  • Patent number: 11206016
    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.

  • Patent number: 11171559
    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.

  • Patent number: 10651894
    Abstract: A transceiver capable of common mode operating range and output voltage tolerance set by an isolation boundary and not limited by the device type used in the circuitry. The subject technology is a powered isolated transceiver, where the isolated generated supply and ground nodes are concealed and thus do not participate in tests that stress electrostatic discharge (ESD)/electrical overstress (EOS) or voltage tolerance. The architecture of the subject technology has the advantage of extremely high common mode performance and robust performance using low voltage devices and simplified architecture, which in turn provides less capacitive loading, faster operation, less expensive die development, electromagnetic interference (EMI) advantages, and simple active termination. The subject technology includes an isolation architecture that can be used in environments where isolation is used but is also advantageous in systems without the need for isolation.
