Abstract: An electronic circuit comprises a power switch and a fault detection circuit. The power switch circuit includes a power switch transistor. The fault detection circuit includes a comparator circuit configured to monitor a voltage across the power switch transistor and compare the voltage to a varying threshold voltage that decreases with time, and produce an indication of a circuit fault when the voltage of the power switch transistor is greater than the time varying threshold voltage.

Abstract: A switched power circuit to control a common-mode signal. The switched power circuit includes a first switch and a second switch configured to generate switch mode voltage between a first node and a second node. The switched power circuit further includes a feedback circuit that is configured to detect common-mode voltage generated between the first node and the second node by a first signal generated by the first switch and a second signal generated by the second switch, and incrementally adjust a timing parameter of the first signal to adjust the common-mode signal.

Abstract: A circuit to control a switching characteristic of a switching device. The circuit includes a driver circuit comprising an output port, where the driver circuit is configured to generate, at the output port, a control signal to actuate the switching device within a first time period. The control signal comprising at least one electrical pulse, where a pulse width of the at least one electrical pulse being shorter than the first time period. The circuit also includes a coupling circuit that is configured to use the control signal to actuate the switching device to establish a target switching characteristic of the switching device according to a modulation of the at least one electrical pulse. The control circuit is also configured to provide a greater impedance to the control signal than an impedance of the output terminal of the driver circuit.
