Abstract
Embodiments herein relate to controlling a connection to an interface. In an embodiment, a protection circuit is to detect a voltage at an input rail of a regulator, where the regulator is to provide power to a peripheral device via an interface. Next, the protection circuit is to compare the detected voltage to a reference voltage. Then, the protection circuit is to generate a detection signal based on the comparison. Lastly, the protection circuit is to disable a connection between the regulator and the interface based on the detection signal.
