    摘要: 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.

    摘要: 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 a High Electron Mobility Transistor.

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.

    摘要: 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.
