Abstract: A system includes a first printed circuit board (PCB), a temperature sensor, a switching circuit provided on the first PCB, and a controller. The temperature sensor is configured to measure temperature of at least an area of the first PCB. The controller is configured to trigger the switching circuit to turn off power to the first PCB, based at least in part on the temperature sensor detecting a temperature above a temperature threshold. The system is able to disrupt power much faster than conventional methods of power protection which may have a blind spot to certain areas of the first PCB, since these methods rely on power disruption when a maximum power is sensed.
