Patent ID: 8558586

Claim:
A circuit arrangement comprising: a half-bridge with a high-side switch and a low-side switch, each switch comprising a control terminal and a load path, the load paths of the high-side switch and the low-side switch 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 comprising supply terminals; a charge storage device coupled between the supply terminals of the high-side driver; and a control circuit comprising: a charging circuit with an input terminal coupled to a supply terminal and having an output terminal for providing an output voltage, a switching element coupled between the output terminal of the charging circuit and the charge storage device, and a drive circuit operable to switch on the switching element dependent on at least one operation parameter of the circuit arrangement.
