
An tsara wasu PMICS don takamaiman iyali na MCUS, kuma kamfanin da ke haɓaka MCUS mai dacewa zai sami firmware don tallafawa aikin PMIC.
