  • Patent number: 11916544
    Abstract: A method for driving a power transistor includes comparing a measurement signal that is representative of a load current to a comparator threshold that corresponds to an overcurrent threshold; generating a first fault signal when the measurement signal exceeds the comparator threshold for a first time interval; generating a second fault signal when the measurement signal exceeds the comparator threshold for a second time interval that is greater than the first time interval; regulating a control voltage provided to the control terminal of the transistor to turn off the transistor in response to the second fault signal; and in response to the first fault signal, adjusting the control voltage to an adjusted voltage level in order to limit the load current to a reduced current level that is preconfigured to be greater than the overcurrent threshold. The adjusted voltage level is sufficient to maintain the power transistor in an on-state.

  • Patent number: 11908694
    Abstract: In an example, a substrate is oriented to a target axis, wherein a residual angular misalignment between the target axis and a preselected crystal channel direction in the substrate is within an angular tolerance interval. Dopant ions are implanted into the substrate using an ion beam that propagates along an ion beam axis. The dopant ions are implanted at implant angles between the ion beam axis and the target axis. The implant angles are within an implant angle range. A channel acceptance width is effective for the preselected crystal channel direction. The implant angle range is greater than 80% of a sum of the channel acceptance width and twofold the angular tolerance interval. The implant angle range is smaller than 500% of the sum of the channel acceptance width and twofold the angular tolerance interval.
