PMIC, yomwe imadziwikanso kuti IC kasamalidwe ka mphamvu, ndi dera lophatikizika lomwe limayang'anira magetsi pamakina akulu.
Pmics nthawi zambiri amagwiritsidwa ntchito pazida zoyendetsedwa ndi batri, monga mafoni am'manja kapena zosewerera zama media.Popeza zipangizo zoterezi nthawi zambiri zimakhala ndi mphamvu zoposa imodzi (monga batri ndi magetsi a USB), dongosololi limafuna mphamvu zambiri zamagetsi osiyanasiyana, ndipo kuwongolera ndi kutulutsa batri kuyenera kuyendetsedwa.Kukwaniritsa zofunikira zotere mwachikhalidwe kumatenga malo ambiri ndikuwonjezera nthawi yopangira zinthu, motero kutuluka kwa PMIC.
Ntchito yaikulu ya PMIC ndikuwongolera kayendetsedwe ka mphamvu ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Kuchokera kumagwero amagetsi angapo (mwachitsanzo, magwero amagetsi akunja, mabatire, magwero amagetsi a USB, ndi zina zotero), sankhani ndikugawa mphamvu kumadera osiyanasiyana adongosolo lalikulu kuti mugwiritse ntchito, monga kupereka magwero amagetsi angapo a ma voltages osiyanasiyana ndikuthandizira kulipiritsa mabatire amkati.Chifukwa makina omwe amagwiritsidwa ntchito nthawi zambiri amakhala ndi batri, amapangidwa ndi kutembenuka kwakukulu kuti achepetse kutaya mphamvu.
PMIC nthawi zambiri imakhala ndi ntchito zingapo.Ntchito izi zikuphatikizapo:
Dc-dc converter
Low pressure differential regulator (LDO)
Chaja cha batri
Kusankhidwa kwa magetsi
Dynamic voltage regulation
Yesetsani kutsatizana kwa kutsegula ndi kutseka kwa magetsi
Kuzindikira kwamagetsi amagetsi aliwonse
Kuzindikira kutentha
Ntchito zina
Chifukwa chofuna kulumikizana ndi makina akulu, mawonekedwe amasinthidwe omwe amafunikira kulumikizana ndi makina akulu nthawi zambiri amagwiritsa ntchito zolumikizira zingapo monga I²C kapena SPI.PMIC ina yokhala ndi ntchito zosavuta imalumikizana mwachindunji ndi GPIO ya MCU yokhala ndi ma sign odziyimira pawokha.
Ma PMICS ena amatha kulumikizidwa kumagetsi osungira kuti agwiritse ntchito nthawi yeniyeni, ndipo ena azikhala ndi zizindikiro zosavuta zamphamvu, monga kugwiritsa ntchito ma lead kuti awonetse kuchuluka kwa batri ndi kutulutsa.
Ma PMICS ena adapangidwira banja linalake la MCUS, ndipo kampani yomwe imapanga MCUS yofananira idzakhala ndi firmware yopezeka kuti ithandizire ntchito ya PMIC.
