♠ LM7480-Q1 Ideal Diode Controller tare da Kariyar Juji
LM7480x-Q1 manufa mai sarrafa diode mai sarrafawa da sarrafa waje na baya zuwa baya N-Channel MOSFETs don yin koyi da ingantaccen mai gyara diode tare da ikon ON / KASHE hanyar wutar lantarki da kariya ta wuce gona da iri. Faɗin shigarwar 3 V zuwa 65 V yana ba da damar kariya da sarrafa 12-V da 24-V na baturi mai ƙarfi na ECUs. Na'urar zata iya jurewa da kuma kare kaya daga madaidaitan ƙarfin samar da wutar lantarki zuwa -65 V. Ƙwararren mai kula da diode mai mahimmanci (DGATE) yana fitar da MOSFET na farko don maye gurbin Schottky diode don mayar da kariya ta shigarwa da kuma riƙewar wutar lantarki. Tare da MOSFET na biyu a cikin hanyar wutar lantarki na'urar tana ba da damar cire haɗin kaya (ikon ON/KASHE) da kariya ta wuce gona da iri ta amfani da sarrafa HGATE. Na'urar tana da fasalin kariyar da za a iya daidaitawa na yanke kashe wuta. LM7480-Q1 yana da bambance-bambancen guda biyu, LM74800-Q1 da LM74801-Q1. LM74800-Q1 yana amfani da toshewar baya na yanzu ta amfani da tsarin layi da tsarin kwatancen vs. LM74801-Q1 wanda ke goyan bayan tsarin tushen kwatance. Tare da Tsarin Ruwa na gama gari na MOSFETs mai ƙarfi, ana iya amfani da tsakiyar maƙasudi don ƙirar OR-ing ta amfani da wani ingantaccen diode. LM7480x-Q1 yana da matsakaicin ƙimar ƙarfin lantarki na 65 V. Za'a iya kiyaye nauyin kaya daga wuce gona da iri kamar 200-V Unsuppressed Load Dumps a cikin tsarin baturi na 24-V ta hanyar daidaita na'urar tare da MOSFET na waje a cikin Topology na Gaba ɗaya.
