I-LP87702DRHBRQ1 Umgangatho oMtsha oMtsha kunye neyoqobo ye-IC ye-IC eDityanisiweyo yeSekethe yeSibonelelo soMfanekiso oFanelekileyo

inkcazelo emfutshane:

I-LP87702-Q1 inceda ukuhlangabezana neemfuno zolawulo lwamandla kumaqonga amva nje, ngakumbi kwirada yeemoto kunye nekhamera kunye nezicelo zerada yeshishini.Isixhobo siqulethe iziguquli ezimbini ze-DC / DC ezisezantsi, kunye ne-5-V yokunyusa i-converter ukuxhasa izicelo ezibalulekileyo zokhuseleko.Isixhobo sidibanisa iigalelo ezimbini zokubeka iliso kwi-voltage kunikezelo lwamandla lwangaphandle kunye ne-window watchdog.
Ukusebenza okuzenzekelayo kwe-PWM/PFM (imowudi ye-AUTO) inika ukusebenza kakuhle okuphezulu ngaphezulu koluhlu olubanzi lwemveliso yangoku kubaguquli bebhaki.I-LP87702-Q1 isebenzisa i-remote voltage sensing ukubuyisela i-IR drop phakathi kwe-converter output kunye ne-point-of-load, ngaloo ndlela iphucula ukuchaneka kombane wokuphuma.

PMIC?

I. Yintoni i-PMIC
I-PMIC sisishunqulelo solawulo lwamandla e-IC, eyona nto iphambili yidigri ephezulu yokudibanisa, iphakheji yesiqhelo yonikezelo lwamandla amaninzi kwi-chip ukwenzela ukuba imeko yesicelo samandla amaninzi inokusebenza okuphezulu, kunye nobukhulu obuncinci.Ii-PMICs zihlala zisetyenziswa kwiinkqubo ze-CPU, ezifana noyilo lwebhokisi yokumisela, uyilo lwesithethi selizwi esikrelekrele, uyilo olukhulu lwezixhobo zolawulo lwamashishini, njl.
I-PMIC enye inokulawula unikezelo lwamandla amaninzi angaphandle, ukwenza imephu yeemfuno zenkqubo eyahlukileyo kumbane ofanelekileyo wokuphuma komlawuli.Zingaphinda zisetyenziswe kwiiprosesa ezahlukeneyo, abalawuli benkqubo, kunye nezicelo zokuphela, ezifuna kuphela utshintsho kwimimiselo yerejista echaphazelekayo okanye i-firmware, ngaphandle kwesidingo sokuhlaziya isiphaluka esitsha esihlanganisiweyo (IC).

Imakethi ye-PMIC ikhula ngokuxhuma kunye nemida ngenxa yeentsingiselo ezininzi zangoku.Omnye umkhwa kukufuna komthengi ukushukumiseka okungenazingcingo, okudale imfuno enkulu yezixhobo ezincinci, ezisebenza ngebhetri kunye nesiphumo semfuno yezisombululo zolawulo lwamandla oludityanisiweyo kakhulu.
Ngexesha elifanayo, kukho imfuno ekhulayo evela kubathengi kunye nabavelisi beemveliso ezisebenza ngamandla kunye nokunciphisa ukukhutshwa kwekhabhoni.Inkqubo "eluhlaza" yehlabathi inyuse imfuno yeemveliso ze-elektroniki ezinolawulo olusebenzayo lwamandla, nto leyo eyenza ukuba ulawulo lwamandla lube yinto ebaluleke kakhulu nethandwayo.

Imisebenzi ephambili

Imisebenzi ephambili ye-PMIC: [ulawulo lwamandla, ulawulo lokutshaja, ukutshintshwa kolawulo lwesekethe]

- DC-DC converter
-I-Lower Dropout Voltage Regulator (LDO)
- Itshaja yebhetri
- Ukukhetha unikezelo lwamandla
- Ukulawulwa kwamandla ombane anamandla
- Ukuvula/ukucima ulawulo lolandelelwano kunikezelo lwamandla ngamnye
- Ukubona iVoloji kunikezelo lwamandla ngamnye
- Ukufunyanwa kobushushu
- Eminye imisebenzi

Okukhona amandla okubonelela nge-PMIC enawo, kokukhona unikezelo lwamandla olugqwesileyo kwiimodyuli zenkqubo, kokukhona unikezelo lwamandla oluncinci lwemodyuli nganye lubandakanyekayo, kwaye ke ngoko ukonga umbane ngakumbi.
