Abstract
An exemplary reset circuit includes a first connection jack connected to a first power supply, a second connection jack connected to a second power supply, a reset IC, a voltage response module, and a control module. The voltage response module outputs a first response signal when the voltage provided by the second power supply is abnormal, and then the control module outputs a first voltage which is less than the voltage provided by the first power supply. The voltage response module outputs a second response signal when the voltage provided by the second power supply is normal, and then the control module outputs a second voltage which is equal to the voltage provided by the first power supply. When the voltage received by the reset IC is changed from the first voltage to the second voltage, the reset IC outputs a reset signal to reset the processing IC.
