Iimfuno zomsebenzi we-IC wokhuseleko lwebhetri yeLithium
Iimfuno zokugcina ukusebenza kweesekethe ezidibeneyo
1. Ukugcinwa kokuchaneka kwentlawulo egqithisileyo
Xa ukugqithisa, ukwenzela ukukhusela ukunyuka koxinzelelo lwangaphakathi olubangelwa ukunyuka kweqondo lokushisa, imeko yokuhlawula kufuneka imiswe. I-IC yesondlo iya kubona i-voltage yebhetri, kwaye xa i-overcharge ifunyenwe, i-overcharge ibona amandla e-MOSFEts, ebangela ukuba bavimbe kwaye bayeke ukutshaja. Okwangoku, kufuneka sinikele ingqalelo ekuchanekeni okuphezulu kombane wokubona ukutshaja. Xa utshaja ibhetri, eyona nto iphambili yomsebenzisi kukugcina ibhetri igcwele kwaye kuqwalaselwe imiba yokhuseleko. Ngoko ke, xa i-voltage evumelekileyo ifikeleleke, imeko yokutshaja kufuneka inqunyulwe. Ukudibanisa ezi meko zimbini, ii-detectors ezichanekileyo zifunekayo. Ukuchaneka kwesixhobo ngoku yi-25mV kwaye ifuna ukuphuculwa.
2. Ukunciphisa ukusetyenziswa kwamandla e-IC
Njengoko ixesha lihamba, i-voltage yebhethri ye-lithium emva kokutshaja iya kuncipha ngokuthe ngcembe ide ibe ngaphantsi kwexabiso eliqhelekileyo lenkcazo, apho ibhetri kufuneka ihlawulwe. Ukuba ibhetri iyaqhubeka isetyenziswa ngaphandle kokutshaja, isenokungasebenzi ngenxa yokuphuma okugqithisileyo. Ukuthintela ukukhutshwa okugqithisileyo kwebhetri, i-IC yolondolozo ivavanya amandla ebhetri. Xa amandla ombane ebhetri esezantsi kunombane wokubhaqa i-overdischarge, faka i-MOSFET yamandla kwicala lokukhupha ukuze uyeke ukukhupha. Nangona kunjalo, ibhetri ngokwayo isenokukhutshwa kwendalo kwaye igcina ukusetyenziswa kwe-IC ngoku, ke gcina ukusetyenziswa kwe-IC ngoku kuncinci.
3. Ukugcinwa kwe-Overcurrent / short circuit, ukufumanisa i-voltage ephantsi, ukuchaneka okuphezulu
Ukuba imbangela yesiphaluka esifutshane ayaziwa, yeka ukukhutshwa ngokukhawuleza. Ukubhaqwa kwexesha eligqithileyo kusebenzisa ii-Rds(ON) zamandla e-MOSFET njenge-impedance yokufaka esweni ukuhla kwamandla ombane. Ukuba i-voltage iphezulu kune-voltage yokufumanisa i-overcurrent, yeka ukukhutshwa. Ukuze wenze amandla e-MOSFETRds () ukutshaja okusebenzayo ngoku kunye nokukhupha isicelo sangoku, ixabiso le-impedance kufuneka libe liphantsi kangangoko kunokwenzeka, i-impedance yangoku imalunga ne-20m ~ 30m, i-voltage yangoku ingaba phantsi.
4. Ukumelana noxinzelelo oluphezulu
Xa ipakethe yebhetri iqhagamshelwe kwitshaja, i-voltage ephezulu ngokukhawuleza iyenzeka, ngoko ke i-IC yolondolozo kufuneka ihlangabezane neemfuno zokumelana nombane ophezulu.
5. Ukusetyenziswa kwamandla ebhetri aphantsi
Ngexesha lokugcinwa, usetyenziso lwamandla angatshintshiyo lwangoku luhla nge-0.1 A.
Ibhetri ye-6.0 V
Ngethuba lokugcinwa kwenkqubo, ezinye iibhetri zinokuhla kwi-0V ngenxa yexesha elide okanye izizathu ezingaqhelekanga, ngoko ke iimfuno ze-IC zokulondoloza zinokuhlawuliswa kwi-0V.
Gcina amathemba ophuhliso lweesekethe ezidibeneyo
Njengoko kukhankanyiwe ngasentla, i-IC yokugcinwa kwexesha elizayo iya kuphucula ngakumbi ukuchaneka kokufunyanwa kombane, ukunciphisa ukusetyenziswa kwamandla kwe-IC yokulondoloza, ukuphucula ukukhuselwa kwe-misoperation kunye neminye imisebenzi. Itheminali yetshaja enokumelana nombane ophezulu ikwayingqwalasela yophando kunye nophuhliso. Ngokuphathelele ukupakishwa, i-SOT23-6 iye yatshintshela ngokuthe ngcembe kwi-SON6 ukupakishwa, kwaye kuya kubakho ukupakishwa kwe-CSP kunye neemveliso ze-COB kwixesha elizayo ukuhlangabezana neemfuno zangoku zokukhanya kunye nokunciphisa.
Ukusebenza, ukugcina i-IC akufanele idibanise yonke imisebenzi. Ngokutsho kwedatha yebhetri ye-lithium eyahlukileyo, i-IC yolondolozo olulodwa inokwaziswa, njengokugcinwa kwe-overcharge okanye ukugcinwa kwe-overrelease, enokunciphisa kakhulu iindleko kunye nesikali.
Imodyuli yomsebenzi, ngokuqinisekileyo, ikristale enye yinjongo efanayo, njengabavelisi beefowuni eziphathwayo bajongene ngoku isekethe edibeneyo, isiphaluka sokutshaja kunye nolawulo lwamandla e-IC, kunye nezinye iisekethe ze-peripheral kunye ne-logic ye-IC chip zenza i-chip ezimbini, kodwa ngoku ndifuna gcina i-impedance yesekethe evulekileyo yamandla e-MOSFET, ekwindla kunye nolunye udibaniso lwe-IC, nokuba ngezakhono ezikhethekileyo kwi-chip microcomputer enye, imali nayo iphezulu kakhulu, uloyiko lwe-IBe. Ke ngoko, kuthatha ixesha ukusombulula ukugcinwa kwekristale enye ye-IC.
