LP87702DRHBRQ1 Ubwiza Bwiza Bwiza & Umwimerere IC Yinjijwe Kumuzunguruko Ibikoresho bya elegitoronike Mububiko bwerekanwe

ibisobanuro bigufi:

LP87702-Q1 ifasha kuzuza ibisabwa byo gucunga ingufu za platform zigezweho, cyane cyane muri radar yimodoka na kamera hamwe na radar yinganda zikoreshwa.Igikoresho kirimo intambwe ebyiri zimanuka DC / DC zihindura, hamwe na 5-V izamura imbaraga kugirango ishyigikire porogaramu zikomeye z'umutekano.Igikoresho gihuza ibyinjira bibiri byo kugenzura ibikoresho byoherejwe hanze hamwe nidirishya ryirinda.
Igikorwa cyikora cya PWM / PFM (uburyo bwa AUTO) gitanga umusaruro mwinshi hejuru yumusaruro mugari ugenda uhindura amafaranga.LP87702-Q1 ikoresha amashanyarazi ya kure kugirango yishyure IR igabanuka hagati yumusaruro uhinduka hamwe nu ngingo-y-umutwaro, bityo bikazamura ukuri kwa voltage isohoka.

PMIC?

I. PMIC ni iki
PMIC ni impfunyapfunyo yo gucunga ingufu IC, ikintu nyamukuru nicyiciro cyo hejuru cyo kwishyira hamwe, gakondo gakondo itanga amashanyarazi menshi muri chip kugirango ibintu byinshi bikoresha amashanyarazi bifite imikorere ihanitse, nubunini buto.PMICs ikoreshwa kenshi muri sisitemu ya CPU, nko gushyira hejuru-agasanduku gashushanyo, gushushanya amajwi yubwenge, gushushanya ibikoresho binini bigenzura inganda, nibindi.
PMIC imwe irashobora gucunga amashanyarazi menshi yo hanze, igashushanya sisitemu zitandukanye zisabwa kuri voltage ikwiye.Birashobora kandi gukoreshwa kubintu bitandukanye bitunganijwe, abagenzuzi ba sisitemu, hamwe na porogaramu zanyuma, bisaba gusa impinduka zijyanye no kwiyandikisha cyangwa porogaramu zikoreshwa, bitabaye ngombwa ko hajyaho ibizunguruka bishya (IC).

Isoko rya PMIC riratera imbere cyane kubera impinduka nyinshi zigezweho.Icyerekezo kimwe ni ugukurikirana abaguzi kugendanwa bidafite umugozi, ibyo bikaba byaratumye abantu benshi bakeneye ibikoresho bito, bikoreshwa na batiri ndetse nibikenewe kugirango bishoboke gukemura ibibazo byinshi.
Muri icyo gihe, hari byinshi byiyongera ku baguzi no mu nganda ku bicuruzwa bikoresha ingufu kandi bigabanya imyuka ihumanya ikirere.Icyerekezo "icyatsi" ku isi cyongereye ibicuruzwa bya elegitoronike hamwe no gucunga neza ingufu, bituma imicungire y’amashanyarazi ari ikintu cyingenzi kandi gikunzwe.

Imikorere nyamukuru

Imikorere nyamukuru ya PMIC: [gucunga ingufu, kugenzura kwishyuza, guhinduranya imiyoboro]

- Guhindura DC-DC
- Umuyoboro muto wa Dropout Umuyoboro (LDO)
- Amashanyarazi
- Guhitamo amashanyarazi
- Amashanyarazi ya Dynamic
- Imbaraga kuri / kuzimya kugenzura kuri buri mashanyarazi
- Kugaragaza amashanyarazi kuri buri mashanyarazi
- Kumenya ubushyuhe
- Indi mirimo

Uko amashanyarazi menshi PMIC afite, niko gutanga amashanyarazi kuri module ya sisitemu, ntago amashanyarazi atangwa kuri buri module abigiramo uruhare, bityo rero kuzigama ingufu.
