Abstract: An integrated circuit includes an overvoltage protection circuit. The overvoltage protection circuit detects overvoltage events at a pad of the integrated circuit. The overvoltage protection circuit generates a max voltage signal that is the greater of the voltage at the pad and a supply voltage of the integrated circuit. The overvoltage protection circuit disables a PMOS transistor coupled to the pad by supplying the max voltage signal to the gate of the PMOS transistor when an overvoltage event is present at the pad.
