摘要： An integrated cable-termination circuit is presented that can be selectably automatically configured to terminate a signal cable in conformance with one of a plurality of electrical interface standards, including, for example, CCITT/EIA standards V.11/RS-422 and V.35. Selected termination configurations are maintained when input voltages exceed power supply voltages or when power to the circuit is removed. A plurality of cable-termination circuits are provided to form an integrated selectable cable terminator for selectably terminating multiple cables, each in conformance with one of a plurality of electrical interface standards.

摘要： A mixed-mode multi-protocol serial interface driver is presented. The driver operates in current-mode, voltage-mode, or both, and includes circuitry for conforming output signals to one of a plurality of selectable electrical interface standards, including, for example, CCITT/EIA standards V.35, V.11/RS-422, V.28/RS-232, and V.10/RS-423. A mode-select input signal selects a particular standard, and appropriate portions of the circuitry are enabled in response. Portions of the circuitry not enabled are placed in a high impedance state to prevent their interference with the enabled portions.

摘要： Circuits and methods for controlling load sharing by multiple power supplies are provided. In preferred embodiments, load share controllers utilize multiple voltage control loops to monitor the output voltages that are being provided by multiple power supplies connected to a load. These voltage control loops each generate a voltage control voltage that is proportional to the difference between the actual output voltage of the corresponding power supply and the desired output voltage. The voltage control loop with the highest voltage control voltage then controls a current control voltage generated in a current control loop for each power supply via a share bus. These current control loops then regulate the current provided by the corresponding power supplies so that those currents are all proportional to the voltage on the share bus. By monitoring the current control voltage in each current control loop, the voltage at the output of each power supply, and the direction of the current flowing between each power supply and the load, the circuits and methods of preferred embodiments of the invention can detect and account for out-of-regulation conditions, over voltage conditions, short circuit conditions, and hot-swapping conditions.
