Abstract
A method and apparatus for driving a power stage is presented. In particular, the power stage is a half-bridge. In the method, there is a first power switch coupled to a second power switch via a switching node. The method steps include sensing a first control-terminal voltage of one of the first power switch and the second power switch and turning on the first power switch based on the first control-terminal voltage and sensing a second control-terminal voltage of one of the first power switch and the second power switch and turning on the second power switch based on the second control-terminal voltage. Optionally, the first power switch is turned on when the first control-terminal voltage has reached a first threshold value, and the second power switch is turned on when the second control-terminal voltage has reached a second threshold value.
