Abstract
A translator circuit for a drive circuit of a power transistor connected to an electric load. The translator circuit includes a first current generator placed between a supply voltage reference and an input terminal of the drive circuit, a controlled switch placed between the input terminal and a ground reference, and a second current generator interposed between the controlled switch and the ground reference. The translator circuit further includes a circuit leg in the form of a current mirror connected in parallel with the second current generator. The translator circuit avoids phenomena of false switching.
