Abstract: An integrated circuit (IC) includes input/output (I/O) ports, each operating using one of a pair of unequal power supplies during normal operation of the IC. A lower supply of the pair of unequal power supplies is required to be used as the power supply for the I/O port when a first input signal to the IC is received from an external source on a first I/O port of the I/O ports. The voltage range of the logic excursions of the first input signal is greater than the range from a magnitude of the lower supply to a constant reference potential. A regulation loop derives a derived lower supply having a magnitude equaling that of the lower supply from the higher supply of the pair of unequal power supplies, and applies the derived lower supply on a power supply node of the first I/O port.

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: High-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral operate such that high-speed components except for a host-side squelch detector are set or maintained in a deactivated state during an idle period of a micro frame. In an example, a start of a micro frame is detected on a data bus during a first time period. In a second time period after the first time period, the high-speed communication device determines whether at least one data packet is contained in the micro frame. When it is determined during the second time period that no data packet is contained in the micro frame, active components, except a squelch detector, are controlled to be inactive during a third time period after the second time period.
