Disponible en bo&icirc;tier compact SO-8, ce circuit tampon int&eacute;gr&eacute; remplace jusqu&rsquo;&agrave; dix composants discrets pour un montage syst&egrave;me plus simple, compact et robuste.<br \/>\nLes tr&egrave;s faibles imp&eacute;dances de sortie et pertes de puissance de ce circuit rendent possible son utilisation dans des environnements difficiles et sous haute temp&eacute;rature. En outre, il peut commander une tension Vgs n&eacute;gative et rester &agrave; l&rsquo;&eacute;tat passant en continu gr&acirc;ce &agrave; la sortie PMos int&eacute;gr&eacute;e en parall&egrave;le de la sortie NMos de tirage (pull-up) c&ocirc;t&eacute; haut. Les sorties s&eacute;par&eacute;es OUTH et OUTL permettent de s&eacute;lectionner deux r&eacute;sistances externes diff&eacute;rentes pour charger et d&eacute;charger la grille, afin de mieux contr&ocirc;ler les &eacute;missions &eacute;lectromagn&eacute;tiques (EMI) et l&rsquo;effet CdV\/dT dans les applications SMPS et de commande de moteur &agrave; puissance &eacute;lev&eacute;e.<br \/>\nConforme aux standards AEC-Q100, ce circuit est encapsul&eacute; dans un bo&icirc;tier classique SO-8 employant des mat&eacute;riaux respectueux de l&rsquo;environnement, sans plomb et conformes RoHS. Il s&rsquo;inscrit dans le cadre de l&rsquo;initiative qualit&eacute; automobile d&rsquo;IR visant le z&eacute;ro d&eacute;faut.<\/p>\n<\/p>\n<p><a target=\"_blank\" href=\"http:\/\/www.irf.com\/\"
