Abstract: Disclosed are an electrostatic discharge circuit and a method for preventing malfunctions of an integrated circuit due to a reverse connection of a power source. The electrostatic discharge circuit includes at least one MOSFET for providing an electrostatic discharging current path, and a control circuit coupled to the at least one MOSFET. When an external power supply is reversely connected, the control circuit is configured to change a potential of a body of at least one MOSFET, such that the at least one MOSFET is turned off, thereby preventing the integrated circuit from malfunctioning caused by a current generated by the reverse connection of the external power source flowing through the at least one MOSFET.
