Abstract
An integrated circuit (IC) is provided. The IC includes a specific pin, a pull-down circuit and a voltage detector coupled to the specific pin, and a controller. The pull-down circuit includes a pull-down resistor corresponding to a driving voltage level, and is configured to selectively couple the pull-down resistor to the specific pin according to a control signal. The voltage detector is configured to detect the specific pin to obtain a detected voltage value. The controller is configured to determine whether the detected voltage value is the same as the driving voltage level, so as to provide the control signal. When the detected voltage value is greater or less than the driving voltage level, the controller is configured to provide the control signal to the pull-down circuit, so that the pull-down resistor is electrically separated from the specific pin.
