♠ LM7480-Q1 Isilawuli Se-Diode Esifanelekile Esinokuvikelwa Kokulahla Imithwalo
I-LM7480x-Q1 ekahle yesilawuli se-diode sishayela futhi silawula ama-MOSFET angaphandle abuyela emuva emuva kwe-N-Channel ukuze alingise isilungisisi se-diode esifanelekile esinendlela yamandla UKUVULA/ OFF ukulawula nokuvikela ukugcwala ngokweqile. Ukunikezwa okubanzi okokufaka okungu-3 V kuya ku-65 V kuvumela ukuvikelwa nokulawulwa kwama-ECU anamandla ebhethri lezimoto angu-12-V kanye nama-24-V. Idivayisi ingamelana futhi ivikele imithwalo kusukela kuma-voltage okunikezwayo okungalungile phansi kuya ku--65 V. Isilawuli se-diode esihle esihlanganisiwe (DGATE) sishayela i-MOSFET yokuqala ukuze imiselele i-Schottky diode yokuvikela okokufaka okuhlehlayo nokubamba i-voltage ephumayo. Nge-MOSFET yesibili endleleni yamandla idivayisi ivumela ukunqanyulwa komthwalo (ukulawula UKUVULIWA/KUVALIWE) nokuvikela ukugcwala ngokweqile kusetshenziswa isilawuli se-HGATE. Idivayisi inesici esilungisekayo sokunqanyulwa kwe-overvoltage esinqunyiwe. I-LM7480-Q1 inezinhlobonhlobo ezimbili, i-LM74800-Q1 ne-LM74801-Q1. I-LM74800-Q1 isebenzisa ukuvinjwa kwamanje okuhlanekezelwe kusetshenziswa umthethonqubo womugqa kanye nesikimu sokuqhathanisa vs. LM74801-Q1 esisekela isikimu esisekelwe kumqhanisi. Ngokucushwa kwe-Common Drain yama-MOSFET wamandla, indawo emaphakathi ingasetshenziselwa imiklamo ye-OR-ing kusetshenziswa enye i-diode efanelekile. I-LM7480x-Q1 inesilinganiso samandla kagesi esiphezulu esingu-65 V. Imithwalo ingavikelwa emigudwini eyandisiwe ye-overvoltage efana ne-200-V I-Unsuppressed Load Dumps kumasistimu webhethri angu-24-V ngokumisa idivayisi ngama-MOSFET angaphandle ku-Common Source topology.
