In this example a power FET driving a brushless DC motor cannot operate above 125 °C, and it is known that there is a potential issue with the FET if the temperature rises faster than 20 °C/s. This rapid change in temperature will lead to a runaway thermal condition unless the current is reduced.
The accuracy of the temperature sensor should remain within 1 °C throughout its temperature range. And the temperature sensor has a conversion period error of 15 %. A timing error of 15 % would indicate that for a given conversion period setting, the conversion period can be ±15 % of the setting.
