Abstract
A power switch includes a first transistor and a second transistor, coupled in series between a first power supply voltage and a pad. The power switch also includes an analog multiplexer (MUX). The MUX is configured to provide a pad voltage to a control electrode of the first transistor when an overvoltage (OV) condition is detected on the pad, a second power supply voltage to the control electrode of the first transistor when an undervoltage (UV) condition is detected on the pad, and a reference voltage to the control electrode of the first transistor when neither the UV condition nor the OV condition is detected on the pad. The first power supply voltage is greater than the second power supply voltage, and the reference voltage is a fraction of the first power supply voltage.
