An integrated circuit includes a rectifier circuit, at least one low power element, and a power protection element. The rectifier circuit includes two inputs to receive an input power supply and includes two outputs to provide a rectified power supply related to the input power supply. The low-power circuit element is coupled between the two outputs. The power protection element is coupled between the two output terminals. In a first mode of operation, the power protection element presents a high impedance to the two output terminals. In a second mode of operation, the power protection element has a first power protection characteristic. In a third mode of operation, the power protection element has a second power protection characteristic. The power protection element is adapted to shut down the low-power circuit element when in the third mode of operation.
