High power output stage with temperature stable precisely controlled quiescent current and inherent short circuit protection |
摘要 |
An output stage driver circuit comprising two parallel class AB stages running at slightly different quiescent currents, the difference of which is scaled up through a current mirror is disclosed which provides a temperature stable precisely controlled quiescent current for the output stage. A current limited voltage source is provided to ensure inherent short circuit protection with instantaneous response to short circuit or excessive load current conditions.
