摘要： An electronic circuit breaker includes multiloop control loops based upon a current sensing loop and a voltage sensing loop. The current sensing loop also operates to drive a timer which ultimately controls whether current flows through the load or not. Additionally, the current loop is made to be dominant over the voltage loop. However, during normal operation the voltage loop and current loop act cooperatively to effectively control the impedance as seen by the load.

摘要： A protection circuit for a parallel power system having at least two parallel coupled voltage regulators is disclosed. The protection circuit includes at least two isolation control circuits, each control circuit being coupled to a respective voltage regulator. Each isolation control circuit includes a current sense circuit for sensing current polarity at an output of the respective voltage regulator, and a controller for automatically isolating the respective voltage regulator when an over-voltage condition exists at an output of the parallel power system and a positive current polarity is sensed at the output of the respective voltage regulator. The at least two isolation control circuits isolate only a voltage regulator having positive current outflow during the over-voltage condition. In one embodiment, each isolation control circuit further includes an over-voltage detection circuit for detecting when the over-voltage condition exists at the output of the parallel power system.

摘要： A method and apparatus for measuring the temperature on an electronic chip. The Apparatus includes a thermal sense element on the chip, a power supply passing electrical current through said thermal sense element at a known voltage and temperature, and a measuring circuit determining the initial resistance of the thermal sense element at said known voltage and temperature. The measuring circuit measures the change of the resistance of the thermal sense element as the temperature of the electronic chip changes, and compares the change in resistance of the thermal sense element to the initial resistance. The measuring circuit determines the temperature of the electronic chip from the initial resistance and change in resistance of the thermal sense element during the operation of the electronic chip.
