1.3. Tlhaloso:

Slkor?4054 ke tjhaja e felletseng ya kamehla-ya jwale/ya kamehla-ya motlakase bakeng sa dibetri tsa lithium-ion tsa sele e le nngwe. Sephutheloana sa eona sa SOP le palo e tlase ea likarolo tsa kantle li etsa hore SL4054 e lokele lits'ebetso tse nkehang habonolo. Ho feta moo, SL4054 e ka sebetsa ka har'a USB le adaptara ea lebota. Ha ho na diode e thibelang e hlokahalang ka lebaka la meralo ea ka hare ea PMOSFET 'me e na le thibelo ea ho Charge Current Circuit e fosahetseng. Maikutlo a mocheso a laola tefiso ea hona joale ho fokotsa mocheso oa mocheso nakong ea ts'ebetso ea matla a phahameng kapa mocheso o phahameng oa tikoloho. Motlakase oa tefiso o tsitsitse ho 4.2V, 'me motlakase oa motlakase o ka hlophisoa ka ntle ka mochine o le mong. SL4054 e emisa ka bo eona potoloho ea tefiso ha tefiso ea hona joale e theohela ho 1/10th boleng bo hlophisitsoeng ka mor'a hore motlakase oa ho qetela oa float o fihle. Ha o tlosa matla a ho kenya ka bohona o beha SL4054 mokhoeng o tlase oa hajoale ho fokotsa ho lutla ha betri ho tlase ho 2uA, mme mokhoa oa ho koala o fokotsa phepelo ea hajoale ho 45μA. SL4054 Likarolo tse ling li kenyelletsa sebali sa hajoale, tlas'a ho notleloa ha voltage, recharge ea othomathiki le phini e 'meli ea boemo ho bonts'a ho felisoa ha tefiso le boteng ba motlakase o kenang. Slkor? SL4054 e fumaneha ho SOT23-5 (ThinSOT^TM) sephutheloana.

3.1. Charing Cycle:

Ha motlakase oa V_cc pin e phahama ka holim'a moeli oa UVLO 'me mochine o nepahetseng oa 1% oa ho seta o hokahane pakeng tsa phini ea PROG le phini ea GND, kapa ha betri e hokahane le tlhahiso ea tjhaja, potoloho ea ho tjhaja e qala. Haeba motlakase oa pini ea BAT o le ka tlase ho 2.9V, tjhaja e kena ka mokhoa o fokolang oa ho tjhaja. Mokhoeng ona, SL4054 e fana ka hoo e ka bang 1/10 ea sete ea ho tjhaja hona joale ho phahamisa motlakase oa hona joale sebakeng se sireletsehileng bakeng sa ho tjhaja ka botlalo. Ha motlakase oa pini ea BAT o phahama ka holimo ho 2.9V, tjhaja e kena ka mokhoa o tsitsitseng oa hona joale 'me e fana ka motlakase o sa khaotseng ho betri. Ha motlakase oa pini ea BAT o fihla ho motlakase oa ho qetela oa float (4.2V), SL4054 e kena ka mokhoa o tsitsitseng oa motlakase 'me hona joale ho tjhaja ho qala ho fokotseha. Potoloho ea ho tjhaja e fela ha ho tjhaja hona jwale ho theohela ho 1/10 ya boleng bo behilweng.

3.2. Litlhophiso tsa hajoale tsa Tefiso:

Chaji ea hajoale e hlophisoa ka ho hokela sehanyetsi sa R_ISET ho tloha ho PROG(Pin 5) ho ea ho GND. Boleng ba mohanyetsi le motlakase oa ho tjhaja li baloa ka tsela e latelang: (etsa qeto ea boleng ba khanyetso ea mohanyetsi ho latela mochine o batlang ho tjhaja).

3.3. Charing Tho felisoa:

Ha motlakase oa ho tjhaja o fihla ho motlakase oa ho qetela oa float mme o fokotseha ho 1/10 ea boleng bo behiloeng, potoloho ea ho tjhaja e felisoa. Boemo bona bo bonoa ka ho beha leihlo phini ea PROG ho sebelisa sebapi sa ho sefa ka hare. Ha motlakase oa pini ea PROG o theohela ho 100mV, ho tjhaja ho felisoe. Mohala oa ho tjhaja o khaotsoe, 'me SL4054 e kena boemong ba standby, ha motlakase o kenang o theohela ho 45uA.

3.4. Undervoltage Lockout:

Internal undervoltage Lockout (UVLO) e hlokomela motlakase o kenang 'me e boloka tjhaja e le ho tima ho fihlela VCC e nyolohela ka holim'a moeli oa UVLO. Haeba sebali sa UVLO se ka ba le phetoho, tjhaja e ke ke ea tsoa nakong ea ho tima ho fihlela Vcc e nyoloha ka holim'a matla a betri ka 100mV.
