Kopo le molao-motheo oa icR5426 o kopantsoeng mohloling oa betri ea lithium:
E hlahisitse ts’ebeliso le molao-motheo oa ts’ebetso oa chip ea R5426 ho microcontroller
Matsatsing ana, lihlahisoa tsa elektronike tse nkehang habobebe li ntse li tsebahala haholoanyane, ‘me lisebelisoa tsa bona tsa betri li se li lebisitsoe tlhokomelong ea tsona. Libetri tsa lithium le libeteri tsa polymer lithium butle-butle li nkile sebaka sa libeteri tsa nickel-cadmium le libeteri tsa nickel-hydrogen e le khetho ea pele bakeng sa lisebelisoa tse nkehang ka lebaka la matla a tsona a matla, nako e telele ea tšebeliso, le litlhoko tse phahameng tsa tšireletso ea tikoloho. Ricoh’s lithium-ion repair chip R5426 series e etselitsoe ka ho khetheha lisebelisoa tse nkehang joaloka mehala ea cellular, pdas, le libeteri tsa monolithic lithium.
R5426 series ke overcharge/decharge/overcurrent maintenance chip, e ka lefisoang ka lithium ion/betri.
Letoto la R5426 le entsoe ka theknoloji e phahameng ea motlakase, e mamellang voltage e seng ka tlase ho 28V, e kentsoeng ka 6-PIN, SOT23-6 kapa SON-6, ka tšebeliso e tlase ea matla (motlakase o tloaelehileng oa boleng ba 3.0UA, boleng bo tloaelehileng ba hajoale ba 0.1UA. ), tekanyo e phahameng ea ho lemoha ka mokhoa o nepahetseng, menyako e fapaneng ea moeli oa tlhokomelo, ho kenngoa ha ho lieha ha tlhahiso ea tlhahiso le mesebetsi ea ho tjhaja 0V, tlhokomelo ea ts’ebetso ka mor’a ho netefatsa.
Potoloho e ‘ngoe le e’ ngoe e kopantsoeng e na le lisebelisoa tse ‘nè tsa motlakase, mochine oa potoloho ea litšupiso, potoloho ea ho lieha, molebeli oa potoloho e khutšoanyane, oscillator, counter le logic circuit. Ha motlakase oa ho tjhaja le ho tjhaja o ntse o eketseha ho tloha ho tse nyane ho isa ho tse kholo mme o feta li-detectors tse tsamaellanang tsa monyako (VD1, VD4), pini ea tlhahiso ea Cout e fetisoa ke mochini o hlahisang motlakase / VD1 ho e boloka, ‘me sesebelisoa sa overcurrent / VD4 se feta. comparing/ Ho dieha ha ka hare ho fetoha boemong bo tlase. Kamora hore betri e tjhaje ho feta tekano kapa ho tjhajwa ho feta tekano, ntsha pakete ya betri ho tjhaja mme o hokele moroalo ho VDD. Ha matla a betri a theoha ka tlase ho boleng bo holimo, li-detectors tse peli tse lumellanang (VD1 le VD4) li tsosolosoa, ‘me tlhahiso ea Cout e ba e phahameng. Haeba pakete ea betri e ntse e le ka har’a tjhaja, le haeba matla a betri a le tlase ho boleng ba teko ea tjhaji e fetang tekano, tlhokomelo ea tjhaja e fetang tekano e ke ke ea lokolloa.
Pin ea DOUT ke phini ea tlhahiso ea mochine oa ho ntša metsi ho feta tekano (VD2) le mochine o hlahlobang ho feta tekano (VD3). Ha matla a ho ntša motlakase a le tlase ho feta VDET2 ea motlakase oa overdischarge ho tloha holimo ho ea tlaase, ke hore, ka tlaase ho VDET2, pinana ea DOUT e theohela tlaase ka mor’a ho lieha ho tsitsitseng ka hare.
Ka mor’a ho lemoha ho tsoa ho feta tekano, haeba tjhaja e hokahane le pakete ea betri, ha motlakase oa phepelo ea betri o phahame ho feta moeli oa motlakase oa motlakase o feteletseng, VD2 e lokolloa ‘me DOUT e phahama.
E hahiloe ka ho fetisisa-hona joale / e khutšoanyane ea mochine oa mochine oa VD3, ka mor’a ho lieha ho tsitsitseng, ka ho fetola tlhahiso ea DOUT ho ea boemong bo tlaase, boemo ba ho tsoa ho feta hona joale bo utloahala ‘me ho ntšoa hoa khaoloa. Kapa ha nako e khutšoanyane ea potoloho e fumanoa, boleng ba DOUT bo fokotseha hang-hang, ‘me ho tsoa hoa khaoloa. Hang ha potoloho ea overcurrent kapa e khutšoanyane e fumanoa, pakete ea betri e arohane le mojaro, VD3 e lokolloa, ‘me boemo ba DOUT bo eketseha.
Ho phaella moo, ka mor’a ho lemoha ho tsoa, chip e tla emisa ts’ebetso ea potoloho ea ka hare ho boloka matla a sebelisoang haholo. Ka ho beha terminal ea DS boemong bo lekanang le ea VDD, tieho ea tlhokomelo e ka khutsufatsoa (ntle le tlhokomelo ea potoloho e khutšoane). Haholo-holo, ho lieha ho boloka chelete e ngata ho ka fokotsoa ho 1/90, e leng ho fokotsang nako e hlokahalang ea ho hlahloba le ho boloka potoloho. Ha boemo ba DS bo setiloe ka har’a sebaka se itseng, tieho ea tlhahiso e ea hlakoloa, ‘me tefiso e fetelletseng le hona joale ea tefiso e fetelletseng li bonoa hang-hang. Ka nako ena, tieho e ka ba mashome a li-microseconds.
