Kungani kungasetshenziswa unogada oyedwa ochungechungeni

Lapho izingxenye eziningi zebhodi lokulungisa ibhethri ye-lithium zixhunywe ochungechungeni, izinkinga ezilandelayo zingase zenzeke:

1: Ukushaja: thatha ibhethri engu-4.2 V ukugcinwa kwamandla kagesi, okufana nokugcinwa kwepayipi lokushaja ipuleti le-B, ukumelana okungapheli kwangaphakathi, kulokhu, izindawo zokunqanyulwa kweshubhu zamanje, kanye nesigaba esisodwa esijwayelekile sebhodi le-lithium yebhethri yesondlo senkundla yomphumela weshubhu ukucindezela kukhulu kakhulu. kuphansi, ngakho-ke kungase kudilike, kodwa ngenxa yesimo sokushaja, ukushaja ukwehla kwamanje ngaphezu kwayo yonke i-voltage yebhethri, okujwayelekile ngeke kuvele into yokucindezela ngokweqile), ngemva kokulungisa kanye nelinye ishubhu lokushaja B, i-voltage yokushaja ingaba Ukwengeza indawo eyodwa yephaneli yokulungisa i-VDD ingase ibonakale i-overvoltage, okuholela ekulimaleni ekugcinweni kwephaneli ehlanganisiwe B.

2: ukukhishwa: kucatshangelwa ukulungiswa kwe-voltage yebhethri engu-2.7V, njengepuleti yokulungisa i-Dout yokushaja ishubhu ukulungisa, ukumelana okungapheli kwangaphakathi, kulokhu, iphoyinti leshubhu lamanje, kulokhu uma isifunda ngaphakathi kukhona amabhethri ayisithupha, ngakho-ke ithubhu izoba I-voltage engu-25 V, indingilizi eluhlaza kumdwebo we-Dout field effect tube soft ukwehluleka, ngakho-ke, ngisho nasemsebenzini wokulungisa, Kukhona nezinye izicathulo zamahhashi okuthi, uma zilimele ngokuphelele, zizoba namandla amanje ngokulahlekelwa nokulungisa. Ngemuva kokuthi ithubhu isilungisiwe, ingcindezi yangemuva kusukela ekupheleni kwe-V yebhodi A kuya ekupheleni kwe-VSS yebhodi A iphezulu njenge-25V, futhi ingcindezi yangemuva kusukela ekupheleni kwe-V kuya ekupheleni kwe-VDD imayelana ne-21V, engase ibangele ngokuphelele i-chip. umonakalo.

Okunye ukuhlaziya ngenhla, kuyaphawuleka ukuthi insimu effect tube ezimbili idivayisi ebhuthini, ngaphansi kwezimo ezivamile, ngisho ngaphandle voltage ukushayela, wamanje kagesi kungase futhi kube imisebenzi isiqondiso umcibisholo icon, ezifana sibalo ngenhla dout high voltage kanye zamanje kungaba okuhlanekezelwe, umcibisholo wehlisa amandla aphansi, okwamanje ngokuhambisana kuphela nomsebenzi womcibisholo futhi, kodwa isiqondiso somsebenzi womcibisholo siphelile. Ngakho-ke, i-DOUT iyitheminali yokulawula ukukhipha.

Ngaphansi kwezimo ezijwayelekile, singahamba siye ngakumcibisholo ngaphandle kokwengeza amandla, kodwa kuzoba nokwehla kwengcindezi cishe ngo-0.3V. Ngakho-ke, ukuze kuqedwe ukwehla kwamandla kagesi kwangaphakathi futhi wengeze izinga eliphezulu, ukwehla kwamandla kagesi angaphakathi endaweni yomcibisholo kuzosondela kuma-millivolts ambalwa kuya kumashumi amamilivolthi. Ngakho-ke, i-MOSFETT iyithuluzi lokulawula izinkomba ezimbili.
