Abstract

A device includes a relative temperature detector configured to determine a temperature difference between a device temperature sensed near a switch device and an ambient temperature sensed outside the switch device. The relative temperature detector is configured to generate a relative temperature output signal based on comparing the temperature difference to a relative temperature threshold. A power detector is configured to generate a power level signal based on comparing an indication of switch power of the switch device to a power threshold. The power level signal specifies whether the indication of switch power is above or below the power threshold. A thermal capacity control is configured to disable the switch device based on the power level signal specifying that the indication of switch power is above the power threshold and based on the relative temperature output signal indicating the temperature difference is above the relative temperature threshold.
