摘要： A protection circuit for a parallel power system having at least two parallel coupled voltage regulators is disclosed. The protection circuit includes at least two isolation control circuits, each control circuit being coupled to a respective voltage regulator. Each isolation control circuit includes a current sense circuit for sensing current polarity at an output of the respective voltage regulator, and a controller for automatically isolating the respective voltage regulator when an over-voltage condition exists at an output of the parallel power system and a positive current polarity is sensed at the output of the respective voltage regulator. The at least two isolation control circuits isolate only a voltage regulator having positive current outflow during the over-voltage condition. In one embodiment, each isolation control circuit further includes an over-voltage detection circuit for detecting when the over-voltage condition exists at the output of the parallel power system.

摘要： In a bi-directional, self-synchronous bus for communication between semiconductor devices, a logic delay is provided as a flag to a state machine control for indicating that the bus is making a transition from a low to a high state. The logic delay causes the bus to adaptively idle until the bus settles, making it amenable for a wide variety of bus sizes and topologies. In this way, oscillation of the bus is avoided without slowing the speed of the state machine clock.

摘要： One or more multiport systems are used to facilitate servicing of asynchronous communications events. A multiport system, such as an open collector multiport system, receives from one of a plurality of source components an asynchronous communications event directed to a target component coupled to the plurality of source components. The multiport system is controlled to provide, at any given time, a communications path between a plurality of ports of the multiport system to service the asynchronous communications event. One or more multiport systems are used to forward the event from the source to the target.

摘要： An arbitration mechanism is provided for arbitrating between redundant controllers having outputs electrically connected together and provided as input to at least one device under control. The arbitration mechanism includes logic for automatically determining which controller of the redundant controllers is active controller, and a hardware output interlock for the redundant controllers to ensure that output controlled by only the active controller is enabled as input to the at least one device. The arbitration mechanism also includes logic for monitoring the active controller for failure, and upon detection of failure, for automatically switching active control to another controller of the redundant controllers transparent to the at least one device.

摘要： A method for data access via an inter-integrated circuit (I2C) protocol. The method includes receiving an I2C read command at an I2C slave device, where the I2C read command is from an I2C master device. The method also includes reading stored data from a storage device in response to receiving an I2C read command. The stored data is at a first location in the storage device corresponding to a value in a register array pointer in the I2C slave device. The stored data is transmitted to the I2C master device in response to the reading. The method also includes receiving an I2C write command at the I2C slave device, where the I2C write command is from the I2C master device and the write command includes master data and a slave device register address. The master data is written to the storage device in response to receiving the I2C write command, with the master data being written at a second location in the storage device corresponding to the slave device register address.

A second isolation device in also included in the bidirectional link and connected to the second bus for transmitting signals over the bidirectional link from the slave device referenced at the second voltage to the master device referenced at the first voltage.
