Abstract: A driver circuit is configured to control a power transistor. The driver circuit comprises a signal generator configured to generate a control signal for the power transistor based on a supply signal and an input signal from a control unit. In addition, the driver circuit includes a ripple detector configured to receive the supply signal and determine whether the supply signal includes a ripple error. In some examples, the ripple detector may be configured to send a warning signal to the control unit in response to detecting the ripple error.

Abstract: A driver circuit is configured to deliver drive signals from an output pin to a power switch to control ON/OFF switching of the power switch. A first detection pin of the driver circuit is configured to receive a first signal associated with the power switch, wherein the first signal indicates a voltage drop over the power switch and a voltage drop over one or more other circuit elements. A second detection pin is configured to receive a second signal, wherein the second signal indicates a voltage drop over one or more matched circuit elements, wherein the one or more matched circuit elements associated with the second signal are substantially identical to the one or more other circuit elements associated with the first signal. The driver circuit is configured to determine the voltage drop over the power switch based on a difference between the first signal and the second signal.

Abstract: An example a circuit for controlling a power converter comprises a first power domain circuit including a first control circuit and a first driver circuit, wherein the first control circuit controls the first driver circuit to drive a first semiconductor device, wherein a second power domain circuit includes a second control circuit and a second driver circuit. The first control circuit is configured to receive a control signal for controlling the second driver circuit to drive a second semiconductor device; and identify, based on the control signal, a future electrical characteristic of a second power domain output of the power converter. Additionally, the first control circuit is configured to determine, based on the future electrical characteristic of the second power domain output of the power converter, whether to adjust one or more control parameters for controlling the first driver circuit to drive the first semiconductor device.
