Abstract
A method and apparatus for protecting a circuit are provided. The method and apparatus may measure a physical quantity of a motor by an external physical stimulus, may calculate a counter electromotive voltage generated by the motor, based on the physical quantity, may compare the counter electromotive voltage to an output voltage, and may control a circuit connected to the motor to be open when the counter electromotive voltage is greater than the output voltage.
