Abstract: An electronic device including an electronic switch M1, an electrical pre-charge circuit and a measurement, command and diagnosis module. The main electronic switch M1 has a first electrical terminal D1, a second electrical terminal S1, and a main driving terminal G1. The main electronic switch M1 is 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 D1 is respectively connected to or disconnected from the second electrical terminal S1. 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 (V1, V2) of the first and second terminals of the device, before the main electronic switch M1 takes a closed condition, upon of a transition from the open condition.
