Abstract

La présente invention concerne un dispositif de sortie de commande logique pour calculateur, présentant une faible tension de déchet. Le dispositif de sortie de commande logique pour calculateur selon l'invention, susceptible d'être intégré à un composant configuré de telle sorte que plusieurs dispositifs de sortie de commande logique commandent une même charge (CH), et comprenant un premier transistor (T1,T2), comporte par ailleurs un second transistor (T10,T20) monté tête-bêche par rapport au premier transistor (T1,T2), configuré pour assurer la fonction de diode de puissance, et associé à au moins deux diodes de faible puissance (D1,D2,D1',D2') et à au moins une résistance (R,R')visant à empêcher des mauvais fonctionnements du dispositif.The present invention relates to a logic control output device for a computer, having a low dropout voltage. The logic control output device for a computer according to the invention, capable of being integrated into a component configured such that several logic control output devices control the same load (CH), and comprising a first transistor (T1, T2), furthermore comprises a second transistor (T10, T20) mounted head-to-tail with respect to the first transistor (T1, T2), configured to perform the function of a power diode, and associated with at least two low power diodes ( D1, D2, D1 ', D2') and at least one resistor (R, R ') aimed at preventing malfunctions of the device.
