A protection circuit detects short circuit and/or current overload conditions based on one of a current level and a current change rate di/dt of a current through a load. A detection device uses an inductor to detect current change rate and a resistor to detect current level, and generates a first voltage...http://www.google.fr/patents/US7265959?utm_source=gb-gplus-shareBrevet US7265959 - Solid state switch with quasi-predictive short circuit protection and thermal protection
