Intshayelelo yeMveliso
I-chip yeshaja yebhetri yi-chip enokuhlawula kunye nokulawula uluhlu olubanzi lweebhetri, ukusuka kwibhetri ye-lithium enye, ibhetri ye-lithium yensimbi ye-phosphate, okanye ezimbini ukuya kwezine iibhetri ze-NiMH.
Izalathisi zentsebenzo
Iimfuno eziphambili zeetshaja zanamhlanje ngamaxesha amafutshane kunye nokhuseleko (akukho monakalo kwibhetri kunye nobomi obufutshane bebhetri).Oku kufuna itshaja enesekethe edibeneyo ekwaziyo ukuqhuba imisinga ephezulu kunye nesakhono esinamandla sokubona kunye nenkqubo yokutshaja egqibeleleyo.Ngokubanzi, iitshaja ezikhawulezayo zinexesha lokutshaja elingaphantsi kweyure enye kwaye ke ngoko zifuna umsinga wokutshaja ophezulu.
Malunga neeMveliso
I-BQ25896 idityaniswe kakhulu i-3-A yokutshintsha-imowudi yolawulo lwentlawulo yebhetri kunye nesixhobo solawulo lwendlela yamandla esixhobo kwiseli enye ye-Li-Ion kunye ne-Li-polymer ibhetri.Izixhobo zixhasa igalelo lombane ophezulu wokutshaja ngokukhawuleza.Indlela yombane ephantsi yombane iphucula ukusebenza kwemowudi yokutshintsha, inciphisa ixesha lokutshaja ibhetri kwaye yandisa ubomi bebhetri ngexesha lesigaba sokukhupha.I-interface ye-I2C Serial kunye nokutshaja kunye nezicwangciso zenkqubo yenza isixhobo sibe sisisombululo esiguquguqukayo ngokwenene.
Isixhobo sixhasa uluhlu olubanzi lwemithombo yegalelo kwaye sithatha isiphumo kwisekethe yokubona kwinkqubo, njengesixhobo se-USB PHY.Igalelo langoku kunye nolawulo lolawulo lombane ukhetho luhambelana ne-USB 2.0 kunye ne-USB 3.0 yespekthi yamandla.Ukongeza, i-Input Current Optimizer (ICO) ixhasa ukufunyanwa kweendawo eziphezulu zamandla okubona umthombo wegalelo ngaphandle kokugcwala.Isixhobo sikwadibana ne-USB On-the-Go (OTG) ukulinganisa amandla okusebenza ngokunikezela nge-5 V (Adjustable 4.5V-5.5V) kwi-VBUS kunye nomda wangoku ukuya kwi-2 A.
Ulawulo lwendlela yamandla ilawula inkqubo kancinane ngaphezu kwamandla ombane webhetri kodwa ingehli ngaphantsi kwe-3.5V ubuncinane bevolthi yenkqubo (enokucwangciswa).Ngolu phawu, inkqubo igcina ukusebenza naxa ibhetri iphelelwe okanye isusiwe.Xa umyinge wegalelo langoku okanye umda we-voltage ufinyelelwe, ulawulo lwendlela yamandla lunciphisa ngokuzenzekelayo intlawulo yangoku ukuya kwi-zero.Njengoko umthwalo wenkqubo uqhubeka ukhula, indlela yamandla ikhupha ibhetri de imfuno yamandla enkqubo ifezekisiwe.
Lo msebenzi weNdlela eyoNgezelelweyo unqanda ukulayisha ngaphezulu komthombo wegalelo.
Isixhobo sikwabonelela nge-7-bit analog-to-digital converter (ADC) yokubeka iliso kwintlawulo yangoku kunye negalelo / ibhetri / inkqubo (VBUS, BAT, SYS, TS) yombane.Iphinikhodi ye-QON ibonelela nge-BATFET ukunika amandla/ukusetha kwakhona ukulawula ukuphuma kwimowudi yenqanawa yamandla aphantsi okanye inkqubo epheleleyo yokusetha kwakhona umsebenzi.
Usapho lwesixhobo lufumaneka kwi-24-pin, 4 x 4 mm2 x 0.75 mm iphakheji encinci ye-WQFN.
Imizila Yekamva
Ikamva liyathembisa kwiitshiphusi zolawulo lwamandla.Ngokuphuhliswa kweenkqubo ezintsha, ukupakishwa, kunye nobuchule boyilo lwesekethe, kuya kubakho izixhobo ezisebenza ngcono nangakumbi.Banokuphucula ukuxinana kwamandla, bandise ubomi bebhetri, banciphise ukuphazamiseka kwe-electromagnetic, baphucule amandla kunye nemfezeko yomqondiso kunye nokuphucula ukhuseleko lwenkqubo, ukunceda iinjineli kwihlabathi liphela ukuba zifezekise izinto ezintsha.
