I-Slkor® SL4054 Li-Ion Isixazululo Sokulawulwa Kwebhethri

Mayelana no-Slkor:

Neqembu elikhethekile elithweswe iziqu e-Beijing Tsinghua University, i-Shenzhen SlkorMicro Semicon Co., Ltd. inikezelwe kumadivayisi kagesi esizukulwane sesithathu semiconductor SiC. I-Slkor iyibhizinisi likazwelonke lobuchwepheshe obuphezulu elimboza i-R&D, insizakalo yokukhiqiza nokudayisa yamadivayisi e-semiconductor futhi ihlinzeka ngemikhiqizo ethembekile kanye nezinsizakalo zobuchwepheshe ezisekelayo kumakhasimende.

Ukuze usize izinkampani zezixazululo zomkhiqizo we-elekthronikhi, onjiniyela bezinhlelo ze-elekthronikhi, nabashisekeli bezinto zikagesi ukuthi bazuze ngokugcwele ngemikhiqizo ye-Slkor, onjiniyela abavela e-Slkor bakhethe izimo ezivamile ezinhlelweni zeklayenti ukuze babelane nawo wonke umuntu.

1.1. TIle: Ishaja ye-Slkor® SL4054 Linear Li-Ion

1.2. Applications: Ukushaja Okunamandla e-USB, Amakhompuyutha Aphathwayo, Izidlali zeMP3, Izifakwandlebeni zeBluetooth, Amakhamera Edijithali, Omakhalekhukhwini, iPDA.

1.3. Incazelo:

I-Slkor?4054 iyishaja yomugqa ongaguquguquki yamanje/eqhubekayo-voltage yamabhethri e-lithium-ion yeseli elilodwa. Iphakheji layo le-SOP nokubalwa kwengxenye yangaphandle ephansi kwenza i-SL4054 ifanelekele izinhlelo zokusebenza eziphathwayo. Ngaphezu kwalokho, i-SL4054 ingasebenza ngaphakathi kwe-USB ne-adaptha yodonga. Ayikho i-diode evimbelayo edingekayo ngenxa yesakhiwo sangaphakathi se-PMOSFET futhi inokuvimbela ukuya ku-negative Charge Current Circuit. Impendulo eshisayo ilawula ukushajwa kwamanje ukuze kukhawulwe izinga lokushisa lokufa ngesikhathi sokusebenza kwamandla aphezulu noma izinga lokushisa eliphezulu le-ambient. I-voltage yokushaja igxilwe ku-4.2V, futhi i-charge yamanje ingahlelwa ngaphandle nge-resistor eyodwa. I-SL4054 inqamula ngokuzenzakalelayo umjikelezo wokushaja lapho ukushajwa kwamanje kwehlela ku-1/10 inani elihleliwe ngemva kokuba kufinyelelwe i-voltage yokugcina yokuntanta. Lapho ukhipha amandla okokufaka ngokuzenzekelayo kubeka i-SL4054 kumodi yamanje ephansi ukuze kuncishiswe ukuvuza kwamanje kwebhethri kube ngaphansi kuka-2uA, futhi imodi yokuvala shaqa inciphisa ukunikezwa kwamanje ku-45μA. I-SL4054 Ezinye izici zifaka i-monitor yamanje, ngaphansi kwe-voltage lockout, ukushajwa kabusha okuzenzakalelayo namaphinikhodi amabili okukhombisa ukunqanyulwa kweshaji kanye nokuba khona kwe-voltage yokufaka. I-Slkor? I-SL4054 iyatholakala ku-SOT23-5 (ThinSOT^TM) iphakethe.

2. I-Slkor® SL4054 Umjikelezo Wesicelo Ojwayelekile:

3.1. Ci-harging Cycle:

Lapho i-voltage itholakala ku-V_cc iphinikhodi iphakama ngaphezu kweleveli yomkhawulo we-UVLO futhi isiphikisa sokusetha esinembayo esingu-1% sixhunywe phakathi kwephinikhodi ye-PROG nephinikhodi ye-GND, noma uma ibhethri lixhunywe kokuphumayo kweshaja, umjikelezo wokushaja uyaqala. Uma i-voltage kuphinikhodi ye-BAT ingaphansi kuka-2.9V, ishaja ingena kumodi yokushaja kancane. Kule modi, i-SL4054 inikeza cishe u-1/10 wesethi yokushaja yamanje ukuze ikhuphule i-voltage yamanje ibe sezingeni eliphephile ukuze ishajwe ngokugcwele. Lapho i-voltage kuphinikhodi ye-BAT iphakama ngaphezu kuka-2.9V, ishaja ingena kumodi yamanje engashintshi futhi inikeze ibhethri amandla akhona ashajayo. Lapho i-voltage kuphini ye-BAT ifinyelela ku-voltage yokugcina yokushaja okuntantayo (4.2V), i-SL4054 ingena kumodi ye-voltage engaguquki futhi ukushaja kwamanje kuqala ukuncipha. Umjikelezo wokushaja uphela lapho ukushaja kwamanje kwehlela ku-1/10 yenani elimisiwe.

3.2. I-Constant Charge Setting yamanje:

Ukushaja kwamanje kusethwa ngokuxhuma i-resistor R_ISET kusuka ku-PROG(Pin 5) kuya ku-GND. Inani le-resistor kanye namandla okushaja kubalwa ngokulandelayo: (nquma inani lokumelana le-resistor ngokusekelwe kumanje ukushaja oyifunayo).

3.3. Ci-harging Tukuqedwa:

Lapho amandla okushaja afinyelela ku-voltage yokugcina ye-float futhi yehla ibe ngu-1/10 yenani elimisiwe, umjikelezo wokushaja uyanqanyulwa. Lesi simo sitholwa ngokuqapha iphinikhodi ye-PROG kusetshenziswa isifanisi sokuhlunga sangaphakathi. Lapho i-voltage kuphinikhodi ye-PROG yehla ibe ngu-100mV, ukushaja kuyanqanyulwa. Umshini wokushaja uyanqanyulwa, bese i-SL4054 ingena kumodi yokulinda, amandla okufaka ehlela ku-45uA.

3.4. I-Undervoltage Lockout:

Isekhethi ye-internal undervoltage lockout (UVLO) iqapha amandla kagesi okufakwayo futhi igcina ishaja ikumodi yokuvala shaqa kuze kube yilapho i-VCC ikhuphuka ngaphezu komkhawulo we-UVLO. Uma isifanisi se-UVLO sihlangabezana noshintsho, ishaja ngeke iphume kumodi yokuvala kuze kube yilapho i-Vcc ikhuphuka ngaphezu kwamandla ebhethri ngo-100mV.

4. I-BOM ye Slkor? SL4054 Ukusetshenziswa Okujwayelekile

amanothi:

1. Ukusebenza kwamanje kwe-chip kuhlanganisa okwamanje okudliwe yi-resistor yangaphandle exhunywe kuphinikhodi ye-PROG (cishe u-100uA), kodwa ayifaki yamanje esetshenziswa chip ukuzishaja yona ngephinikhodi ye-BAT (cishe u-100mA).

2. Ukuphela kwesikhathi sokushaja ngokuvamile siwuphinda izikhathi ezingu-0.1 kunesethi yamanje yokushaja.

Kwa-Slkor, sisebenza kanzima ukuze sinikeze izinsizakalo ezichwepheshile neziphelele. Sinomugqa ophelele womkhiqizo osukela kuzinhlelo zokusebenza zezimboni kuya ezinhlelweni zokusebenza, ama-SiC diode, i-SiC MOSFET, i-IGBT, isizukulwane sesi-5 samandla okuthola kabusha okusheshayo, njll. Le mikhiqizo isetshenziswa kakhulu ezimotweni zikagesi, izinto ezisezingeni eliphezulu, izinto zokuxhumana, amathuluzi kagesi kagesi, amasistimu e-solar photovoltaic kanye nemishini yezokwelapha nokunye. Ngemikhiqizo yabathengi, sinikezela nge-MOS, i-SCR, amabhuloho alungisa kabusha amandla kagesi aphezulu naphansi, ama-Schottky diode, ama-diode okuvikela e-ESD, ama-TVS, ama-diode enhloso evamile nama-transistors, ama-IC okuphatha amandla, izinzwa zehholo, ama-optical couplers anesivinini esiphezulu, ama-crystal oscillator, njll. IoV, izibani ze-LED, imikhiqizo yedijithali ye-3C neminye imikhakha. Sicela ugcine othintana nabo eduze, sizokwethula imikhiqizo eminingi yedijithali ne-analog IC ukuze sihlangabezane nezidingo zakho.
