Abstract: An electrical circuit for driving a bus is described that includes at least one branch coupled to at least one signal line at a termination of the bus and a transmit data input configured to receive data that the electrical circuit drives across the bus. The electrical circuit also includes a current detection unit coupled to the at least one branch, which is configured to detect a current through the at least one branch. The electrical circuit also includes an over-current determination unit coupled to both the current detection unit and the transmit data input. The over-current determination unit is configured to determine an over-current condition at the at least one branch based on the current at the at least one branch and the data at the transmit data input.

Abstract: An electrical circuit for driving a bus is described that includes a plurality of branches coupled to at least one signal line at a termination of the bus and a transmit data input configured to receive data that the electrical circuit drives across the bus. The electrical circuit also includes an over-current validation unit coupled to the transmit data input which is configured to validate an over-current condition detected at a first branch of the plurality of branches based at least in part on the data at the transmit data input. The electrical circuit also includes a branch control unit coupled to the over-current validation unit which is configured to disable at least one of the plurality of branches in response to a validated over-current condition at the first branch.
