    • An over-current protection circuit, including a current input for receiving a input current and a current output electrically connectable to a load, for outputting an output current proportional to the input current. A switch connects the current input to the current output. The switch has at least two switch states including an open state in which a current flow from the current input to the current output is interrupted and a closed state in which the current flow is enabled. The switch includes a switch control input for controlling the switch state. The circuit has a sensor for sensing a load current applied to the load and a controller connected to the sensor for controlling the switch to be in the open state when the sensed load current has exceeded a current threshold during a predetermined period of time, the predetermined period of time being dependent on an amount with which said sensed load current exceeds the threshold.

    • An over-current protection circuit including, a current supply switch with a first terminal coupled to a supply current input and with a second terminal coupled to a supply current output. The current supply switch is switchable at least between an on-state, in which the current supply switch provides a conductive connection between the first terminal and the second terminal, and an off-state, in which the current supply switch interrupts the conductive connection between the first terminal and the second terminal. The over-current protection circuit receives a supply current via the supply current input and provides the supply current via the supply current output if the switch is in the on-state. The current supply switch includes High Electron Mobility Transistor.

    • An integrated circuit comprises a power device located on a die. The power device is operably coupled to a processing function, wherein the signal processing function is operably coupled to two or more temperature sensors. A first temperature sensor is operably coupled to the power device to measure a temperature of the power device and the second temperature sensor is located, such that it measures a substantially ambient temperature related to the die. The signal processing function determines the temperature gradient therebetween.In this manner, improved reliability of the integrated circuit and power device is obtained, as the power device utilises the fact that its thermo-mechanical stress reliability strongly depends upon the temperature gradient across the die rather than the number of times it reaches an excessive temperature.
    • 集成电路包括位于管芯上的功率器件。 功率器件可操作地耦合到处理功能,其中信号处理功能可操作地耦合到两个或更多个温度传感器。 第一温度传感器可操作地耦合到功率器件以测量功率器件的温度,并且第二温度传感器被定位,使得其测量与管芯相关的基本环境温度。 信号处理功能确定其间的温度梯度。 以这种方式,获得了集成电路和功率器件的可靠性的提高,因为功率器件利用其热机械应力可靠性强烈地取决于晶片上的温度梯度而不是达到过高温度的事实 。
