Incazelo evamile
I-MAX8969 iyisiguquli esilula se-1A esikhuphukela phezulu kuphakheji encane esebenza kunoma yiluphi uhlelo lwe-Li-ion yeseli elilodwa.Le IC inikeza izici zokuvikela ezifana nokuvala iminyaka yobudala ye-undervolt, i-short circuit, nokuvalwa kwezinga lokushisa elingaphezulu.Izinguquko ze-IC zeqe imodi kalula ngaphansi kwezimo zokulayisha ukukhanya ukuze kuthuthukiswe ukusebenza kahle.Ngaphansi kwalezi zimo, ukushintsha kwenzeka kuphela njengoba kudingeka, kunciphisa imvamisa yokushintsha kanye nokunikezela kwamanje ukuze kugcinwe ukusebenza kahle okuphezulu.Ukuze uthole ukusebenza kahle okuphezulu lapho i-voltage yokufaka iseduze ne-voltage ephumayo, izindlela ezimbili ezikhethekile zokusebenza ziyatholakala: ithrekhi ne-othomathikhi.Lezi zindlela zivumela abasebenzisi ukuthi balinganisele i-quiescent current (IQ) ngokumelene nesikhathi sokuphendula sesikhashana baye kumodi yokuthuthukisa.Kuzo zombili izindlela, i-p-channel MOSFET isebenza njengokushintshwa okunomkhawulo wamanje ngendlela yokuthi i-VOUT ilandele i-VIN.Kodwa-ke, kumodi yethrekhi, i-boost circuits ivaliwe futhi isistimu ilawula umsebenzi we-boost nge-EN, okokufaka kwe-TREN (IQ = 30µA).Kumodi yethrekhi ezenzakalelayo (ATM), amasekhethi e-boost anikwa amandla futhi idivayisi ishintshela ngokuzenzakalela kumodi ye-boost lapho i-VIN iwela ku-95% we-VOUT eqondiwe (IQ = 60µA).I-IC itholakala ngencanyana, 1.25mm x 1.25mm , iphakheji ye-WLP engu-9-bump (0.4mm pitch).
