1. A method, comprising:
coupling a power supply source to a power supply pin of a driver circuit;
coupling an electrical load to an output pin of the driver circuit;
producing, at a driver sub-circuit of the driver circuit, a driving signal for driving the electrical load;
providing the driving signal to the electrical load via the output pin;
modulating the driving signal to supply the electrical load with a load current and subsequently interrupt the load current; and
sinking from the power supply pin, at a compensation circuit of the driver circuit, a compensation current pulse in response to the load current being interrupted.
