Idayagram yolawulo lokutshaja olulula lwesekethe yebhetri ye-lithium-ion

Njengoko kubonisiwe kumzobo yisekethe yolawulo lokutshaja ibhetri ye-lithium.

Ikakhulu yenziwe yi-lithium ibhetri yokutshaja i-chip TP4056 kunye nezixhobo zangaphandle ezidityanisiweyo.

I-TP4056 yitshiphu ephuhliselwe i-single-cell lithium ibhetri yokutshaja kunye nolawulo. Ifuna kuphela amacandelo ambalwa angaphandle ahlukeneyo ukwakha kunye nokugqibezela. Ke ngoko, isoloko isenziwa ngokuthe ngqo kwiimodyuli ze-elektroniki ezithengiswa ngabasasazi abakhulu be-elektroniki, eququzelela kakhulu ii-elektroniki ezahlukeneyo ezisetyenziswa ngabathandi.

Intshayelelo kwi-TP4056

I-TP4056 yibhetri ye-lithium-ion epheleleyo yeseli enye ene-stable current/stable voltage linear charger. Iphakheji ye-SOP8 ene-heat sink ezantsi kunye nenani elincinci lamalungu angaphandle lenza i-TP4056 ibe yinto efanelekileyo yokusetyenziswa okuphathekayo. I-TP4056 inokulungela unikezelo lwamandla e-USB kunye nokusebenza kombane weadaptha.

Ngenxa yoyilo lwangaphakathi lwe-PMOSFET kunye ne-anti-reverse charging circuit, akukho diode yokuthintela yangaphandle efunekayo. Impendulo ye-thermal inokulungelelanisa ngokusebenzayo ukutshaja kwangoku ukunyanzelisa ubushushu be-chip phantsi kokusebenza kwamandla aphezulu okanye iimeko zokushisa eziphezulu. I-voltage yokutshaja igxininiswe kwi-4.2V, kwaye umbane wokutshaja unokusetwa ngaphandle ngaphandle kwe-resistor. Xa ukutshaja kwangoku kuhla ukuya kwi-1/10 yexabiso elimiselweyo emva kokufikelela kumbane wokugqibela we-float, i-TP4056 iya kumisa ngokusebenzayo umjikelo wokutshaja.

Xa i-voltage yegalelo (i-adapter yonxibelelwano okanye unikezelo lwamandla e-USB) isusiwe, i-TP4056 ingena ngenkuthalo kwimeko ephantsi yangoku, inciphisa ukuvuza kwebhetri yangoku ukuya ngaphantsi kwe-2uA. I-TP4056 inokuphinda ibekwe kwimowudi yokuvala xa kukho unikezelo lwamandla, ukuze kuncitshiswe unikezelo lwangoku ukuya kwi-55uA. Ezinye iimpawu ze-TP4056 ziquka ukubonwa kobushushu bebhetri, ukuvalwa kwe-voltage, ukutshaja okusebenzayo kunye nezikhonkwane ezimbini ze-LED ukubonisa ukutshaja kunye nokugqitywa.
