Abstract
Methods and systems are disclosed for protecting a host device from one or more power surges transmitted from a sink device. When a sink device is detected as being connected to the host device, a limited level of power is provided to the sink device over a power transmission line and the sink device is authenticated. A normal level of power is provided to the sink device only if the authentication is successful, otherwise a reduced level of power is provided.
