Abstract
A CPU power control circuit includes a temperature detection circuit, a power supply circuit and a discharge circuit. The power supply circuit is connected to the temperature detection circuit, a CPU and the discharge circuit. The discharge circuit is connected to the temperature detection circuit and the CPU. The temperature detection circuit is connected to the CPU for detecting the temperature of the CPU. When the temperature of the CPU exceeds a predetermined range, the temperature detection circuit outputs a high temperature signal. The power supply circuit receives the high temperature signal, and stops working. The discharge circuit receives the high temperature signal, and discharges the power supply circuit so as to stop supplying power to the CPU.
