Abstract: In one example, an apparatus comprises: a voltage sensing circuit having a voltage sensing terminal and a voltage sensing output, the voltage sensing circuit configured to generate a first voltage at the voltage sensing output representing a second voltage at the voltage sensing terminal; a control circuit having a control circuit input and a control circuit output, the control circuit input coupled to the voltage sensing output, the control circuit configured to: determine a state of a transistor based on the first voltage; and generate a driver signal at the control circuit output based on the state; and a driver circuit having a driver input and a switch control output, the driver input coupled to the control circuit output, the driver circuit configured to provide a current at the switch control output responsive to the driver signal.
