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.
