The electronic circuit includes a transistor having a gate terminal, a source terminal and a drain terminal. A resistor has a first terminal connected to the gate terminal and has a second terminal connected to an auxiliary pad. When the electronic circuit is operating in a test phase and is configured for receiving a test signal for performing the test of the transistor, the auxiliary pad is electrically floating. When the electronic circuit is operating in a normal phase and is configured for receiving a supply voltage, the auxiliary pad is electrically connected to a voltage value smaller than the sum of the voltage value of the source terminal with the threshold voltage value of the transistor.

Electronic circuit and method for testing and keeping a MOS transistor switched-off

An electronic circuit includes a node coupled to a load to be driven, and a power device, which can be switched between activation and deactivation and coupled to the node. The circuit further includes a current generator having an output connected to the node and that can be enabled to generate current at least when the power device is deactivated. The circuit also includes a comparator for comparing an electric voltage of the node with a reference voltage and is configured to generate a comparison signal based thereon.
