Abstract: A microelectronic device has a common terminal transistor with two or more channels, and sense transistors in corresponding areas of the channels. The channels and the sense transistors share a common node in a semiconductor substrate. The sense transistors are configured to provide sense currents that are representative of currents through the corresponding channels. The sense transistors are located so that a ratio of the channel currents to the corresponding sense currents is less than a target value of cross-talk. The microelectronic device may be implemented without a compensation circuit which provides a compensation signal used to adjust one or more of the sense currents to reduce cross-talk. A method of forming the microelectronic device, including estimating a potential distribution in the semiconductor substrate containing the common node of the common terminal transistor, and selecting locations for the sense transistors based on the estimated potential distribution, is disclosed.

Abstract: A circuit protective system. The system includes an output controlling enablement of a transistor and an input sensing an operational parameter associated with the transistor. The system also includes detection circuitry providing an event fault indicator if the operational parameter violates a condition. The system also includes protective circuitry disabling the transistor in response to the event fault indicator and subsequently selectively applying an enabling bias to the transistor; the enabling bias is selected from at least two different bias levels and in response to a number of event fault indications from the detection circuitry.

Abstract: Methods, apparatus, systems, and articles of manufacture providing adaptive voltage clamps are disclosed. An example apparatus includes a voltage clamp to clamp a drain-to-source voltage of a transistor to a first voltage when the drain-to-source voltage exceeds the first voltage, and a controller to generate a control signal to direct the voltage clamp to clamp the drain-to-source voltage to a second voltage different from the first voltage based on a fault signal.

Abstract: A circuit protective system with an input for sensing a reference current and an input for sensing a reference voltage. The system also has circuitry for determining an estimated energy in response to the reference current and the reference voltage and circuitry for generating a control signal responsive to the estimated energy exceeding a threshold.

Abstract: A circuit protective system. The system has: (i) an input for sensing an operational voltage responsive to a current flowing through a transistor; (ii) circuitry for applying a forced voltage at the input; (iii) voltage-to-current conversion circuitry for outputting a reference current in response to the forced voltage at the input; (iv) circuitry for providing a reference trim current in response to a trim indicator; and (v) comparison circuitry for outputting a limit signal in response to a comparison of the reference current and the reference trim current.
