♠ LM7480-Q1 Ideal Diode Controller e nang le Tšireletso ea ho Lahlela Moroalo
LM7480x-Q1 selaoli se loketseng sa diode se khanna le ho laola li-MOSFET tsa N-Channel tse ka morao ho etsisa mochini o lokiselitsoeng hantle oa diode ka tsela ea matla ON/OFF le ts'ireletso ea overvoltage. Phano e pharalletseng ea 3 V ho isa ho 65 V e lumella ts'ireletso le taolo ea 12-V le 24-V ea li-ECU tsa likoloi tsa likoloi. Sesebelisoa se ka mamella le ho sireletsa mejaro ho tloha ho li-voltage tse mpe ho fihlela ho -65 V. Sesebelisoa se kopantsoeng sa diode controller (DGATE) se khanna MOSFET ea pele ho nkela sebaka sa Schottky diode bakeng sa ts'ireletso e khutlisetsang morao le ho ts'oaroa ha motlakase. Ka MOSFET ea bobeli tseleng ea matla sesebelisoa se lumella ho khaola mojaro (taolo ea ON / OFF) le ts'ireletso ea overvoltage e sebelisang taolo ea HGATE. Sesebelisoa se na le ts'ireletso e feto-fetohang ea overvoltage cut-off. LM7480-Q1 e na le mefuta e 'meli, LM74800-Q1 le LM74801-Q1. LM74800-Q1 e sebelisa thibelo ea morao-rao ea morao-rao e sebelisa melao ea tsamaiso le mokhoa oa ho bapisa vs. LM74801-Q1 e tšehetsang morero o thehiloeng ho bapisa. Ka tlhophiso e tloaelehileng ea Drain ea li-MOSFET tsa matla, sebaka se bohareng se ka sebelisoa bakeng sa meralo ea OR-ing ho sebelisoa diode e 'ngoe e loketseng. LM7480x-Q1 e na le tekanyo e phahameng ea voltage ea 65 V. Meroalo e ka sireletsoa ho tloha ho overvoltage transients e atolositsoeng joaloka 200-V Unsuppressed Load Dumps in 24-V Battery systems ka ho lokisa sesebelisoa ka MOSFET e ka ntle ho Common Source topology.
