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.
