Abstract
A self-bootstrap driving circuit includes a first input receiving a first control signal; an output, to which a load having an electro-inductive component may be connected; a power switch having first and second current terminals and a control terminal, and being arranged to drive power from a power supply terminal to the load; a bootstrap circuitry arranged to drive the control terminal of the power switch based on the control signal; and a current path between the electro-inductive component of the load and the control terminal of the switch, said current path being arranged to provide direct transfer from said electro-inductive component to said control terminal of the switch of an overvoltage generated at the electro-inductive component to provide an overdrive voltage to said control terminal of the switch.
