Abstract: A high side driver component for generating a drive signal at an output thereof for driving a high side switching device within a high voltage driver circuit. The high side driver component is arranged to operate in at least one reduced slew rate mode in which at least one drive stages is arranged to be in a non-drive state, and the high side driver component further comprises at least one discharge protection component arranged to, when the high side driver component is operating in the at least one reduced slew rate mode, receive an indication of the high voltage driver circuit being in an idle state, and cause the second switching device within the at least one drive stage in a non-drive state to be turned on, in response to the indication of the high voltage driver circuit being in an idle state.

Abstract: A detection circuit for an alternator regulator, and method therefor. The detection circuit comprises an input circuit arranged to receive a phase signal from an alternator regulator and to output an attenuated sense signal representative of the received phase signal, a detection component operably coupled to the input circuit and arranged to receive the attenuated sense signal output by the input circuit, and a blocking capacitance operably coupled between the input circuit and the detection component and arranged to block a DC component of the attenuated sense signal. The detection component is arranged to compare the received attenuated sense signal to at least one reference voltage signal, and to output a signal representative of a frequency of the phase signal from the alternator regulator based at least partly on the comparison of the received attenuated sense signal to the at least one reference voltage signal.
