PMIC, eo hape e tsejoang e le IC ea tsamaiso ea matla, ke potoloho e itseng e kopanetsoeng e laolang lisebelisoa tsa motlakase bakeng sa tsamaiso e kholo.
Hangata li-Pmics li sebelisoa lisebelisoa tse tsamaisoang ke betri, joalo ka mehala ea cellular kapa libapali tsa media tse nkehang.Kaha hangata lisebelisoa tse joalo li na le matla a fetang a le mong (joalo ka betri le motlakase oa USB), tsamaiso e hloka matla a mangata a matla a fapaneng, 'me tefo le ho tsoa ha betri li tlameha ho laoloa.Ho finyella tlhokahalo e joalo ka mokhoa oa setso ho tla nka sebaka se ngata le ho eketsa nako ea tlhahiso ea lihlahisoa, kahoo ho hlaha ha PMIC.
Mosebetsi o ka sehloohong oa PMIC ke ho laola phallo ea matla le tataiso ea phallo ho finyella litlhoko tsa tsamaiso e kholo.Ho tsoa mehloling e mengata ea matla (mohlala, mehloli ea matla ea 'nete ea hona joale, libeteri, mehloli ea matla a USB, joalo-joalo), khetha le ho abela matla likarolong tse fapaneng tsa sistimi ea mantlha hore e sebelisoe, joalo ka ho fana ka mehloli e mengata ea matla a matla a fapaneng le boikarabello ho tjhaja dibetri tsa ka hare.Hobane litsamaiso tse sebelisoang hangata li tsamaisoa ke betri, li entsoe ka ts'ebetso e phahameng ea phetoho ho fokotsa tahlehelo ea matla.
PMIC hangata e na le mesebetsi e fetang e le 'ngoe.Mesebetsi ena e kenyeletsa:
Dc-dc converter
Taolo e tlase ea khatello e tlase (LDO)
Sesebelisoa sa betri
Khetho ea phepelo ea motlakase
Taolo ea matla a matla
Laola tatellano ea ho bula le ho koala phepelo ea motlakase
Ho lemoha ha motlakase oa motlakase o mong le o mong
Ho lemoha mocheso
Mesebetsi e meng
Ka lebaka la tlhoko ea ho hokahana le sistimi e kholo, likhokahano tsa matšoao tse hlokang ho hokahana le sistimi e kholo hangata li sebelisa li-interfaces tse kang I²C kapa SPI.PMIC e 'ngoe e nang le mesebetsi e bonolo e tla hokela ka kotloloho ho GPIO ea MCU ka matšoao a ikemetseng.
Li-PMICS tse ling li ka hokeloa phepelong ea motlakase bakeng sa tšebeliso ea oache ea nako ea nnete, 'me tse ling li tla ba le matšoao a bonolo a boemo ba matla, joalo ka ho sebelisa li-leds ho bonts'a ho tjhaja betri le boemo ba ho tjhaja.
Li-PMICS tse ling li etselitsoe lelapa le itseng la MCUS, 'me khamphani e hlahisang MCUS e lumellanang e tla ba le firmware e fumanehang ho tšehetsa mosebetsi oa PMIC.
