LM7480-Q1 Xakamaynta Diode ee ku habboon oo leh ilaalinta qashin-qubka
LM7480x-Q1 kantaroolaha diode ee ku habboon wuxuu wadaa oo koontaroolaa dibeda dib ugu noqoshada N-Channel MOSFETs si uu ugu dayo hagaajinta diode ku habboon oo leh kontoroolka ON/OFF ee korantada iyo ilaalinta korantada. Soo-gelinta ballaadhan ee 3 V ilaa 65 V waxay u oggolaanaysaa ilaalinta iyo xakamaynta 12-V iyo 24-V baytariyada baabuurta ee ECU-yada. Qalabku wuxuu u adkeysan karaa oo ka ilaalin karaa culeysyada sahayda taban ee hoos u dhacaya ilaa -65 V. Isku-darka kantaroolaha diode-ka ee isku dhafan (DGATE) wuxuu wadaa MOSFET-ka ugu horreeya si uu u beddelo diode-ka Schottky si loogu beddelo ilaalinta gelinta iyo xajinta korantada wax soo saarka. MOSFET-da labaad ee dariiqa korantada qalabku wuxuu u ogolaanayaa xidhidhiyaha rarka (ON/OFF control) iyo ilaalinta xad-dhaafka ah iyadoo la isticmaalayo xakamaynta HGATE. Qalabku waxa uu leeyahay sifa ilaalinta goynta korontadda oo la hagaajin karo. LM7480-Q1 waxay leedahay laba nooc, LM74800-Q1 iyo LM74801-Q1. LM74800-Q1 waxay shaqaaleysiisaa xannibaadda hadda jirta iyadoo la adeegsanayo nidaaminta toosan iyo nidaamka isbarbardhigga. Qaabeynta Dheecaanka Guud ee awooda MOSFETs, barta-dhexe waxaa loo isticmaali karaa naqshadaha OR-samaynta iyadoo la adeegsanayo diode kale oo ku habboon. LM7480x-Q1 waxay leedahay heerka ugu sareeya ee danab ee 65 V. Culayska waxaa laga ilaalin karaa ku-meel-gaadhka dheeraadka ah ee kor u kaca sida 200-V Qufulka Load ee 24-V ee nidaamka baytariyada iyadoo la habeynayo qalabka MOSFETs dibadda ah ee Topology Source .
