A circuit includes an input terminal and a regulated supply line for supplying an electronic device with an electrostatic discharge protection and driver circuit for the electronic device. The supply line is coupled to the input terminal via the circuitry, so that current injected into the input terminal may produce a voltage increase on the regulated supply line. A comparator sensitive to the voltage at the input terminal and the voltage on the supply line is provided. A current sink coupled with the supply line and being activatable to sink current from the supply line is also provided. The comparator is configured for activating the current sink as a result of the voltage at the input terminal exceeding the voltage on the supply line of a certain intervention threshold.
