Circuit arrangement for driving transistors in bridge circuits

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.
