Abstract
Technologies are described herein for a two-wire power delivery system that may be employed by a mobile device with a reversable cable. The described techniques allow for the two-wire power cable to be inserted in any orientation into the mobile device, without requiring a special keying or registration element, and without requiring any additional pins or wires. The mobile device includes a passive protection circuit that assists the two-wire power cable system in detecting the correct orientation for power delivery.
