Slkor SL4056 Li-Ion Taolo ea Battery Tharollo

Mabapi le Slkor:

Ka sehlopha sa batho ba maemo a holimo se fumaneng mangolo Univesithing ea Beijing Tsinghua, Shenzhen SlkorMicro Semicon Co., Ltd. e etselitsoe lisebelisoa tsa motlakase tsa SiC tsa moloko oa boraro. Slkor ke khamphani ea naha ea theknoloji e phahameng e sebetsanang le R&D, tlhahiso le tšebeletso ea thekiso ea lisebelisoa tsa semiconductor mme e fana ka lihlahisoa tse tšepahalang le lits'ebeletso tsa tekheniki ho bareki.

E le ho thusa lik'hamphani tsa tharollo ea lihlahisoa tsa elektroniki, lienjiniere tsa ts'ebeliso ea elektroniki, le ba chesehelang lisebelisoa tsa elektroniki ho sebelisa lihlahisoa tsa Slkor hamolemo, lienjiniere tsa Slkor li khethile linyeoe tse tloaelehileng ho tsoa lits'ebetsong tsa bareki ho li arolelana le motho e mong le e mong.

1.3. Tlhaloso:

Slkor 4056 ke tjhaja e nang le tjhaja e theko e tlase bakeng sa betri e le 'ngoe ea lithium-ion. E na le profil ea tjhaja ea CC/CV e hlokehang bakeng sa betri ea Li-Ion. Tefiso ea hona joale le nako ea tefiso e behiloe ka ntle ka mochine o le mong le capacitor, ka ho latellana, tekanyo e phahameng ea ho tjhaja e ka fihla ho 1A. SL4056 e na le lithakhisa tse peli tse bulehileng bakeng sa sesupo sa boemo, e leng pin ea charging status indicator (CHRG) le pini ea indicator e tjhaetsoeng ka botlalo (STDBY). Potoloho ea matla ea MOSFET ka har'a chip e fokotsa hona joale ea ho tjhaja ka bo eona ha mocheso oa mateano oa chip o feta 135 ℃. Karolo ena e lumella basebelisi ho eketsa tšebeliso ea chip bakeng sa ho tjhaja ntle le ho tšoenyeha ka ho chesa le ho senya chip kapa likarolo tsa kantle. Slkor? SL4056 e fumaneha ka har'a sephutheloana sa ESOP8.

3.1. Molao-motheo oa ho tjhaja:

Ha motlakase oa ho kenya o phahame ho feta moeli oa ho lemoha oa UVLO 'me chip e nolofalletsa ho kenya CE e behiloe boemong bo phahameng, SL4056 e qala ho tjhaja betri. Nako ea ho tjhaja e khethoa ke sehanyetsi pakeng tsa phini ea PROG le phini ea GND. Ha matla a betri a atamela 4.2V, motlakase oa ho tjhaja o fokotseha butle-butle, 'me SL4056 e kena ka mokhoa o tsitsitseng oa ho tjhaja motlakase. Potoloho ea ho tjhaja e fela ha motlakase oa ho tjhaja o theoha ho fihla moeling oa ho emisa ho tjhaja, e leng 1/10 ea nako e sa khaotseng ea ho tjhaja hona joale. Ha motlakase oa betri o theoha ka tlase ho moeli oa ho tjhaja hape, potoloho e ncha ea ho tjhaja e qala ka bo eona. Mohloli oa ka hare oa chip, seamplifier le marang-rang a li-resistor divider li netefatsa hore motlakase oa modulation pineng ea BAT o nepahetse ka har'a 1%, o fihlela litlhoko tsa libeteri tsa lithium-ion le lithium-polymer. Ha motlakase o tlositsoe kapa o koalehile ka letsoho, tjhaja e tla hula feela maqhubu a manyane a lutla (<2μA) ho tsoa betiring, kahoo e eketsa nako ea ho ema ha betri. Haeba pini ea CE e behiloe boemong bo tlase, tjhaja e emisa ho tjhaja.

3.3. Palo ea boleng ba R1 le R2 e ka hlalosoa ka tsela e latelang:

Ho fumana boleng ba R1 le R2 ho latela mocheso oa mocheso oa betri le boleng ba khanyetso ba thermistor. Ka mohlala: ho nka hore mocheso oa mocheso oa betri ke TL ho TH (moo TL <TH), 'me betri e sebelisa mocheso o mobe oa mocheso oa mocheso oa mocheso (NTC) o nang le RTL e le ho hanyetsa mocheso oa TL le RTH e le ho hanyetsa mocheso oa TH. Ho latela hore RTL > RTH.
