  • Patent number: 10454469
    Abstract: An embodiment method includes detecting an inverse current condition at a switch, and driving a node associated with a switch driver driving the switch to a predetermined voltage in response to the detection of an inverse current condition at the switch. An embodiment switch device includes a switch driver configured to be coupled to a control terminal of a switch, an inverse current detector configured to detect an inverse current condition at the first and second load terminals of the switch, and a voltage driver configured to drive a node associated with the switch driver to a predetermined voltage in response to the inverse current detector detecting an inverse current condition.

  • Patent number: 7621671
    Abstract: Some embodiments discussed relate to an apparatus comprising a temperature sensor disposed in an integrated circuit, the temperature sensor including a bipolar transistor having a collector coupled to a portion of a substrate of the integrated circuit, and a bandgap reference circuit configured to generate a reference voltage, and a comparator coupled to the temperature sensor and the bandgap reference circuit, the comparator configured to receive a first voltage from the emitter of the bipolar transistor and the reference voltage from the bandgap reference circuit and generate a switch-off signal based on a voltage difference between the first voltage and the reference voltage.
