System and method for dual-port communication and power delivery

A method for bridging single wire communications, comprising:

• coupling a first interface of a dual-port circuit to a first circuit via a first single wire link;
• coupling a second interface of the dual-port circuit to a second circuit via a second single wire link;
• coordinating operation of the first single wire link and the second single wire link by enabling one of the first single wire link and the second single wire link for single wire data communication at a given time, a buffer is in communication with the first and second single wire links and is configured to transfer data during single wire data communication;
• and upon activation, establishing a bidirectional level translation between the first single wire link and the second single wire link in a pass through mode;
• wherein in response to a voltage on the first single wire link being higher than a predetermined threshold voltage, enabling charging activity using the voltage on the first single wire link, the predetermined threshold voltage is higher than an operation voltage on the first single wire link for data communication.
