Abstract
A driver circuit comprises a first transistor coupled to a second transistor, and a third transistor coupled to the first and second transistor and to a first current mirror. An output of the first current mirror is provided to a control input of the second transistor. A second current mirror is coupled to the output of the first current mirror. A first current source, a second current source, and a fourth transistor are coupled to the second current mirror. The second current source is further coupled to a fifth transistor. A sixth transistor is coupled to the fifth transistor and to a third current mirror. In some implementations, the driver circuit is coupled to a low side transistor in an H bridge driver and the second transistor is matched to the low side transistor.
