Abstract
A protection device for protecting an electronic circuit against a fault is described. The electronic circuit includes an output stage for driving a load and a driving circuit for driving the output stage. The driving circuit is configured to produce a drive signal in response to at least one input signal. The protection device includes a gating circuit and control means. The gating circuit has a first input configured to receive the drive signal, a second input configured to receive a control signal, and an output configured to activate and deactivate the output stage based on the drive signal and control signal. The control means produce the control signal in response to a detection signal representative of detection of the fault either of the load or of the output stage.
