A half-bridge electronic device comprises, in series, a low level switch and a high level switch connected at a central point, and respectively controlled by a first and a second activation/deactivation signal. The device comprises: a first and a second synchronization system configured to interpret a variation in the voltage at the central point, respectively along a falling edge and along a rising edge, and to respectively generate a first and a second synchronization signal separate from the first; a first and a second AND type logic gate respectively combining the first synchronization signal with a first control signal and the second synchronization signal with a second control signal, in order to respectively form the first and second activation/deactivation signals.
