Ibikoresho by'inyongera

PMIC, izwi kandi nk'icungamutungo rya IC, ni umuzenguruko wihariye uhuza ibikoresho bitanga amashanyarazi kuri sisitemu nkuru.

Pmics ikoreshwa kenshi mubikoresho bikoreshwa na bateri, nka terefone igendanwa cyangwa abakinisha ibitangazamakuru byoroshye.Kubera ko ibyo bikoresho mubisanzwe bifite amashanyarazi arenze imwe (nka bateri na USB itanga amashanyarazi), sisitemu isaba amashanyarazi menshi yumuriro utandukanye, kandi kwishyurwa no gusohora bateri bigomba kugenzurwa.Guhuza ibyo bisabwa muburyo gakondo bizatwara umwanya munini kandi byongere igihe cyiterambere ryibicuruzwa, bityo PMIC igaragara.

Igikorwa nyamukuru cya PMIC ni ukugenzura ingufu zitemba nicyerekezo cyoguhuza ibikenewe muri sisitemu nkuru.Uhereye ku masoko menshi yingufu (urugero, amasoko yukuri-agezweho yimbaraga, bateri, USB amashanyarazi, nibindi), hitamo kandi ukwirakwize ingufu mubice bitandukanye bya sisitemu nkuru yo gukoresha, nko gutanga amasoko menshi yingufu za voltage zitandukanye kandi ushinzwe kwishyuza bateri y'imbere.Kuberako sisitemu zikoreshwa ahanini zikoreshwa na bateri, zakozwe hamwe nuburyo bwiza bwo guhindura kugirango zigabanye gutakaza ingufu.

Ubusanzwe PMIC ifite imikorere irenze imwe.Iyi mirimo irimo:

Dc-dc

Umuvuduko muke utandukanya ibintu (LDO)

Amashanyarazi

Guhitamo amashanyarazi

Amashanyarazi ya Dynamic

Kugenzura urukurikirane rw'amashanyarazi afungura no gufunga

Kugaragaza ingufu za buri mashanyarazi

Kumenya ubushyuhe

Indi mirimo

Bitewe no gukenera guhuza na sisitemu nkuru, ibimenyetso byerekana ibimenyetso bigomba kuvugana na sisitemu nkuru muri rusange ukoresha urukurikirane rwimikorere nka I²C cyangwa SPI.PMIC imwe ifite imikorere yoroshye izahuza na GPIO ya MCU nibimenyetso byigenga.

PMICS zimwe zirashobora guhuzwa no kugarura amashanyarazi kugirango akoreshe amasaha nyayo, kandi bamwe bazagira ibipimo byoroheje byerekana imbaraga, nko gukoresha ingeri kugirango berekane umuriro wa batiri ndetse nuburyo bwo gusohora.

PMICS zimwe zagenewe umuryango wihariye wa MCUS, kandi isosiyete itunganya MCUS ijyanye nayo izaba ifite porogaramu zihari zo gushyigikira umurimo wa PMIC.
