Abstract

An over-temperature protection circuit applied in a motherboard platform includes a first processor, a second processor, and a peripheral circuit. The first processor includes first temperature detection unit, the second processor includes second temperature detection unit. The over-temperature protection circuit includes third temperature detection unit and digital processing unit. The first processor can determine that the motherboard platform is in an over-temperature state through the first temperature detection unit, the second processor can determine that the motherboard platform is in the over-temperature state through the second temperature detection unit, and the digital processing unit can determine that the motherboard platform is in the over-temperature state through the third temperature detection unit. When an over-temperature state is determined by any such means, the first processor controls the motherboard platform to enter a sleep mode.
