Abstract
A circuit arrangement includes a half-bridge with a high-side switch and a low-side switch, each switch including a control terminal and a load path. The load paths of the high-side switch and the low-side switch are coupled in series between a terminal for a supply potential and a terminal for a reference potential a high-side driver operable to provide a high-side drive signal received at the control terminal of the high-side switch. The high-side driver includes supply terminals a charge storage device coupled between the supply terminals of the high-side driver. A control circuit includes a charging circuit, a switching element and a drive circuit operable to switch on the switching element dependent on at least one operation parameter of the circuit arrangement.
