♠ LM7480-Q1 Woyang'anira Diode Wabwino wokhala ndi Chitetezo Chotayira Katundu
LM7480x-Q1 yabwino diode controller imayendetsa ndikuwongolera kunja kumbuyo kumbuyo kwa N-Channel MOSFETs kutsanzira chowongolera bwino cha diode chokhala ndi njira yamagetsi ON/OFF kuwongolera komanso kutetezedwa kwamphamvu.Kuyika kwakukulu kwa 3 V mpaka 65 V kumalola chitetezo ndi kuwongolera kwa 12-V ndi 24-V ma ECU oyendetsedwa ndi batire yamagalimoto.Chipangizocho chikhoza kupirira ndi kuteteza katundu kuchokera ku magetsi oyendetsa magetsi mpaka -65 V. Wolamulira wabwino kwambiri wa diode (DGATE) amayendetsa MOSFET yoyamba kuti alowe m'malo mwa Schottky diode kuti atetezedwe kumbuyo ndi kutulutsa magetsi.Ndi MOSFET yachiwiri munjira yamagetsi chipangizochi chimalola kulumikizidwa kwa katundu (ON / OFF kuwongolera) ndi chitetezo cha overvoltage pogwiritsa ntchito kuwongolera kwa HGATE.Chipangizochi chimakhala ndi chitetezo chosinthika cha overvoltage cut-off.LM7480-Q1 ili ndi mitundu iwiri, LM74800-Q1 ndi LM74801-Q1.LM74800-Q1 imagwiritsa ntchito kutsekereza kwaposachedwa pogwiritsa ntchito mzere wowongolera ndi chiwembu chofananira ndi LM74801-Q1 yomwe imathandizira chiwembu chofananira.Ndi kasinthidwe ka Common Drain ka ma MOSFET amphamvu, malo apakatikati atha kugwiritsidwa ntchito pakupanga OR-ing pogwiritsa ntchito diode ina yabwino.LM7480x-Q1 ili ndi mphamvu yamagetsi ya 65 V. Zonyamula zimatha kutetezedwa ku zowonjezereka zowonjezereka monga 200-V Unsuppressed Load Dumps mu 24-V Battery systems pokonza chipangizo ndi ma MOSFET akunja mu Common Source topology.
