I-PMIC - Amashaja Ebhethri

Isingeniso Somkhiqizo

I-chip yeshaja yebhethri iyi-chip engakwazi ukushaja futhi ilawule amabhethri amaningi, kusukela kubhethri elilodwa le-lithium, ibhethri elilodwa le-lithium iron phosphate, noma amabhethri e-NiMH amabili kuya kwamane.

Izinkomba Zokusebenza

Izidingo eziyinhloko zamashaja esimanje yizikhathi ezimfushane zokushaja nokuphepha (akukho monakalo ebhethrini nempilo yebhethri efinyeziwe).Lokhu kudinga ishaja enesekhethi ehlanganisiwe ekwazi ukushayela amaza aphezulu kanye nekhono eliqinile lokubona kanye nenqubo yokushaja ephelele.Ngokuvamile, amashaja asheshayo anesikhathi sokushaja esingaphansi kwehora elilodwa futhi ngenxa yalokho adinga amandla ombane aphezulu.

Mayelana Nemikhiqizo

I-BQ25896 iyisisetshenziswa sokuphatha ukushajwa kwebhethri yemodi yokushintsha engu-3-A edidiyelwe kakhulu kanye nedivayisi yokulawula indlela yamandla yeseli eyodwa i-Li-Ion nebhethri le-Li-polymer.Amadivayisi asekela ukushaja okusheshayo kwe-voltage ephezulu.Indlela yamandla e-impedance ephansi ilungiselela ukusebenza kahle kwemodi yokushintsha, inciphisa isikhathi sokushajwa kwebhethri futhi inwebe impilo yebhethri phakathi nesigaba sokushajwa.I-interface ye-I2C Serial enezilungiselelo zokushaja nesistimu yenza idivayisi ibe yisixazululo esivumelana nezimo ngempela.
Idivayisi isekela imithombo yokufaka eyahlukene futhi ithatha umphumela ekutholeni umjikelezo ohlelweni, njengedivayisi ye-USB PHY.Ukukhethwa kokufakwayo kwamanje kanye nokulawulwa kwamandla kagesi kuyahambisana ne-USB 2.0 kanye ne-USB 3.0 power spec.Ngaphezu kwalokho, I-Input Current Optimizer (ICO) isekela ukutholwa kwephoyinti lamandla eliphakeme kakhulu lomthombo wokufaka ngaphandle kokugcwala kakhulu.Idivayisi futhi ihlangabezana nokucaciswa kwesilinganiso samandla okusebenza kwe-USB On-the-Go (OTG) ngokunikeza i-5 V (Adjustable 4.5V-5.5V) ku-VBUS enomkhawulo wamanje ofika ku-2 A.
Ukuphathwa kwendlela yamandla kulawula isistimu ngaphezulu kwe-voltage yebhethri kodwa awehli ngaphansi kuka-3.5V ubuncane be-voltage yesistimu (ehlelekayo).Ngalesi sici, isistimu igcina ukusebenza ngisho nalapho ibhethri seliphelile noma likhishiwe.Uma umkhawulo wamanje wokufakwayo noma umkhawulo we-voltage ufinyelelwa, ukuphathwa kwendlela yamandla kwehlisa ngokuzenzakalelayo ukushajwa kwamanje kuye kuqanda.Njengoba umthwalo wesistimu uqhubeka ukwanda, indlela yamandla ikhipha ibhethri kuze kuhlangatshezwane nemfuneko yamandla esistimu.
Lokhu kusebenza Kwemodi Yokwengeza kuvimbela ukugcwala ngokweqile komthombo wokufaka.
Idivayisi iphinde inikeze i-7-bit analog-to-digital converter (ADC) yokuqapha amandla omthamo wamanje kanye nokokufaka/ibhethri/uhlelo (VBUS, BAT, SYS, TS).Iphinikhodi ye-QON inikeza i-BATFET ukunika amandla/ukusetha kabusha ukulawula ukuphuma kumodi yomkhumbi wamandla aphansi noma umsebenzi wokusetha kabusha uhlelo olugcwele.
Umndeni wedivayisi utholakala ngephakeji ye-WQFN engu-24-pin, 4 x 4 mm2 x 0.75 mm izacile.

Amathrendi Akusasa

Ikusasa liyathembisa kuma-chips okuphatha amandla.Ngokuthuthukiswa kwezinqubo ezintsha, ukupakisha, namasu okuklama isekethe, kuzoba namadivayisi asebenza kangcono nakakhulu.Angakwazi ukuthuthukisa ukuminyana kwamandla, anwebe ukuphila kwebhethri, anciphise ukuphazamiseka kukazibuthe kagesi, athuthukise amandla nobuqotho besignali futhi athuthukise ukuphepha kwesistimu, asize onjiniyela emhlabeni wonke ukuba bathole ukusungula izinto ezintsha.
