  • Patent number: 10499547
    Abstract: A thermal control process for an electronic power device including a multi junction integrated circuit may include defining a first and at least one second groups of junctions, with each group including one first and at least one second junctions, and associating a thermal detector with each group. A first group control may be executed which detects group electric signals representative of the temperature detected by the thermal detectors, processes the group electric signals with reference to a group critical thermal event, identifies a critical group when the corresponding group electric signal detects the critical group thermal event, and generates group deactivating signals suitable for selectively deactivating the first and the at least one second junctions of the identified critical group with respect to the remaining junctions of the integrated circuit.

The amplifying circuit has a control input for controlling a supply current flow to the electrochrome element, a feedback input, and an output. The variable resistor element has a first resistor terminal, a second resistor terminal coupled to the feedback input and a resistor control terminal for controlling a resistance of the variable resistor element. The resistor control terminal is coupled to the amplifying circuit output, the first resistor terminal is coupleable to a power source, and the second resistor terminal is coupleable to the electrochrome element such that a supply current path to the electrochrome element through the variable resistor element is formed. The capacitor is coupled to the resistor control terminal for effecting a stable behavior of the supply current flow to the electrochrome element.

  • Patent number: 6255892
    Abstract: The temperature sensor measures temperatures within a defined temperature measuring range. The sensor includes a reference voltage source with an output terminal to which a reference voltage is applied and which is connected to a first input terminal of a comparator. A series circuit of a semiconductor component with temperature-independent current characteristic and a reference component is connected between a first and a second supply voltage terminal. A temperature-dependent voltage is applied to a node common to the semiconductor component and the reference component. The temperature-dependent voltage is fed to a second input terminal of the comparator. The supply voltage is adjustable within a defined supply voltage range and, within a voltage range resulting from the supply voltage range of a voltage across the reference component, the reference component has a voltage-dependent current characteristic.
