Des avanc\u00e9es rapides dans l\u2019ADAS et dans la conduite automatis\u00e9e pour le secteur automobile ont stimul\u00e9 la demande pour des fonctions telles que la pr\u00e9vention des collisions et l\u2019assistance au changement de voie qui r\u00e9duisent le risque d\u2019accidents. Par cons\u00e9quent, le d\u00e9veloppement de produits pour les semiconducteurs doit prendre en compte la fa\u00e7on d\u2019assurer la s\u00e9curit\u00e9 fonctionnelle (s\u00e9curit\u00e9 intrins\u00e8que) en cas de panne tout en consid\u00e9rant l\u2019autodiagnostic et d\u2019autres fonctions sp\u00e9cifiques.
\nEn 2017, ROHM a d\u00e9velopp\u00e9 un jeu de composants LCD prenant en charge la s\u00e9curit\u00e9 fonctionnelle et se composant de drivers LCD et de circuits int\u00e9gr\u00e9s d\u2019alimentation \u00e9lectrique en avance sur l\u2019industrie. En 2018, la soci\u00e9t\u00e9 a obtenu la certification du processus de d\u00e9veloppement en vertu de la norme internationale de d\u00e9veloppement de la s\u00e9curit\u00e9 fonctionnelle ISO26262. \u00c0 cette \u00e9poque, en ce qui concerne la s\u00e9curit\u00e9 et la redondance des syst\u00e8mes, ROHM a cr\u00e9\u00e9 le premier circuit int\u00e9gr\u00e9 de surveillance de l\u2019alimentation \u00e9lectrique de l\u2019industrie avec fonction d\u2019autodiagnostic int\u00e9gr\u00e9e qui permet d\u2019ajouter facilement la s\u00e9curit\u00e9 fonctionnelle aux syst\u00e8mes existants.
\nLe BD39040MUF-C est un circuit int\u00e9gr\u00e9 de surveillance de puissance qui assure les fonctions de surveillance n\u00e9cessaires \u00e0 la s\u00e9curit\u00e9 fonctionnelle des syst\u00e8mes d\u2019alimentation \u00e9lectrique des modules de capteurs ADAS. En plus des fonctions de surveillance de tension (Power Good & reset) et d\u2019un Watchdog pour surveiller l\u2019ECU indispensable \u00e0 la s\u00e9curit\u00e9 fonctionnelle, le circuit int\u00e9gr\u00e9 de surveillance de l\u2019alimentation \u00e9lectrique de ROHM est le premier dans l\u2019industrie \u00e0 introduire une fonction d\u2019autodiagnostic. En utilisant une technologie originale, ce circuit int\u00e9gr\u00e9 permet de d\u00e9tecter la d\u00e9faillance potentielle du circuit int\u00e9gr\u00e9 d\u2019alimentation lui-m\u00eame sans affecter les syst\u00e8mes existants. L\u2019int\u00e9gration de ces fonctions dans un bo\u00eetier compact de 3 mm carr\u00e9 le rend id\u00e9al pour les applications ADAS exigeant une miniaturisation \u00e0 un degr\u00e9 pouss\u00e9.<\/p>\n
