A power control circuit is provided for coupling a load to a power source. It includes a transistor for coupling said load to the power supply through the transistor dependent upon a control voltage applied to a control terminal of the transistor, a charge pump circuit having its output connected to the transistor control terminal to apply a controlled turn on signal to the transistor when the charge pump is activated, wherein the controlled signal gradually increases until the transistor is biased into its fully on state.
Cette invention concerne un circuit de régulation de puissance servant à coupler une charge à une source d'alimentation. Il comprend un transistor de couplage de ladite charge à ladite source en fonction d'une tension de commande appliquée à la borne de commande du transistor, un circuit de maintien de charge dont la sortie est connectée à la borne de commande du transistor pour envoyer un signal de polarisation tension contrôlé à son activation, ledit signal contrôlé augmentant graduellement d'intensité jusqu'à ce que le transistor soit totalement polarisé.
