Abstract[English]
A control driver circuit that includes a switching transistor coupled between a first voltage supply node and an output node of the gate, the output node coupled or couplable to a control node of the power transistor. A circuit includes an inductive element coupled between the control transistor and a second voltage supply node. The circuit is configured such that if the output node is coupled to the power transistor, and in response to the switching transistor being turned on, a current is induced within the inductive element and a voltage from the first voltage supply is provided to a control node of the power transistor to thereby turn on the power transistor. On the other hand, in response to the switching transistor being turned off, the induced current is drawn from the output node to thereby turn the power transistor off.[French]
La présente divulgation concerne un circuit d'attaque de commande qui comprend un transistor de commutation couplé entre un premier nœud d'alimentation en tension et un nœud de sortie de la grille, le nœud de sortie étant couplé ou pouvant être couplé à un nœud de commande du transistor de puissance. Un circuit comprend un élément inductif couplé entre le transistor de commande et un deuxième nœud d'alimentation en tension. Le circuit est configuré de telle sorte que si le nœud de sortie est couplé au transistor de puissance, et en réponse à la mise sous tension du transistor de commutation, un courant est induit à l'intérieur de l'élément inductif et une tension provenant de la première alimentation en tension est fournie à un nœud de commande du transistor de puissance pour ainsi allumer le transistor de puissance. D'autre part, en réponse à l'arrêt du transistor de commutation, le courant induit est tiré du nœud de sortie pour désactiver ainsi le transistor de puissance.
