♠ LM7480-Q1 Isilawuli seDiode esiLungileyo kunye noKhuseleko lokuLahlwa koMthwalo
I-LM7480x-Q1 isilawuli esifanelekileyo se-diode siqhuba kwaye silawula ngaphandle ngasemva ngasemva kwi-N-Channel MOSFETs ukulinganisa i-diode rectifier efanelekileyo kunye nendlela yamandla ON / OFF ulawulo kunye nokukhusela ukugqithisa. Ukunikezelwa kwegalelo elibanzi kwi-3 V ukuya kwi-65 V ivumela ukukhuselwa kunye nokulawulwa kwe-12-V kunye ne-24-V ye-automotive battery powered ECUs. Isixhobo sinokumelana kunye nokukhusela imithwalo evela kumbane wonikezelo olubi ukuya kuthi ga kwi -65 V. Isilawuli se-diode esidibeneyo esidibeneyo (i-DGATE) siqhuba i-MOSFET yokuqala ukuba ithathe indawo ye-Schottky diode yokukhusela igalelo lokubuyela umva kunye ne-voltage holdup. Nge-MOSFET yesibini kwindlela yamandla isixhobo sivumela ukuqhawula umthwalo (ON / OFF ulawulo) kunye nokukhuselwa kwe-overvoltage usebenzisa ulawulo lwe-HGATE. Isixhobo sibonisa i-adjustable overvoltage cut-off protection feature. I-LM7480-Q1 ineenguqu ezimbini, i-LM74800-Q1 kunye ne-LM74801-Q1. I-LM74800-Q1 isebenzisa ukuvinjelwa kwangoku ngokubuyisela umva usebenzisa umgaqo womgca kunye neskimu sokuthelekisa kunye ne-LM74801-Q1 exhasa iskimu esisekelwe kumlinganisi. Ngolungelelwaniso lwe-Common Drin yamandla e-MOSFETs, indawo ephakathi inokusetyenziselwa uyilo lwe-OR-ing kusetyenziswa enye idiode efanelekileyo. I-LM7480x-Q1 inomlinganiselo ophezulu we-voltage ye-65 V. Imithwalo inokukhuselwa kwi-overvoltage transients eyandisiweyo njenge-200-V ye-Unsuppressed Load Dumps kwiinkqubo ze-Battery ze-24-V ngokuqwalasela isixhobo kunye ne-MOSFET yangaphandle kwi-Common Source topology.
