Abstract: A protection circuit includes a coding chip, a digital-to-analog converter (DAC), and a control circuit. The coding chip receives parallel voltage identification definition (PVID) signals or serial voltage identification definition (SVID) signals from a central processing unit (CPU), and converts the PVID signals or the SVID signals to voltage identification definition (VID) signals. The DAC receives the VID signals from the coding chip, and converts the VID signals to an analog voltage. The control circuit receives the analog voltage from the DAC and a voltage received by the CPU, and compares the analog voltage from the DAC with the voltage received by the CPU. When the voltage received by the CPU is greater than the analog voltage from the DAC, the control circuit disconnects the CPU from a first power supply.

Abstract: A fan circuit controls a speed of a fan. A control chip outputs a pulse width modulation (PWM) signal that changes with the temperature of an electronic device that the fan is mounted in. An input circuit converts the PWM signal into a continual voltage signal. An amplifier circuit amplifies the voltage signal and outputs a control signal. When the control signal is less than a threshold voltage, the control circuit is turned on and the fan receives current which is less than preset current. When the control signal is greater than the threshold voltage, the control circuit is turned off and the fan receives current which is greater than the preset current.
