Abstract
An electronic device including an electronic switch M, an electrical pre-charge circuit and a measurement, command and diagnosis module. The main electronic switch Mhas a first electrical terminal D, a second electrical terminal S, and a main driving terminal G. The main electronic switch Mis adapted to take, based on a driving signal DRV, depending on the command signal CMD and on an enabling signal ENB, a closed condition or an open condition, wherein the first electrical terminal Dis respectively connected to or disconnected from the second electrical terminal S. The pre-charge electrical circuit is adapted to carry out, based on the command signal CMD, a pre-charge operation, aimed at equalizing the electric potentials (V, V) of the first and second terminals of the device, before the main electronic switch Mtakes a closed condition, upon of a transition from the open condition.
