Taw qhia daim ntawv thov thiab cov hauv paus ntsiab lus ua haujlwm ntawm R5426 nti hauv microcontroller

Niaj hnub no, cov khoom siv hluav taws xob portable tau dhau los ua neeg nyiam, thiab lawv cov khoom siv roj teeb tau dhau los ua qhov tseem ceeb ntawm kev mloog. Cov roj teeb lithium thiab cov roj teeb polymer lithium tau maj mam hloov cov roj teeb nickel-cadmium thiab cov roj teeb nickel-hydrogen uas yog thawj qhov kev xaiv rau cov khoom siv nqa tau vim lawv lub zog siab ceev, siv sijhawm ntev, thiab kev tiv thaiv ib puag ncig siab. Ricoh’s lithium-ion kho nti R5426 series yog tsim tshwj xeeb rau cov khoom siv thauj khoom xws li xov tooj ntawm tes, pdas, thiab cov roj teeb lithium monolithic.

R5426 series yog overcharge / tawm / overcurrent tu nti, uas tuaj yeem them nrog lithium ion / roj teeb.

R5426 series yog tsim los nrog high voltage technology, withstand voltage tsis tsawg tshaj li 28V, ntim rau hauv 6-PIN, SOT23-6 los yog SON-6, nrog tsawg zog noj (tus nqi fais fab tam sim no ntawm 3.0UA, raug standby tam sim no tus nqi ntawm 0.1UA ), high precision Detection pib, ntau yam kev txij nkawm txwv qhov pib, ua-nyob rau hauv tso zis ncua sij hawm them thiab 0V them zog, kev ua haujlwm txij nkawm tom qab kev pom zoo.

Txhua qhov kev sib xyaw ua ke muaj plaub lub ntsuas hluav taws xob, lub ntsuas hluav taws xob siv hluav taws xob, lub voj voog qeeb, tus neeg saib xyuas luv luv, lub oscillator, lub txee thiab lub logic Circuit Court. Thaum lub charger voltage thiab them tam sim no nce los ntawm me me mus rau qhov loj thiab tshaj qhov sib thooj qhov pib detectors (VD1, VD4), cov zis tus pin Cout yog overcharged los ntawm cov zis voltage ntes / VD1 los tswj, thiab overcharge thiab overcurrent detector / VD4 hla lub sib thooj Lub internal ncua hloov mus rau theem qis. Tom qab lub roj teeb yog overcharged los yog overcharged, tshem lub roj teeb ntawm lub charger thiab txuas lub load rau VDD. Thaum lub roj teeb hluav taws xob poob qis dua tus nqi tshaj, qhov sib thooj ob lub ntsuas (VD1 thiab VD4) tau pib dua, thiab cov zis Cout ua siab. Yog tias lub pob roj teeb tseem nyob hauv lub charger, txawm tias lub roj teeb voltage qis dua qhov ntsuas tus nqi dhau, kev saib xyuas tsis tuaj yeem raug zam.

DOUT tus pin yog tus pin tso zis ntawm overdischarge detector (VD2) thiab overdischarge detector (VD3). Thaum qhov hluav taws xob tso tawm qis dua qhov ntsuas hluav taws xob VDET2 ntawm lub ntsuas hluav taws xob dhau los ntawm qhov siab mus rau qis, uas yog, qis dua VDET2, DOUT tus pin poob qis tom qab qhov kev ncua ntev.

Tom qab kuaj pom kev tshaj tawm, yog tias lub charger txuas nrog lub pob roj teeb, thaum lub roj teeb muab hluav taws xob siab tshaj qhov ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob tshaj tawm, VD2 raug tso tawm thiab DOUT ua siab.

Ua-nyob rau hauv dhau-tam sim no / luv-circuit detector VD3, tom qab ib tug built-in tsau ncua, los ntawm kev hloov cov zis DOUT mus rau theem qis, qhov tso tawm dhau-tam sim no raug pom thiab qhov paug raug txiav tawm. Los yog thaum kuaj pom qhov luv luv tam sim no, DOUT tus nqi raug txo tam sim ntawd, thiab qhov tso tawm raug txiav tawm. Thaum kuaj pom qhov overcurrent lossis luv Circuit Court, lub roj teeb pob raug cais tawm ntawm qhov load, VD3 raug tso tawm, thiab DOUT qib nce.

Tsis tas li ntawd, tom qab kuaj pom qhov paug tawm, lub nti yuav ncua kev ua haujlwm ntawm lub hauv paus Circuit Court kom lub zog siv tsawg heev. Los ntawm kev teeb tsa lub davhlau ya nyob twg DS mus rau tib theem li VDD lub davhlau ya nyob twg, kev saib xyuas qeeb tuaj yeem ua kom luv (tshwj tsis yog kev saib xyuas luv luv). Tshwj xeeb, qhov kev ncua sij hawm them nyiaj ntau dhau tuaj yeem raug txo mus rau 1/90, uas txo cov sij hawm xav tau los kuaj thiab tswj xyuas lub voj voog. Thaum lub DS davhlau ya nyob twg theem tau teem nyob rau hauv ib tug tej yam ntau yam, qhov tso zis ncua sij hawm yog muab tso tseg, thiab overcharge thiab overcharge tam sim no raug kuaj pom tam sim ntawd. Lub sijhawm no, qhov ncua sijhawm yog li kaum tawm microseconds.
