Abstract
Anti-arcing circuits are described herein that are configured to prevent or substantially mitigate arcing when a power adapter is connected/disconnected from a client device. The anti-arcing circuit restricts power supplied when a connection of a connector of a power adapter to the adapter interface is not fully established. The anti-arcing circuit is further configured to detect when a connection is made and remove the restriction to supply power for operations of the client device. In one approach, the anti-arcing circuit includes two different paths and components associated with a detection mode and operational mode respectively. In the detection mode, power supply is suppressed and a current pulse may be sent to determine if a connection is established. If current is detected, a switch is made to operational mode and power for normal device operations is supplied.
