The invention provides a method used for thermal protection misreport prevention of an integrated circuit and a system thereof which are particularly suitable for wireless terminal equipment. The method includes the steps as follows: measuring the temperature of a protective point; comparing the measured temperature value with a thermal protection temperature threshold; and starting protective measures when the measured temperature value achieves and exceeds the thermal protection temperature threshold and lasts for more than preset time. In the invention, when timing is carried out on the temperature which is higher than the threshold by arranging a counting unit, the reliability of measuring results is ensured under the condition that temperature sensing units are higher than the threshold, so as to prevent thermal protection misreport caused by the reported temperature jumpiness of the temperature sensing units, particularly in a condition that the wireless transmission power is fluctuated greatly. By arranging more than two temperature sensing units, thermal protection misreport caused by invalidation of the temperature sensing units can be avoided, and the accuracy and the reliability of protection are improved.
