An output MOS transistor has a drain connected with a power supply and a source connected with an output terminal. The short-circuit MOS transistor has a source connected with the output terminal. The short-circuit MOS transistor is formed in a semiconductor substrate connected with the power supply. A switching device is formed in a semiconductor region which is formed in the semiconductor substrate, and contains a first diffusion layer connected with the gate of the output MOS transistor and a second diffusion layer formed in the semiconductor region and connected with the drain of the short-circuit MOS transistor.

A method of regulating a motor, including monitoring an absolute voltage value across an anode and a cathode of a triode via an analog switching circuit, the triode being configured to facilitate power a motor, activating a gate of the triode via the circuit in response to the absolute voltage value being greater than a predetermined threshold, and deactivating the gate of the triode via a switching circuit in response to the absolute voltage value being less than the predetermined threshold.

A power electronics device includes a voltage-driven transistor, a galvanically isolated gate driver and an energy storage device.
