Abstract
In described examples, an integrated circuit (IC) includes a first temperature sensor, a processor, a second temperature sensor, and a reset module. The first sensor senses a first body temperature of the IC. The processor asserts a thermal shutdown signal if the first body temperature exceeds a first threshold. In response to the thermal shutdown signal, the second sensor asserts a reset request signal and senses a second body temperature of the IC. If the second body temperature is less than a second threshold, the second sensor asserts a reset end signal. The reset module outputs a system reset signal to the first sensor and the processor if the reset request signal is asserted, and outputs a system recovery signal if the reset end signal is asserted. The first sensor and the processor deactivate if the system reset signal is asserted, and activate if the system recovery signal is asserted.
