Abstract: Described herein are embodiments for dual-port communication and power delivery for one-wire applications. Embodiments of one-wire bridge devices are disclosed to provide a dual-port link for two one-wire masters to communicate with one another in a multi-voltage system while intermittently allowing charging voltage. The configuration may be used to set a bidirectional pass through mode that allows level shifted fast logic signals to pass through the two one-wire links. A timer may also be configurable to time-out the pass through mode from edge in-activity. Power may be derived for operation directly from one of the links, eliminating the need for an external power supply when local power is not available. When local power is available, the other one-wire link provides local access and the pass through mode. Such configurations make it easy for a two-contact solution to be both a communication channel and a power supply for battery charging.

Abstract: A sensor device may include an environmental sensor configured to sense an environmental parameter and generate a signal representative thereof, a single pair ethernet (SPE) interface configured to cooperate with an SPE link, and a controller provided in communication with the environmental sensor and the SPE interface. The controller may be configured to receive the signal representative of the sensed environmental parameter and to control the SPE interface to generate at least one ethernet frame including data indicative of the sensed environmental parameter for transmission over the SPE link. The controller may be further configured to automatically configure communication with a remote server over the SPE link via the SPE interface.
