摘要：
A method and a circuit for detecting an overheating of an electronic switch of power supply of a load by an A.C. voltage, in which a voltage representative of the temperature in the vicinity of the switch is compared with a threshold, the result of this comparison being sampled at frequency corresponding to an even multiple of the frequency of the A.C. power supply voltage, to provide a signal indicative of the fact that a temperature threshold has been exceeded.
