I-PMIC, eyaziwa ngokuba yi-IC yolawulo lwamandla, yisekethe ethile edibeneyo elawula ukunikezelwa kwamandla kwenkqubo engundoqo.
IiPmics zihlala zisetyenziswa kwizixhobo ezisebenza ngebhetri, njengeefowuni eziphathwayo okanye iisidlali zemidiya eziphathwayo.Ekubeni ezo zixhobo zihlala zinamandla angaphezu kwesinye (njengebhetri kunye nombane we-USB), inkqubo idinga amandla amaninzi ombane ohlukeneyo, kwaye ukuhlawulwa kunye nokukhutshwa kwebhetri kufuneka kulawulwe.Ukuhlangabezana nemfuno enjalo ngendlela yendabuko kuya kuthatha indawo eninzi kwaye kwandise ixesha lokuphuhlisa imveliso, ngoko ke ukuvela kwe-PMIC.
Umsebenzi ophambili we-PMIC kukulawula ukuhamba kwamandla kunye nesikhokelo sokuhamba ukuhlangabezana neemfuno zenkqubo ephambili.Ukusuka kwimithombo yamandla emininzi (umzekelo, imithombo yamandla yangaphandle eyinyani-yangoku, iibhetri, imithombo yamandla e-USB, njl.njl.), khetha kwaye usasaze amandla kwiindawo ezahlukeneyo zenkqubo engundoqo ukuze isetyenziswe, njengokubonelela ngemithombo yombane emininzi eyahlukeneyo yombane kunye noxanduva ukutshaja iibhetri zangaphakathi.Kuba iisistim ezisetyenziswayo ubukhulu becala zinebhetri, ziyilwe ngoguqulo olusulungekileyo lokunciphisa ilahleko yamandla.
I-PMIC idla ngokuba nomsebenzi ongaphezulu kwesinye.Le misebenzi ibandakanya:
Isiguquli seDc-dc
Ulawulo loxinzelelo olusezantsi (LDO)
Itshaja yebhetri
Ukukhetha unikezelo lwamandla
Ukulawulwa kwamandla ombane anamandla
Lawula ulandelelwano lokuvula nokuvalwa konikezelo lwamandla
Ukufunyanwa kwe-voltage yobonelelo lwamandla ngamnye
Ukufunyanwa kobushushu
Eminye imisebenzi
Ngenxa yesidingo sokulungelelaniswa nenkqubo ephambili, ujongano lomqondiso olufuna ukunxibelelana nenkqubo ephambili ngokuqhelekileyo lusebenzisa ujongano olufana ne-I²C okanye iSPI.Enye i-PMIC enemisebenzi elula iya kudibanisa ngqo kwi-GPIO ye-MCU eneempawu ezizimeleyo.
Ezinye i-PMICS zinokudityaniswa kunikezelo lwamandla olugcinayo losetyenziso lwewotshi yexesha langempela, kwaye ezinye ziya kuba nezikhombisi zesimo samandla esilula, njengokusebenzisa iiledi ukubonisa ukutshaja kwebhetri kunye nesimo sokukhupha.
Ezinye ii-PMICS ziyilelwe usapho oluthile lwe-MCUS, kwaye inkampani ephuhlisa i-MCUS ehambelanayo iya kuba ne-firmware ekhoyo ukuxhasa umsebenzi we-PMIC.
