Abstract
A driver circuit includes a first switch which has a first terminal coupled to a voltage supply terminal, a second terminal coupled to a high-side gate, and a third terminal coupled to receive a voltage supply enable signal. The first switch is operable to connect the voltage supply terminal to the high-side gate responsive to the voltage supply enable signal. The driver circuit includes a second switch which has a first terminal coupled to a charge pump terminal, a second terminal coupled to the high side gate, and a third terminal coupled to receive a charge pump enable signal. The second switch is operable to connect the charge pump terminal to the high-side gate responsive to the charge pump enable signal.
