PMIC, inozivikanwawo sesimba manejimendi IC, idunhu rakasanganiswa rinobata magetsi eiyo main system.
Pmics inowanzoshandiswa mumidziyo ine bhatiri, senge mbozhanhare kana inotakurika midhiya inoridza.Sezvo zvigadzirwa zvakadaro zvinowanzova neanopfuura simba rimwe chete (senge bhatiri uye USB magetsi ekupa), sisitimu inoda akawanda magetsi emagetsi akasiyana, uye kubhadharisa uye kubuda kwebhatiri kunofanirwa kudzorwa.Kusangana nezvinodiwa zvakadaro nenzira yechinyakare kunotora nzvimbo yakawanda uye kuwedzera nguva yekuvandudza chigadzirwa, nekudaro kubuda kwePMIC.
Basa guru rePMIC ndere kudzora kuyerera kwesimba uye mafambiro ekuyerera kuti asangane nezvinodiwa zveiyo main system.Kubva kune akawanda masosi emagetsi (semuenzaniso, ekunze echokwadi-azvino masosi emagetsi, mabhatiri, USB magetsi masosi, nezvimwewo), sarudza uye govera simba kuzvikamu zvakasiyana zveiyo main system kuti ishandiswe, sekupa akawanda masimba emagetsi akasiyana uye anokonzeresa kuchaja mabhatiri emukati.Nekuda kwekuti masisitimu anoshandiswa anonyanya kufambiswa nebhatiri, akagadzirwa ane yakanyanya kutendeuka kunyatso kudzikisa kurasikirwa kwemagetsi.
PMIC inowanzova neanopfuura basa rimwechete.Aya mabasa anosanganisira:
Dc-dc converter
Low pressure differential regulator (LDO)
Battery charger
Kusarudzwa kwemagetsi
Dynamic voltage regulation
Dzora kutevedzana kwemagetsi ekuvhura nekuvhara
Voltage yekuona yega yega magetsi
Kuonekwa kwekupisa
Mamwe mabasa
Nekuda kwekuda kurongeka neiyo huru sisitimu, masaini machinjiro anoda kutaurirana neiyo huru sisitimu anowanzo shandisa akatevedzana mainterface akadai seI²C kana SPI.Imwe PMIC ine mabasa akareruka anozobatana zvakananga kuGPIO yeMCU nemasaini akazvimirira.
Mamwe maPMICS anogona kubatanidzwa kune backup magetsi ekushandisa chaiyo-nguva yewachi, uye mamwe achave akareruka emagetsi mamiriro ezviratidzo, sekushandisa leds kuratidza bhatiri yekuchaja uye yekuburitsa mamiriro.
Mamwe maPMICS akagadzirirwa imwe mhuri yeMCUS, uye kambani inogadzira inoenderana MCUS ichave nefirmware iripo yekutsigira basa rePMIC.
